Dr. Eric S. Schweiger, associate at Bernstein Medical – Center for Hair Restoration and board-certified dermatologist, is quoted in a few recent articles on the effects of chemotherapy on hair, genetic testing for hair loss, and caring for a bald or balding scalp. The articles were published in Energy Times and HairLoss.com. View the full post to read what Dr. Schweiger has to say on these topics.

Q: I am currently taking Avodart and have done so for around 8 months. Last night I had a significant loss of hair after taking a shower, nothing like I have ever seen before and found it very distressing. Can you tell me if this is hair loss or could it be something known as shedding and could you please tell me what is the difference between hair loss and hair shedding?

A: Hair loss is a very general term that can refer loss of hair for any reason. Genetic hair loss is caused by the effects of DHT on hair follicles that result in miniaturization -– i.e. a slowly progressive change in hair diameter that starts with visible thinning and that may gradually end in complete baldness. Hair shedding is more sudden where hair falls out due to a rapid shift of hair from its growth phase into the resting phase. The medical term for this is telogen effluvium. This process is usually reversible when the offending problem is stopped. It can be due to stress, medication, or other issues. You should see a dermatologist to figure out which process is going on. Dutasteride can cause some shedding when it first starts to work, but it would be unusual to do this after being on treatment for eight months.

Q: I am a 34 year old male and my dermatologist prescribed Propecia for me today. Most of my hair loss is at the hairline, but there is some loss on top as well. It’s not bad, I just want to stay ahead of it. If I get a transplant I want to get it at your clinic, but I will give the Propecia a try first. I am going to be overseas for a couple of months starting this Sunday and I was wondering about the necessity or desirability of having someone measure my hair density prior to starting the Propecia. Would you advise waiting to start the Propecia until I come back in two months and having my density examined at your clinic?

A: I would start Propecia as soon as possible. What is important for a hair transplant is the density in the donor area and this is not affected by Propecia (or minoxidil). Your donor density can be measured anytime at an evaluation prior to surgery. If you want to wait to see the effects of Propecia prior to the hair transplant, you really should wait a year; since growth, if any, can take this long. If you just want to have Propecia on board for the hair restoration procedure, or to make sure you don’t have side effects, then generally a month will do. If you would like to do a photo consult through our website to get some preliminary information about how many grafts you might need, you can do that at your leisure, but start Propecia now since the longer you wait the less effective it will be at regrowing hair.

Q: I have done a lot of research over the past year including seeing a dermatologist and receiving consultation from a surgeon. Both recommended Propecia and Rogaine. My confidence in their advice was lost when I researched each of these products and found that they do not improve receding hairlines, only lost hair in the crown area. I’d like to know if there are any other options available to me that work and if a transplant is something that should be done on someone with my hair loss level.

A: Both Propecia and Minoxidil definitely can work in the front of the scalp as long as there is some hair in the area. Although their mechanisms of action are different, both Propecia (finasteride) and Rogaine (minoxidil) act to thicken miniaturized hair wherever its location.

O, The Oprah Magazine has a feature on hair loss in women in their March 2010 issue.

Dr. Bernstein was consulted for the article and discussed female hair transplantation.

“Since female hair loss is often diffuse, only about 20 percent of female patients with thinning hair are candidates, says Robert Bernstein, MD, a New York City dermatologist who specializes in these surgeries.”
