Divergent Proliferation Patterns of Distinct Human Hair Follicle Epithelial Progenitor Niches In Situ and Their Differential Responsiveness to Prostaglandin D2

research Divergent proliferation patterns of distinct human hair follicle epithelial progenitor niches in situ and their differential responsiveness to prostaglandin D2

21 citations , November 2017 in “Scientific Reports”

This study found that prostaglandin D2 reduced proliferation in bulge resident K15+ stem cells but not in other K15+ progenitor cells, suggesting differential impacts on hair follicle stem cell niches.

research 503 A new chemosensory control of human hair growth: Olfactory receptor OR10J1 stimulation promotes scalp hair follicle growth and progenitor cell generation ex vivo

November 2024 in “Journal of Investigative Dermatology”

Stimulating OR10J1 can promote hair growth and may help treat hair loss.

Hair loss caused by genetics and hormones; more research needed for treatments.

Therapeutic Potential of Patient iPSC-Derived Melanocytes in Autologous Transplantation

research Therapeutic Potential of Patient iPSC-Derived iMelanocytes in Autologous Transplantation

31 citations , April 2019 in “Cell reports”

This study found that human iPSC-derived melanocytes from vitiligo patients successfully integrated into mouse hair follicles and epidermis, demonstrating potential for personalized therapy for depigmentation.

research Mapping the expression of epithelial hair follicle stem cell‐related transcription factors LHX2 and SOX9 in the human hair follicle

33 citations , March 2015 in “Experimental Dermatology”

In this study, LHX2 and SOX9 were found to mark distinct epithelial progenitor cell populations within human hair follicles, suggesting roles in maintaining the hair follicle epithelium.

community Microneedling depth. Does one length fit all areas of the scalp? Maybe not.

55 upvotes 4 years ago

Microneedling depth should be customized based on hair type and scalp area, with many users finding 0.5-0.6mm effective for miniaturized hairs to avoid damage. Users report varying pain levels and results, with some preferring shorter needle lengths and others using longer ones like 1.75mm for scalp health and density improvement.

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.
