community How is it possible for someone to be a non responder to ORAL minoxidil?

in Minoxidil 66 upvotes 2 years ago

Some individuals do not respond to oral minoxidil for hair loss, despite it generally working by improving blood flow to hair follicles. Factors like metabolism, drug interactions, and individual variations in the drug's activation may influence its effectiveness.

1 upvotes 1 month ago

A 31-year-old is concerned about rapid hair loss before their wedding in 9 weeks, currently using 1mg finasteride and 3.75mg minoxidil daily. Suggestions include accepting the current situation, using hair powders for density, and considering dutasteride after the wedding.

community Trying to understand severe shedding and progressive density loss after a successful hair transplant

8 upvotes 3 weeks ago

The user is experiencing severe shedding and progressive hair density loss after a successful hair transplant, despite using finasteride, minoxidil, microneedling, and scalp treatments. Suggestions include trying stronger treatments like oral dutasteride, topical RU58841, and higher doses of oral minoxidil.

community Does regrowth always start as thin hairs? Do hairs thicken as they grow or do they need to shed and then come back to get thicker?

in Chat 32 upvotes 1 year ago

Hair regrowth can start as thin hairs that may thicken over time, with treatments like finasteride and minoxidil showing varied results. Some users report initial shedding followed by thicker regrowth, while others experience mixed outcomes in different areas.

community 1yr on fin and min. I guess im not bald anymore.

204 upvotes 7 months ago

learn Finasteride

Does hair strand thickness decrease in men with androgenic alopecia? Can finasteride help restore it? Androgenic alopecia thins hair strands by miniaturizing follicles. The pivotal finasteride trials (1,553 men, 1 mg/day, two years) report increased hair counts and improved assessed appearance, but they measured density, not the diameter of individual strands, so the effect on thickness itself is not established.

learn Fluridil

Can daily Fluridil application stop hair follicle miniaturization? The single published fluridil trial (43 men; placebo-controlled for 3 months, then all on fluridil to 9 months) reported more hairs in the growth phase, but it never measured follicle diameter and has not been replicated — so whether daily use stops miniaturization is unproven, and community users describe stabilization rather than regrowth.
