Glossary Matrix Cells

specialized cells that generate new hair growth

Matrix cells are specialized cells located at the base of the hair follicle, within the hair bulb. These cells are responsible for producing the hair shaft and the inner root sheath through rapid cell division and differentiation. Essentially, they are the "building blocks" that generate new hair growth.

research Dihydrotestosterone-Inducible IL-6 Inhibits Elongation of Human Hair Shafts by Suppressing Matrix Cell Proliferation and Promotes Regression of Hair Follicles in Mice

173 citations , September 2011 in “Journal of Investigative Dermatology”

IL-6 contributes to hair loss by shortening the growth phase and causing hair follicles to regress.

31 citations , December 1991 in “Annals of the New York Academy of Sciences”

This study found that distinct keratin profiles enabled the evaluation of epithelial differentiation in human hair follicles, with mesenchymal cells playing a critical role in epidermoid differentiation of follicular cells.

research Extracellular Matrix as a Regulator of Epidermal Stem Cell Fate

57 citations , March 2018 in “International Journal of Molecular Sciences”

This review highlights recent advances in understanding how the extracellular matrix regulates epidermal stem cell fate, emphasizing the importance of the hair follicle stem cell niche, but reports no new empirical findings.

research Stem cell factor combined with matrix proteins promotes attachment and migration of amelanotic melanocyte from human follicle hair

January 2006 in “Linchuang pifuke zazhi”

This study found that stem cell factor combined with fibronectin and type IV collagen promotes migration of amelanotic melanocytes, which may help explain their movement during vitiligo repigmentation.

research Hair matrix germinative epidermal cells confer follicle-inducing capabilities on dermal sheath and high passage papilla cells

61 citations , October 1996 in “Development”

This study found that combining adult germinative epidermal cells with non-inductive dermal cells can stimulate hair follicle neogenesis, effectively altering the cells' status to enhance induction.

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.

community My Theory Of Androgenic Alopecia

16 upvotes 10 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.

community Why you can still look forward to PP405 and JXL-069

22 upvotes 1 month ago

PP405 and JXL-069 are the same compound, but users experienced no results due to flawed application methods. The topical gel formulation of PP405 is designed to target hair follicle stem cells effectively, unlike liquid solutions that fail to penetrate deeply.

community Prevention of age-related beard graying in humans by the topical application of Eriodictyon angustifolium extract

5 upvotes 4 years ago

Topical application of Eriodictyon angustifolium extract can prevent and reverse age-related beard graying and darken gray hair by increasing melanin production. Sterubin, a component of the extract, also promotes hair pigmentation and protects cells from DNA damage.

community How ET-02 Works. Also no proof that it's better than Minoxidil. At least for now.

44 upvotes 1 year ago

ET-02, a PAI-1 inhibitor, is not proven to be more effective than Minoxidil for hair loss. Other treatments like finasteride, dutasteride, PP405, and AMP-303 are also discussed, focusing on cellular senescence and oxidative stress.

community PP405 Won't Work Long Term: Hair Follicle Damage Due to Abuse of the ISR System

67 upvotes 11 months ago

PP405 may damage hair follicles if used long-term, suggesting cycling might be necessary. Combining it with finasteride could help maintain hair growth.
