Androgenetic Alopecia: Modeling Progression and Regrowth

April 2016 in “ Experimental Dermatology ”

Rodney Sinclair

Studysummary This commentary discusses the mechanisms of progression and potential regrowth in androgenetic alopecia, indicating that the initiation of anagen in kenogen follicles is more critical for hair density improvement than reversing follicle miniaturization.

7 / 7 results

research Hair Regrowth in Male and Female Pattern Hair Loss Does Not Involve the Conversion of Vellus Hair to Terminal Hair

14 citations , January 2016 in “Experimental Dermatology”

This analysis concluded that hair regrowth in male and female pattern hair loss treatments did not involve converting vellus hairs into terminal hairs, suggesting a reactivation of dormant non-vellus follicles instead.

research Destruction of the Arrector Pili Muscle and Fat Infiltration in Androgenic Alopecia

35 citations , March 2014 in “British Journal of Dermatology”

This study found that in androgenic alopecia, the arrector pili muscle degenerates and is replaced by fat, unlike in normal skin or telogen effluvium.

Miniaturized Hairs Maintain Contact With the Arrector Pili Muscle in Alopecia Areata but Not in Androgenetic Alopecia: A Model for Reversible Miniaturization and Potential for Hair Regrowth

research Miniaturized Hairs Maintain Contact With the Arrector Pili Muscle in Alopecia Areata but Not in Androgenetic Alopecia: A Model for Reversible Miniaturization and Potential for Hair Regrowth

22 citations , July 2012 in “International Journal of Trichology”

This study found that loss of contact between the arrector pili muscle and the hair follicle bulge may explain why hair loss in male and female pattern baldness is largely irreversible, unlike in alopecia areata.

The Ludwig Pattern of Androgenetic Alopecia Is Due to a Hierarchy of Androgen Sensitivity Within Follicular Units That Leads to Selective Miniaturization and a Reduction in the Number of Terminal Hairs Per Follicular Unit

research The Ludwig Pattern of Androgenetic Alopecia Is Due to a Hierarchy of Androgen Sensitivity Within Follicular Units That Leads to Selective Miniaturization and a Reduction in the Number of Terminal Hairs Per Follicular Unit

47 citations , September 2008 in “British Journal of Dermatology”

This study found that women with androgenetic alopecia experience diffuse hair loss due to a decrease in terminal hairs and an increase in vellus hairs per follicular unit.

research The Lack of Significant Changes in Scalp Hair Follicle Density With Advancing Age

33 citations , April 2005 in “British Journal of Dermatology”

This study found that age and follicular miniaturization were extremely weak predictors of total hair count in women with hair loss.

Measuring Reversal of Hair Miniaturization in Androgenetic Alopecia by Follicular Counts in Horizontal Sections of Serial Scalp Biopsies: Results of Finasteride 1mg Treatment of Men and Postmenopausal Women

research Measuring Reversal of Hair Miniaturization in Androgenetic Alopecia by Follicular Counts in Horizontal Sections of Serial Scalp Biopsies: Results of Finasteride 1mg Treatment of Men and Postmenopausal Women

145 citations , December 1999 in “Journal of Investigative Dermatology Symposium Proceedings”

Finasteride 1mg helps reverse hair miniaturization in men and postmenopausal women.

research Fortnightly Review: Male Pattern Androgenetic Alopecia

179 citations , September 1998 in “BMJ”

This article reviews the pathogenesis, genetic basis, and recent treatment breakthroughs for androgenetic alopecia but reports no new clinical findings.
