Q: How does laser therapy work?
A: The actual mechanism by which Low Level Laser Therapy (LLLT) stimulates hair growth (i.e., increases the anagen phase of the hair cycle) is unknown, but possible mechanisms include the following: stimulation of growth factors, dilation of follicle blood vessels, or increasing the production of ATP (molecular energy).
Q: Hi Dr. Bernstein, I am a 30 year old man with a balding crown. I’m 99.9% sure its male pattern baldness (I’m currently on Propecia and Rogaine). I recently read about how people going bald are getting tested for LPP (lichen planopilaris). Do you perform this test?
A: Lichen Planopilaris (believed to be a type of autoimmune disease) occurs more frequently in women than in men and more commonly in African-Americans than in Caucasians. The variation that could be confused with androgenic alopecia in men is central centrifugal cicatricial alopecia (or CCCA). While definitive testing would involve a scalp biopsy, this is rarely necessary as the doctor can easily tell by just examining you with the naked eye using magnification (densitometry).
Q: How common is hair loss in adult men and women?
A: The incidence of androgenetic alopecia (common baldness) is quite high for both men and women. By age 50, 50% of men and 30% of women are affected. By age 70, that increases to 80% of men and 60% of women. Fortunately, in spite of significant thinning, women often preserve their hairline and have a diffuse pattern, so there hair loss can be camouflaged for many years.
Q: What is Lichen planopilaris?
A: Lichen planopilaris (LPP) is a distinct variant of cicatricial (scarring) alopecia, a group of uncommon disorders which destroy the hair follicles and replace them with scar tissue. LPP is considered to have an autoimmune cause. In this condition, the body’s immune system attacks the hair follicles causing scarring and permanent hair loss. Clinically, LPP is characterized by the increased spacing of full thickness terminal hairs (due to follicular destruction) with associated redness around the follicles, scaling and areas of scarred scalp.

The terms DPA and DUPA were first described by O’tar Norwood in his seminal 1975 publication: Male Pattern Baldness: Classification and Incidence.
Q: What is Saw Palmetto? — R.P., White Plains, NY
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 have been on finasteride for about 7 months. After my latest haircut I can see that my scalp is shiny. I read that is from sebum buildup and it can cause a layer that clogs the growth of hair. I was wondering if this is true and, if so, how can it be treated? — T.C., Philadelphia, PA
A: It is not true. Hair loss is caused by the miniaturizing effects of DHT on the hair follicle, not by blocked pores.
Q: What happens to hair diameter when you age?
A: From infancy to puberty, hair gets progressively thicker. From adulthood to old age the hair becomes thinner again and this is exacerbated by the effects of DTH in susceptible persons. The later process is called androgenetic alopecia (common baldness) and is characterized by miniaturization – the progressive decrease in hair diameter and lengths as a result of DHT.
However, even without the effects of DHT, hair gradually thins over time in many people.
Q: It seems like my hair is thicker in the summer. Can this be true?
A: Hair will increase in diameter when there is more humidity, as it absorbs moisture, and will actually be thicker in the more humid summer environment.
Q: What color hair is the thickest? I thought it was brown, followed by red then blonde? But I am also reading that red is the thickest but redheads have the fewest hairs.
A: In very general terms, the darker the hair, the thicker it is and the lower the density (hairs per area). For example, Asians have the darkest hair, the highest hair diameter and the lowest density. Scandinavian blonds have very high hair density and the fine (diameter) hair. But there are many exceptions, African Americans have black hair, but it is usually very fine and of low density. I have seen red heads in all categories.
Q: I am a 47 year old woman with thinning on the top of my scalp for three years. I think I want to go for a comprehensive evaluation for hair loss and know that the doctor may want to take blood tests to help find out the cause of my hair loss. I am […]
Q: Why do some people have a full head of hair into their seventies or eighties and others start to go bald in their late teens or early twenties? A: The difference is genetic with the inheritance coming from either side of the family. Although a person will have the genes his/her whole life, a […]
Q: I have a quite a bit of hair on my chest, back and legs. Is that an indicator of future baldness? A: Although bald people joke around that they wish the hair on their body (and ears) was on their head, body hair is not an early sign of baldness.
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 […]

Our consults are […]
Q: Why is the consult fee more for diffuse thinning than for a regular visit? A: Diffuse hair loss, more common in women, can be the result of a number of underlying medical conditions and therefore it usually requires an extended medical evaluation. If you are a male or female with obvious diffuse thinning from […]
Q: Do you use computer type imaging to create the best way to insure you (or any hair transplant surgeon) have the same goal or target “picture” of the particular patient’s restoration as that particular patient has as his “picture?” A: I prefer not to do imaging since it tends to oversell the hair restoration […]
Q: Can stress produce diffuse unpatterned hair loss (DUPA), or was it bound to happen anyway? A: Both DPA (diffuse patterned hair loss) and DUPA (diffuse unpatterned hair loss) are genetic conditions, unrelated to stress and would have happened anyway. These types of hair loss are characterized by a high percentage of mininiaturized hair in […]
Q: I’ve been dealing with daily mental stress for the past few months. I’ve notice that during that time, I’ve experience a lot of frontal hair loss and thinning.

Q: Dr. Bernstein, why have you not had a hair transplant? I’m sure this question gets asked a lot. Thanks. A: Yes, all the time. My donor area is very thin (so I am not a good candidate) and I have gotten used to being bald. It has been years.
Q: I have read that in the evaluation of a patient for hair restoration surgery some doctors use a densitometer to measure miniaturization – the decrease in size of hair diameters. I read that miniaturization is a sign of genetic hair loss, but when there is miniaturization of greater than 20% in the donor area, […]
Q: Dr. Bernstein, I saw you on TV where you explained why you haven’t had a hair transplant. If you had better donor hair and you could do the surgery on yourself, then would you consider having a hair transplant? A: Yes.
Q: Will cutting my hair short – skin level – adversely affect it? A: Hair shafts are not alive (only the follicle is) so cutting the hair will not affect its growth.
Q: I seem to be thinning, but I never shed hair as such in the shower. I cannot see my hair falling out. Can it be androgenetic hair loss? A: In androgenetic hair loss one rarely sees hair falling out in mass, but rather the thinning is due to the hair decreasing in diameter and […]
Q: If I’m 20 years old and haven’t lost any hair yet, should I start using a laser comb now? A: One should not treat hair loss until it actually occurs. That said, once there is clear evidence that if a person is thinning, non-surgical treatments are best started early to prevent further hair loss. […]

Q: I was told that if men have a lot of testosterone that that’s when they lose hair. Is this true? 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 […]
Q: Dr. Bernstein, I was reading about a densitometer on your website. What is it and what is it actually used for?

Q: What are “Senior Medical Consultants”? A: These are non-medical personnel who wear white coats to give the impression that they have formal medical training. They are actually salespersons and they should immediately identify themselves as such. Although non-medical personnel can help to answer general questions, they should not be examining you and making specific […]
Q: Can a hair transplant into bald areas caused by alopecia areata ever be successful? A: Alopecia areata is an autoimmune disease in which the body attacks its own hair follicles.
