Did you mean Vellus Follicles?

Glossary Vellus Follicles

small hair follicles producing fine, short, lightly pigmented hairs

Vellus follicles are small hair follicles that produce fine, short, and lightly pigmented hairs known as vellus hairs. These hairs cover most of the human body and are often referred to as "peach fuzz." Unlike terminal hairs, which are thicker and darker, vellus hairs play a minimal role in thermoregulation and are more prominent in children and women.

research Follicular miniaturization in female pattern hair loss: clinicopathological correlations

100 citations , June 2006 in “British Journal of Dermatology”

This study found that as hair loss severity increased in women with female pattern hair loss, the number of vellus follicles also rose, indicating miniaturization of terminal hair follicles.

research Hair removal using the long-pulsed ruby laser

community Confused why people are calling PP405 a cure...it never claimed to be able to undo miniaturization or revert vellus back to terminal hairs. It seems to be more of a growth stimulant like minoxidil.

in Research/Science 55 upvotes 1 year ago

PP405 is not a cure for hair loss but may reactivate dormant hair follicles, similar to minoxidil. It is unlikely to help with miniaturized or vellus hairs and is still in trial phases, with availability expected around 2030.

community Vellus/miniaturized hair - when are they really too miniaturized to regrow?

16 upvotes 3 weeks ago

Miniaturized hair can potentially regrow unless the follicle is destroyed, with treatments like finasteride, minoxidil, and lifestyle changes playing a significant role. Some users report success with additional treatments like estrogen, ketoconazole, and derma stamping, emphasizing the importance of routine and overall health.

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 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 It looks like Pelage are giving hints that PP405 is a game changer

in Chat 239 upvotes 5 months ago

PP405 is seen as a potential breakthrough for converting vellus hairs to terminal hairs, with users expressing both hope and skepticism. It is compared to treatments like minoxidil and finasteride, with discussions on side effects and marketing concerns.
