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.

community Who won’t respond to minoxidil? (Studies)

in Research/Science 34 upvotes 5 months ago

Minoxidil's effectiveness varies due to differences in sulfotransferase enzyme levels in the scalp, affecting people with conditions like ASD, liver disease, and androgenic alopecia. Treatments like topical tretinoin, microneedling, and using minoxidil sulfate instead of regular minoxidil can improve results for those with low enzyme levels.

community TWIST-1 and the cure: Is it really that easy?

in Research/Science 283 upvotes 4 years ago

TWIST-1 gene's role in hair loss and potential as a treatment target. Inhibiting TWIST-1 may prolong hair growth and reduce hair follicle sensitivity to DHT.

community will pp405 be able to bring my lost temple area back to the game?

in Research/Science 10 upvotes 4 months ago

A user is concerned about hair loss in the temple area despite using Minoxidil and finasteride for 10 months and is curious if PP405 can help. Responses indicate uncertainty about PP405's effectiveness, with some optimism about future treatments and AI speeding up drug discovery, but emphasize waiting for clinical trial results.

community PP405 Won't Work Long Term: Hair Follicle Damage Due to Abuse of the ISR System

in Research/Science 67 upvotes 10 months ago

PP405 may damage hair follicles if used long-term, suggesting cycling might be necessary. Combining it with finasteride could help maintain hair growth.
