Glossary Hair 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 if hair follicle miniaturization happens slowly and gradually over a few hair cycles then wouldn't that mean that to regain maximum or top thickness from treatment you would at least need 5-10 years?

in Research/Science 53 upvotes 10 months ago

Hair regrowth from treatments like finasteride, dutasteride, and minoxidil can take several years, with most visible results appearing within 1-2 years and potential improvements continuing up to 10 years. Consistency and patience are crucial for achieving maximum hair thickness, as hair miniaturization and regrowth are gradual processes.

community Scalp inflammation cleared after stopping "spoiled" milk - what about follicles,shedding?

4 upvotes 6 months ago

Switching milk brands cleared scalp inflammation and other symptoms, but hair shedding continues. The user hopes shedding will stop as hair cycles progress.

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.
