Q: I had a good friend get a transplant at your practice and it seems that your practice is the industry leader in hair transplantation. I may one day be looking for one. That being said, my friend said I shouldn’t trust anyone else. I wanted to know if you may be able to tell me what tests/specific labs you have your patients do prior to starting Propecia. I am having my doctor put me on it but he does not recommend any labs but I don’t trust this. So I’m not looking for medical advice, just what your practice may advise a patient to get (in terms of labs/blood tests) prior to starting Propecia. I’m really hoping you can help as I have already contacted a number of other sources and can’t seem to get an answer. — M.B. ~ Upper East Side, N.Y.
A: Blood tests are not required before starting finasteride and we do not routinely perform them. If a patient requests test then Total and Free Testosterone, DHT, and Prolactin are reasonable to obtain, but there is no consensus on what the appropriate tests might be. If a patient requests tests because he has symptoms (i.e. such as lack of energy associated with low T), he should see his internist, urologist, or GP. That said, patients 50 and over (40 and over in patients with a high risk of developing prostate cancer) should have a PSA before starting finasteride.
A study published in the British Journal of Dermatology suggests that subcutaneous placement of testosterone pellets may boost hair regrowth in some women. ((Glaser RL, Dimitrakakis C, Messenger AG. Improvement in scalp hair growth in androgen-deficient women treated with testosterone: a questionnaire study. Br J Dermatol. 2012 Feb;166(2):274-8.))
This retrospective analysis examined patients who had androgen deficiency. Of the 285 patients studied, 76 had some degree of hair loss prior to beginning treatment. At one year on testosterone replacement 63% reported an increase in hair regrowth on the scalp.
Traditionally, elevated levels of androgens, such as testosterone, are felt to be the primary cause for common hair loss in both men and women. This is due to the seemingly adverse effect of androgens on hair follicles. This has held true for most men with patterned hair loss in whom DHT-blockers, such as Propecia (finasteride) and Avodart (dutasteride), have proven to be a potent remedy.
Given this, it was surprising that none of the 285 women in the study who had been treated with testosterone reported any hair loss after one year. In fact, of the 76 women who initially reported hair loss before the study, 63% reported positive hair regrowth at one year.
The researchers noted that patients with a “significantly higher body mass index (BMI)” were in the subset of those who did not regrow any hair. This suggests that a higher dose might be needed in some patients. ((Kapp N1, Abitbol JL2, Mathé H2, Scherrer B2, Guillard H2, Gainer E2, Ulmann A2. Effect of body weight and BMI on the efficacy of levonorgestrel emergency contraception. Contraceotion. 2015 Feb;91(2):97-104. doi: 10.1016/j.contraception.2014.11.001. Epub 2014 Nov 8.)), ((Lopez LM, Grimes DA, Chen M, Otterness C, Westhoff C, Edelman A, Helmerhorst FM. Hormonal contraceptives for contraception in overweight or obese women. Cochrane Database of Systematic Reviews 2013, Issue 4. Art. No.: CD008452. DOI: 10.1002/14651858.CD008452.pub3)), ((Glasier A, Cameron ST, Blithe D, Scherrer B, Mathe H, Levy D, Gainer E, Ulmann A. Can we identify women at risk of pregnancy despite using emergency contraception? Data from randomized trials of ulipristal acetate and levonorgestrel. Contraception. 2011 Oct;84(4):363-7. doi: 10.1016/j.contraception.2011.02.009. Epub 2011 Apr 2.))
Summary
By correlating higher levels of testosterone with more hair growth and/or retention in women, the study bolsters the idea that hair loss in men and women is caused by different mechanisms. Though not conclusive, the study opens the idea that testosterone implantation can effectively treat hair loss in women.
Q: Does finasteride need to be taken every day? — M.B., Atlanta, GA
A:Finasteride (Propecia) is a competitive inhibitor of Type II, 5 alpha-reductase (5AR is the enzyme that converts Testosterone to DHT which then causes hair to miniaturize and eventually be lost). Finasteride is 100x times more selective in inhibiting the Type II enzyme (present in hair follicles) than the Type I enzyme (present in other body tissues). The turnover (T1/2) of the finasteride/5AR Type II complex is 30 days and the finasteride/5AR Type I complex is 15 days. This explains why finasteride does not need to be taken every day and why, after stopping finasteride, the effects may take a month or longer to begin to disappear.
Q: The last few months my friend and I experimented with andro gel thinking it would make our T levels go up and make our work outs better. We got the andro gel online with no prescription (which I know is really stupid on our behalf). The past couple of months I have been experienced a lot of acne and hair loss. I went to the doctor and confessed and said what I did, and he was very disappointed and lectured me on how dangerous it was and stupid on my behalf – which I totally agree. He told me the rise in testosterone from andro gel contributed to the acceleration of hair thinning and acne. I had mild hair loss prior but the andro gel seem to have accelerated it. The doctor put me on Propecia and gave me some acne cream for the acne. He said the Propecia will undo some of the damage it did for the hair. In your experience, can Propecia reverse some of the damage? I am 28 years old.
A: Your doctor is giving you the right course of action. Testosterone supplements can accelerate hair loss, particularly in those with underlying genetic hair loss. Finasteride 1mg (Propecia) should help you to grow your hair back. You may also want to consider using minoxidil (Rogaine) in addition.
A study of Australian men between the ages of 40 and 69 suggests that men who were mostly bald by the age of 40 were more likely to develop prostate cancer in their 50s or 60s. The Melbourne Collaborative Cohort study of about 10,000 men showed that men who have high levels of testosterone may be more vulnerable to cancerous prostate tumors.
The team of scientists that conducted the long-term study, which was published in the journal Cancer Epidemiology, Biomarkers and Prevention, reported that both baldness and prostate cancer are age-related and androgen dependent conditions, so these findings are not surprising. The statement said, “We found that baldness at the age of 40 might be a marker of increased risk of prostate cancer.”
A:Saw Palmetto is a dwarf palm plant native to North America. The active ingredients can be found in the plant’s brown-black berries. It is proposed that it blocks the enzyme 5-alpha-reductase that converts testosterone to dihydrotestosterone (DHT). There is little scientific evidence that Saw Palmetto is actually effective for hair loss.

Q: I’m concerned that finasteride might result in unwanted body hair on the arms, back, etc. Is there any truth to this? My thinking is that since finasteride blocks the enzyme 5 alpha-reductase which converts testosterone to its more active form, DHT (dihydrotestosterone), is it possible that it might actually have some effectiveness in ameliorating unwanted hair? — P.P., Stamford, CT
A: Yes, finasteride does have some ability to decrease body hair, since growth of body hair is stimulated by DHT. However, the effects of finasteride are mild and not observed by everyone, so if you have unwanted body hair you will probably need some other means to remove it such as waxing, laser hair removal or electrolysis. The important thing is that finasteride doesn’t increase body hair.
Q: Hi! I wanted to ask if after hair restoration surgery the transplanted hair will eventually fall out? Because the surgery is to restore hair mainly for people with genetic hair loss which results from DHT, won’t the DHT make the new follicles implanted fall out as well? — B.C., Stamford, C.T.
A: Hair loss is due to the action of DHT (a byproduct of testosterone) on hair follicles that cause them to shrink and eventually disappear (the process is called miniaturization). The follicles on the back and sides of the scalp are not sensitive to DHT and therefore don’t bald (miniaturize).
When you transplant hair from the back and sides to the bald area on the front or top of the scalp the hair follicles maintain their original characteristics (their resistance to DHT) and therefore they will continue to grow.
Q: My son, 25 years old, is seeing hair loss around the hairline. According to your website, he is probably a stage II. He may have a little hair loss at the vertex; right now it is hard to tell. He is very muscular and loves weight lifting, but no drug enhancement. Is there a relationship between weight lifting and hair loss, since I have read that weight lifting increases testosterone levels? — G.S., Pleasantville, NY
A: Yes, weight lifting does increase testosterone, which in turn increases DHT. This can accelerate hair loss, although the effect is generally very slight.
Rather than modify his exercise program, your son may want to consider taking finasteride (Propecia). This requires a doctor’s prescription.
Q: I am a 21 yrs old male having serious hair loss over the last few years. I also have very little facial hair. Since Propecia is a DHT blocker can it inhibit beard growth? — E.M., Astoria, N.Y.
A: As you suggest, it would be reasonable to assume that since DHT stimulates beard growth, blocking DHT (with finasteride) would tend to inhibit its growth. In practice, this does not seem to be the case, i.e. we don’t find that Propecia has any effect on facial hair. The reason is not clear.
It is interesting to note that testosterone stimulates growth of axillary and pubic hair, but not scalp hair. Scalp hair growth is not androgen dependent, only scalp hair loss is.
DHT stimulates terminal hair growth of the beard, trunk and limbs, external ears and nostrils. Of course, it also is responsible for the bitemporal reshaping of hairline as one passes into adulthood and causes male patterned baldness (androgenetic alopecia).
Q: I’m 52 years old and have been taking Propecia (finasteride) for two years. It seems to maintain the status quo with no apparent regrowth. I am considering adding a dose of Avodart (dutasteride) once a week in conjunction with the daily Propecia. My question is twofold: (1) Since dutasteride blocks production of both enzymes (type I and II) that produce DHT from testosterone, is it redundant to take the finasteride that only blocks the type I enzyme? — Y.B., Orlando, Florida
A: It is redundant to take both.
However, you may not be taking the optimal dose of dutasteride which seems to be at least 0.5mg a day for hair loss.
Q: Some non-steroid athletic nutritional supplements claim to increase testosterone. Assuming they worked, would increasing testosterone increase DHT and hair loss?
A: Yes, if they were effective in increasing testosterone then they may accelerate hair loss.
Q: My friend is taking Avodart, he bought it over the internet. Is it safe to take? — T.G., Denver, Colorado
A:Avodart (dutasteride 0.5mg) was approved by the FDA for the treatment of prostate enlargement in men in 2002. Avodart has not been approved for the treatment of androgenetic hair loss, although physicians can use an approved medication in ways other than for which it was specifically approved. That said, the use of dutasteride certainly requires a doctor’s supervision.
Like finasteride (the active ingredient in Proscar and Propecia), dutasteride blocks the enzyme 5-alpha reductase that converts testosterone to DHT (DHT is a key hormone that causes hair loss). However, unlike finasteride, which only inhibits the Type I form of the enzyme, dutasteride inhibits both the Type I and Type II forms. This combined effect lowers circulating DHT more with dutasteride than with finasteride, but also increases the incidence of its side effects.
The Type II form of the enzyme (blocked by finasteride) is found predominantly in the hair follicle. The Type I form of the enzyme has been found in the scalp and sebaceous glands, and many other parts of the body, but its exact role in hair growth has not been determined. It is felt that dutasteride’s ability to dramatically lower serum levels of DHT is what makes it a more potent medication in hair loss.
When considering the safety of dutasteride, one should consider the following:
It acts on other parts of the body besides the hair follicle.
Unlike finasteride, where families that had a deficiency of the Type II 5-alpha reductase enzyme were followed for years without any adverse effects, there is no natural biologic model to show the safety of dutasteride.
Dutasteride has been approved for prostate enlargement in an older male population. It is not approved for hair loss and, in fact, the clinical trials for hair loss were discontinued, so there is no safety data for its use in younger patients. There is a greater incidence of sexual side effects with dutasteride compared to finasteride.
The 1/2 life of dutasteride is 5 weeks compared to 6-8 hours for finasteride. Serum concentrations of dutasteride are detectable up to 4-6 months after discontinuation of treatment.
Q: I was told that if men have a lot of testosterone that that’s when they lose hair. Is this true? — Y.B., Lake Forest, Illinois
A: Although androgenetic hair loss is dependent upon normal levels of testosterone, it is not due to increased testosterone. It is caused by a sensitivity of the follicles to normal levels of testosterone.
So someone that is bald doesn’t have extra levels of male hormones and is not necessarily over-sexed.
Q: Dr. Bernstein, a lot of older women are taking testosterone to restore libido, but are they going to experience hair loss as a consequence?
A: They can. In women there is a delicate balance between the androgens, i.e. testosterone and estrogens. Estrogen is protective to some degree against hair loss in women, which is why most women don’t experience such severe hair loss as do men.
When a woman takes testosterone supplements it upsets that balance and can cause hair loss. However, hair loss in post-menopausal women is usually due to age related changes. Typically, the hair decreases in size in a genetically determined progression that seems not to be directly related to changes in the levels of hormones.

Q Do Rogaine and Propecia work synergistically? — N.W., Chappaqua, N.Y.
A: They are synergistic, since the mechanisms of action are different.
Rogaine directly stimulates hair growth, while Propecia is permissive for hair growth by blocking DHT, the byproduct of testosterone that causes hair to miniaturize and eventually disappear.
The important thing to remember, however, is that for most people, Propecia is far more effective.
Q: I know that I am going to be bald because my father is bald and I am losing my hair just like him. What actually causes this kind of hair loss? — J.P., Paradise Valley, Arizona
A: Although there are many different causes, the overwhelming number of people that have hair loss have what is referred to as “patterned hair loss” or “androgenetic alopecia.”
In men, it is due to a hormone called DHT, which is a by-product of testosterone produced by the action of the enzyme 5-alpha reductase. This enzyme is inhibited by the hair loss medication Propecia. See the causes of hair loss in men page on the Bernstein Medical – Center for Hair Restoration website for more information.
In women, the mechanism is a little bit more complex as another enzyme, aromatase, is involved in the metabolic pathway. See the causes of hair loss in women page on the Bernstein Medical – Center for Hair Restoration website for more information.
We know that the inheritance comes from both the mother’s and father’s side, although the actual genes causing hair loss in men and women have not yet been identified. Statistically, the inheritance from the maternal side appears to be a bit stronger, but the reason for this is unknown.
Q: Why does a hair transplant work? – L.L., Salem, Massachusetts
A:Hair transplantation works because hair taken from the permanent zone in the back and sides of the scalp maintains its original characteristics when transplanted to a new place in the balding area in the top of the head. This property of hair is called “donor dominance” and is the reason why hair transplants are possible.
The hair follicles in areas that go bald are genetically susceptible to DHT, a breakdown product of testosterone. In response to DHT, these hair follicles miniaturize (decrease in size) until they eventually disappear. When follicles from the permanent zone, that are resistant to the effects of DHT, are moved to a balding area, they maintain this property and continue to grow.
Dr. Bernstein was interviewed by New York Newsday in their article, “It’s a Hairy Decision Picking a Treatment for Baldness.” The complete article is below:
HEALTH MATTERS COLUMN
Even IF they don’t talk much about it, just about all the guys he knows are taking medication for their thinning hair, said Steve, a retail manager in his early 30s from Suffolk County, NY. He would be too, but he had side effects right away. He’s had consultations for hair transplants, but that won’t work either because of the pattern of his balding.
So he’s using a protein product that makes his hair look fuller, changed his diet to include leafy green vegetables, gone to two psychics for help. And, he said, he’s biding his time, waiting for new hair restoration medications or for hair cloning to hit the marketplace.
“In the ’90s, everything’s about looks,” said Steve, who asked that his last name be kept confidential. “No one wants to give up their youth.” All the effort to find a hair restoration solution is worth it, he said, “because losing my hair bothers me a lot.”
Sure, hair loss isn’t crippling or life-threatening. But to hear people’s tales, it’s traumatic, depressing and embarrassing.
Yet, you’re more likely to get a snicker than a hug for your pains, said Spencer Kobren, 34, a Manhattan consumer activist and author of “The Bald Truth,” (Pocket Books, 1998, $6.99.) There may be few open arms to comfort you, he said, but there are plenty of extended hands to take your trust and your money.
Kobren should know. He has spent several years testing out hair loss products and talking to the experts about his own hair loss, which began at 22. Now he serves as a sounding board and clearinghouse for the good news and the bad about hair loss and its treatments on a syndicated radio show, aired locally on WEVD /1050 AM on Sunday nights.
“You feel like you’re losing a part of yourself. You see your appearance deteriorate, often rapidly and drastically,” he said. You become vulnerable to promises and pitches, but don’t be swayed by them, said Kobren, who now has a full head of hair. Instead, do a lot of research. The wrong hair restoration products or treatments may not only fail to grow hair, they can make matters a lot worse. For example, he said he gets thousands of letters and e-mails about botched hair transplants that leave men scarred, poorer and balder.
According to Kobren, about $7 billion is spent by consumers annually on finding solutions to hair loss. There are about 50 million men who are balding, with at least 20 percent starting in their 20s. Most have male-pattern baldness, genetically linked and triggered by the action of a hormone called dihydrotestosterone (DHT).
Hair loss is not just a guy thing, though. Plenty of women — about 20 million — have varying degrees of it too. Hair loss is finally getting recognition as a women’s health problem, said Maggie Greenwood- Robinson, whose book, “Hair Savers for Women” (Three Rivers), is due next spring. Kobren’s “The Truth About Women’s Hair Loss,” (Contemporary) will be out in January. “There are more options than ever before for women with hair loss,” said Greenwood-Robinson, and they shouldn’t give up.
But they do have to be cautious. The diagnosis and treatment for men and women is very different, said Dr. Robert M. Bernstein, assistant professor of dermatology at Columbia College of Physicians arid Surgeons and medical director of the New Hair Institute in Manhattan and Fort Lee, N.J.
“Women usually have a diffuse type of hair loss with thinning all over,” he said, “while men generally lose hair on the front and top and keep a permanent zone on the back and sides.” Female baldness can also be due to DHT, but many women lose hair because of anemia, gynecological issues, thyroid disorders or stress, among other reasons. You don’t want to waste your efforts on hair restoration products when what you need is more iron or different birth control pills. “A medical evaluation is extremely important to rule out underlying medical conditions,” said Bernstein.
The treatment of hair loss is an increasingly complicated decision for both men arid women, but at least there is more information than ever to help you ask the right questions. Web sites include www. thebaldtruth.org and www.regrowth.com. Bernstein’s practice has a Web site at www. newhair.com and a detailed book called “The Patient’s Guide to Hair Restoration.”
Your hair restoration options include:
Medication: Finasteride (brand name Propecia), taken orally by prescription. Available for under two years, Propecia is for men only and causes side effects in about 2 percent of them. It has been shown to stop hair loss in about 87 percent of users and new growth in about half. It’s not for women, because it can cause birth defects if a woman is pregnant, and if she’s past child-bearing age, it doesn’t seem to work.
Minoxidil: (brand name Rogaine), used topically. It can be used by both men and women and appears to slow down the rate of hair loss, but not to prevent balding in the long haul. Any effect from either of these hair restoration medications stops when you no longer use them.
Hair transplant surgery: for men and women. Bernstein has pioneered a state-of-the-art technique called follicular unit transplantation, a precise method using hair-follicle groupings that result in a more natural growth of hair and doesn’t leave scars.
Removing grafts of skin from your head and placing them in balding spots is clearly an art as well as a science. Besides being a good candidate for surgical hair restoration, you need to find a dermatologist with a lot of experience performing hair transplant surgery. Expect to ask many questions, learn the risks, see pictures of other patients and meet them in person.
CBS News has enlisted the help of Dr. Bernstein in dispelling a series of myths which circulate in the general public about the causes and treatments of hair loss. The feature is titled, Hey, Baldy: 10 Things You Need to Know about Hair Loss.
