research Identification of hair shaft progenitors that create a niche for hair pigmentation

44 citations , April 2017 in “Genes & development”

This study identified hair shaft progenitors in the matrix that regulate hair growth and pigmentation by creating a niche dependent on stem cell factor, implicating KROX20+ cells in these processes.

Pre-Aggregation of Scalp Progenitor Dermal and Epidermal Stem Cells Activates the WNT Pathway and Promotes Hair Follicle Formation In Vitro and In Vivo Systems

research Pre-aggregation of scalp progenitor dermal and epidermal stem cells activates the WNT pathway and promotes hair follicle formation in in vitro and in vivo systems

17 citations , December 2019 in “Stem Cell Research & Therapy”

This study found that their system effectively supports the rapid formation of human hair follicle organoids, providing a platform for studying hair regeneration and drug screening.

research 840 Early and late matrix progenitors form the terminally differentiated cell layers of the hair follicle

April 2017 in “Journal of Investigative Dermatology”

This study found that hair follicle matrix progenitors differentiate into various layers asynchronously, with early progenitors forming the companion layer and later progenitors generating the inner root sheath and hair shaft.

The Dermal Papilla: An Instructive Niche for Epithelial Stem and Progenitor Cells in Development and Regeneration of the Hair Follicle

research The Dermal Papilla: An Instructive Niche for Epithelial Stem and Progenitor Cells in Development and Regeneration of the Hair Follicle

149 citations , July 2014 in “Cold Spring Harbor Perspectives in Medicine”

This article provides contact information for Bruce A. Morgan and features no new research findings.

The Regulatory Role of the Tetrapeptide AcSDKP in Skin and Hair Physiology and the Prevention of Aging Effects in These Tissues – A Potential Cosmetic Role

research The regulatory role of the tetrapeptide AcSDKP in skin and hair physiology and the prevention of ageing effects in these tissues – a potential cosmetic role

13 citations , March 2013 in “International Journal of Cosmetic Science”

This study reports that the tetrapeptide AcSDKP significantly promotes skin and hair health in vitro and ex vivo, suggesting it could be used cosmetically to counteract skin aging and hair loss.

community Why Fin/Dut Isn't Working for You GPR133: a new hairloss mechanism + Steroid Hair Loss Deep Dive

6 upvotes 1 month ago

Hair loss may be linked to the GPR133 receptor, independent of the androgen receptor pathway. Treatments like finasteride, dutasteride, minoxidil, RU58841, and KX-826 show varying results, with hair loss persisting due to high testosterone and GPR133's role.

community Solving Hair Loss with Research at MIT

in Research/Science 595 upvotes 1 year ago

Hair loss treatments like minoxidil, finasteride, TDM-105795, and PP405. MIT is hosting a hackathon to find innovative hair loss solutions.

community Prolactin the Cause of Hair Loss? ABS-201 the Cure?

29 upvotes 2 months ago

Prolactin may contribute to hair loss, but targeting its receptor won't cure androgenetic alopecia. ABS-201 could be a useful alternative or adjuvant therapy, similar to JAK inhibitors, but not more effective than HMI-115.

community Reminder: NURTURE those dormant hair follicles for as long as you can until PP405 comes out in 2028-2030

in Treatment 191 upvotes 9 months ago

PP405 is anticipated as a future treatment for dormant hair follicles, but its effectiveness and safety are uncertain. Current treatments include oral minoxidil and microneedling, with some avoiding finasteride due to side effects.

community My Theory Of Androgenic Alopecia

16 upvotes 9 months ago

Hair loss is linked to cellular physiology and the IGF-1 to TGF-B1 ratio, not just androgen sensitivity. The theory lacks evidence, while finasteride and minoxidil are effective treatments.

learn Cetirizine

How does cetirizine reduce inflammation linked to hair loss? Cetirizine is proposed to lower prostaglandin D2 and raise prostaglandin E2 around hair follicles; three small trials of a compounded 1% topical report modest increases in hair density and shaft thickness, with minoxidil doing better head-to-head. Topical cetirizine is off-label and unapproved for hair loss, and the evidence is too thin to call it effective or safe.
