Dr. Robert M. Bernstein, pioneer of the follicular unit transplantation and follicular unit extraction hair transplant procedures, was selected as one of New York metropolitan area’s top physicians.

Of his being selected in the 2011 issue, Dr. Bernstein said, “My inclusion in the Best Doctors issue for the twelfth year in a row is a testament to the hard work and dedication of my staff, our consistently high quality of care, and our passion for treating patients who are struggling with hair loss.”

Research published in the January 2011 issue of the Journal of Clinical Investigation (Vol. 121, issue 1) reveals another breakthrough in the medical community’s understanding of the causes of — and possible cure for — androgenetic alopecia, or common male pattern baldness. The new research shows that the presence of a certain type of cell, called a progenitor cell, is significantly reduced in men with common baldness compared to men who are not bald. Read on for more details on this breakthrough.

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?

A: It is not true. Hair loss is caused by the miniaturizing effects of DHT on the hair follicle, not by blocked pores.

New developments in regenerative medicine, presented at the 18th Annual Scientific Meeting of the International Society for Hair Restoration (ISHRS) this past week, may have opened the possibility that a patient’s hair can be multiplied in his own scalp.

ACell, Inc., a company based in Columbia, Maryland, has developed and refined an Extracellular Matrix (ECM), a natural biological material that can be implanted at the site of an injury or damaged tissue in order to stimulate a unique healing response. The ECM stimulates the body’s own cells to form new tissue specific to that site (a process referred to as “Auto-cloning”).

The ACell MatriStem devices have had some preliminary success in allowing plucked hairs that were placed into recipient sites on the patient’s scalp to grow. Although this is a major breakthrough, significant work remains in order for hair multiplication to become a practical treatment for hair loss in men and women.

It is also anticipated that the regenerative properties of Extracellular Matrix will facilitate the healing of the incision in the donor area after a hair transplant. We are currently offering ACell to all patients undergoing follicular unit transplant procedures at no additional charge.

We are currently studying the use of ACell for scalp hair multiplication as well as the facilitation of wound healing in follicular unit transplantation procedures. We are also treating select patients outside the studies. If you are interested in participating, please give us a call.
