research Cellular dynamics in the niche of infrequently dividing hair follicle stem cells in the mouse Mus musculus

October 2010 in “eCommons (Cornell University)”

This study found that mouse hair follicle stem cells use symmetric cell division for maintenance and fate determination, and identified Gata6 as a crucial factor for their differentiation.

research Dermal niche signaling and epidermal stem cells

January 2019 in “Advances in stem cells and their niches”

This review outlines the various fibroblast subsets in the skin dermis, their origins, and their influence on epidermal stem cell behavior, highlighting the role of the local dermal niche in stem cell plasticity.

research Molecular and Cellular Characterization of Avian Reticulate Scales Implies the Evo–Devo Novelty of Skin Appendages in Foot Sole

1 citations , July 2023 in “Journal of developmental biology”

In this study, researchers explored the molecular and cellular traits of avian reticulate scales, finding that they lack localized stem cell niches for regeneration, unlike other scale types, leading to repair but not regeneration after wounding.

research Dissecting the boundary of quiescence and activation of murine melanocyte stem cells in the hair follicle niche

April 2026 in “npj Regenerative Medicine”

This review discusses the processes of melanocyte stem cell quiescence and activation, focusing on their interaction with hair follicle stem cells, and highlights current research on hair graying mechanisms; it reports no new results.

research Repairing the lungs one breath at a time: How dedicated or facultative are you?

46 citations , December 2018 in “Genes & Development”

This review discusses lung regeneration and highlights the role of facultative stem/progenitor cells, but it reports no new findings and calls for further exploration of underlying mechanisms.

community Fully functional hair follicle regeneration through the rearrangement of stem cells and their niches

4 upvotes 11 years ago

Hair follicle regeneration through stem cell rearrangement is discussed, focusing on bioengineered cellular structures rather than traditional hair transplants. Treatments mentioned include Minoxidil, finasteride, and RU58841.

community PP405 Won’t Work: Follicle Is Miniaturized, Fibrosed, And Missing Key Support Cells

7 months ago

PP405 is ineffective for miniaturized, fibrosed hair follicles in androgenetic alopecia. AMP303 may activate hair follicle stem cells, but minoxidil and finasteride are still the main treatments.

community Everything you ever wanted to know about Pelage Pharma's PP405: how it works and what to expect

126 upvotes 2 months ago

PP405 may encourage earlier hair growth and slightly increase visible hair count but does not reverse hair follicle miniaturization in male pattern baldness. It does not address damage to the dermal papilla or broken Wnt signaling.

community My derm said they came up with a new serum that is better then fin? What’s y’all’s thoughts

7 months ago

A new serum claims to enhance hair regrowth by amplifying oxygen delivery, improving the effectiveness of treatments like exosomes and peptides. Users are skeptical, questioning its efficacy compared to established treatments like Minoxidil and Finasteride.

community A Theory on Why Microneedling Works

175 upvotes 6 years ago

Microneedling may enhance hair regrowth by transferring stem cells to dormant follicles, improving the effects of minoxidil. Users discuss using microneedling with needle lengths around 1.5mm to stimulate hair growth.

mTOR regulator and immunosuppressant used more recently for anti-aging and hair regrowth

signaling protein that, when suppressed, may grow hair by reducing inflammation and stem cell loss

learn Thymosin Beta 4

learn vitamin b2

How does Vitamin B2 support scalp circulation and cellular energy production? Vitamin B2 enhances scalp circulation and energy production by supporting cellular metabolism.

learn Folic acid

How does folic acid support hair follicle health and growth at a cellular level? Folate is required for the DNA synthesis that fast-dividing hair matrix cells depend on, and severe deficiency causes anemia—but no published trial has given folic acid to people with hair loss and measured the result, so a growth effect is a mechanism, not a finding.
