Fat Cell Discovery An “Important Step” In Understanding Hair Loss

September 2nd, 2011

In what might be another illuminating discovery on the inner-workings of hair growth, Yale University scientists have discovered that cells from the fat layer in the skin of mice contribute to the stimulation of hair follicles.

Dr. Bernstein, who was interviewed for the ABC News article, called the findings, “An interesting development in understanding why millions of people go bald.” Read more by viewing the full post.

Researchers “Accidentally” Reverse Hair Loss Caused by Stress

March 7th, 2011

Sometimes an “accident” in the laboratory can lead to a remarkable breakthrough. Penicillin, Botox, Viagra, and Minoxidil — the active ingredient in Rogaine — were all unintended discoveries that led to treatments for a variety of conditions. A similar twist of fate, this time by researchers at UCLA, could lead scientists to a new hair loss treatment.

Does Sebum Cause Hair Loss By Blocking Pores On Scalp?

November 29th, 2010

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.

Dr. Christiano at Columbia University Identifies APCDD1, A Newly Discovered Gene Associated With Hair Loss

April 14th, 2010

Dr. Angela Christiano of Columbia University in New York and a team of scientific researchers, have identified a new gene involved in hair growth. Their discovery may affect the direction of future research for hair loss and the diagnosis and ultimate prevention of male pattern baldness.

The condition, which leads to thinning hair, is called hereditary hypotrichosis simplex. Through the study of families in Pakistan and Italy who suffer from this condition, the team was able to identify a mutation of the APCDD1 gene located in chromosome 18. This chromosome has been linked to other causes of hair loss.

Causes

July 28th, 2009

It is caused by the effects of the male hormone dihydrotestosterone (DHT) on genetically susceptible scalp hair follicles. This sensitivity to DHT is present mainly in hair follicles that [...]
