GlossaryHair Follicle Cells

specialized cells responsible for hair growth and regeneration

Hair follicle cells, also known as follicular cells, are specialized cells located within the hair follicle, the skin structure responsible for hair growth. These cells play a crucial role in the hair growth cycle, including the phases of growth (anagen), regression (catagen), and rest (telogen). They are involved in the production of keratin, the protein that makes up hair, and are essential for the regeneration and repair of hair.

community Do hair follicles dies or are dormant ?

in Finasteride/Dutasteride 92 upvotes 1 year ago

Hair follicles can be dormant and potentially revived with treatments like finasteride and minoxidil, but irreversible loss occurs if certain structures are destroyed. Early intervention is more effective, and additional methods like microneedling may help.

community "Hair Follicle Stem Cells are quiescent 99% of the time and permanently reside in the hair follicle"

in Research/Science 1391 upvotes 11 months ago

Hair follicles are mostly dormant but can be reactivated with treatments like minoxidil, finasteride, and microneedling. A new drug, PP405, shows promise for hair regrowth but may not be available until 2027-2028.

community A hair model who does beauty ads and has 3 million followers claims he went from almost a Norwood 3 to a perfect hairline in 8 months on only Minoxidil and Rosemary oil. Curious, what are people’s thoughts?

in Chat 3 years ago

This conversation discusses the results of a model who claims he went from almost a Norwood 3 to a perfect hairline in 8 months using only Minoxidil and Rosemary oil. The replies suggest that this could be realistic but long-term results would require additional treatments like finasteride or other medications to prevent further hair loss.

community How far away are we from scalp/hair follicle cloning for an essentially unlimited transplant supply? And would prior transplants affect eligibility?

in Research/Science 7 upvotes 5 months ago

Hair/scalp cloning for unlimited transplants is likely a decade away, with prior transplants not significantly affecting future options. Advances in AI and research in wound-induced hair neogenesis are promising, but infrastructure and technology constraints remain challenges.

community Baldness Breakthrough: microRNA Stimulates Hair Growth in Aging Follicles

in Technology 318 upvotes 3 years ago

miR-205, a tiny RNA, can stimulate hair growth by softening aging hair follicle stem cells in mice. Future tests aim to see if this can work in humans.
