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 Anyone here have a lot of knowledge on hair follicle stem cells and progenitor cells for PP405?

in Chat 4 upvotes 6 months ago

Hair follicle stem cells remain in bald individuals, but progenitor cells do not, raising questions about hair regrowth claims by Pelage. PP405 is discussed as a potential treatment, with skepticism about its effectiveness compared to existing treatments like Minoxidil and Finasteride.

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

in Research/Science 1391 upvotes 10 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 Has anyone here actually undergone experimental (grey market) hair cell therapy/follicle cloning?

in Technology 6 upvotes 3 months ago

Hair cell therapy and follicle cloning are still in experimental stages, with treatments like hair multiplication and regenerative hair therapy being marketed but not yet proven to create unlimited new follicles. There is skepticism about the effectiveness and legitimacy of these treatments, with some considering them scams.
