Pig skin is a good substitute for human skin to measure drug absorption, but differences in skin structure and enzymes across species must be considered.
PP405 is a potential hair loss treatment that inhibits mitochondrial pyruvate carriers, increasing lactate dehydrogenase activity and stimulating hair follicle stem cells. In a phase 1 trial, 31% of participants showed over 20% hair density increase with PP405 treatment.
Peptides like TB500, KPV, GHK-CU, and BPC-157 are overhyped for hair growth with limited proven effectiveness in humans. Combining peptides with delivery methods like iontophoresis and sonophoresis shows promise, but many claims remain unproven.
The conversation discusses hair regrowth using dissolvable microneedles loaded with rapamycin and epigallocatechin gallate nanoparticles. Specific treatments mentioned include Minoxidil, finasteride, and RU58841.
The conversation discusses the best vehicle for topical dutasteride, comparing Trichosol, Transcutol, and a gel version. It also mentions using Transcutol with ethanol to enhance transdermal delivery of Bimatoprost.
The user is experiencing ongoing hair loss despite using a comprehensive treatment regimen including dutasteride, oral minoxidil, cyproterone acetate, transdermal estradiol, and topical bicalutamide. They suspect cyproterone acetate may be worsening their hair loss and are considering switching to injection monotherapy.
