Dr. Bernstein Interviewed for ‘Cosmetic Town’ Article on Benefits of Rogaine for Male Pattern Baldness

Cosmetic Town

Dr. Bernstein contributed to an article published on the cosmetic surgery portal “Cosmetic Town” about the benefits and usage of Rogaine® (minoxidil) hair loss medication.

The article also discusses the recommended dosage of Rogaine, a comparison of Rogaine and Propecia, when a patient can expect to see results of medical treatment of hair loss, and other related topics.

How Does Minoxidil Work? A Review Of Recent Research

Since 1993, minoxidil has been the most successful topical treatment for hair loss in both men and women, yet its exact mechanism of action remains unknown.

A 2004 review of minoxidil’s possible mechanisms of action (A.G. Messenger & J. Rundegren, 2004) suggests that the best evidence supports the idea that minoxidil causes hair follicles in the later phases of their resting phase (telogen) to shift prematurely into an active growth phase (anagen) sooner than they otherwise would; this causes rapid increase in hair growth. They also found good evidence that minoxidil works to thicken the hair by increasing hair diameter.

While minoxidil’s effects on other critical factors known to affect hair growth — such as cell proliferation, collagen synthesis, vascular endothelial growth factor and prostaglandin synthesis — remain uncertain, more recent research has found evidence that it may also suppress the androgen-androgen receptor responsible for androgenetic alopecia (Cheng-Lung Hsu, Jai-Shin Liu,An-Chi Lin, Chih-Hsun Yang, Wen-Hung Chung, & Wen-Guey Wu, 2014).

Understanding minoxidil’s exact mechanism of action remains today an important line of research both for the development of better hair loss treatments and for a better understanding of the biology of hair growth.

What is Latest Information on Persistent Side Effects from Finasteride?

Q: I have heard that side effects from finasteride can persist even after stopping the medication. What is the most current information on this issue? — S.V., Short Hills, N.J.

A: For the past two years I have been on the ISHRS’s Task Force on Finasteride Adverse Events and struggling to make sense of this issue. There seems to be a disconnect between the relatively low incidence of side effects that we, as physicians, see in our practices, what published controlled studies have shown, and what is now being reported on the internet. For example, a 2012 study by Sato of 3,177 Japanese men published the Journal of Dermatology, showed a 0.7% incidence of adverse reactions to finasteride 1% and no persistent side effects after stopping the medication.

That said, there has been a recent increase in anecdotal reports of side effects from finasteride as well as reports of persistent side effects after the medication has been discontinued (referred to as “Post-finasteride Syndrome”).

Research Points To Vitamin D Receptors As Possible Clue To Reversing Hair Loss

Could it be that Vitamin D is the cure for baldness that scientists have been looking for all these years? New research on Vitamin D, and its receptors in hair follicles, has taken us down a previously untrodden path that could, potentially, lead to new medical treatments for hair loss.

The Vitamin D receptor was previously known to stimulate hair follicles, which were in the dormant phase of hair growth, to grow hair when activated. The research into Vitamin D and its effect on hair and skin, centers around this receptor.

Sato Finasteride Study Points to Long-term Safety, Efficacy in Use of Propecia

Led by Dr. A. Sato, a Japanese team of medical researchers published the largest finasteride study ever performed, “Evaluation of efficacy and safety of finasteride 1mg in 3,177 Japanese men with androgenetic alopecia.” It investigated the effects of finasteride over a 3 1/2 year period in men with androgenetic alopecia, or common baldness.

The study found that patients who had experienced hair loss for an extended period of time and were treated with finasteride exhibited notable hair growth. While a fairly small proportion of patients with a hair loss duration over 10 years exhibited “greatly increased” growth, 85% of patients with hair loss duration of more than 15 years experienced “moderate” or “slightly increased” growth. Physicians have thought that people with advanced hair loss do not respond as well as patients in the early stages of hair loss. However, in light of the results of this study, that determination should be reconsidered. Continue reading this article.

Before and After Photos of Medical Therapy Look Too Good To Be True!

Q: Are the “result” photos from taking Propecia and using Rogaine legitimate? Some of the after photos look too good to be real and a few patients looked like they combed their hair to look like they had more coverage. — T.Y., Darien, Connecticut

A: The before and after photos of patients using Propecia and Rogaine are my patients. All photos on our website are un-retouched. Often, when patients have a good response to medical therapy, they have more flexibility in how they can groom and style their hair. This is reflected in the photos.
