community Difference between my hair wet and dry literally an hour apart

in Finasteride/Dutasteride 757 upvotes 1 year ago

The conversation is about hair loss treatments, focusing on minoxidil and finasteride, with suggestions for microneedling and dermarolling to improve hair thickness. The original poster has used minoxidil for four years and finasteride for over a year but is exploring additional options for better results.

community Can the ingredients in a sebum-regulating shampoo induce hair diameter reduction?

2 upvotes 1 year ago

A user experienced hair thinning and scalp issues after using a sebum-regulating shampoo and perm treatments. They are advised to consider potential allergies, try a simple shampoo, and research treatments like finasteride for possible male pattern baldness.

community "When comparing 5% minoxidil with 0.60 mm or 1.20 mm needle lengths, Faghihi et al. found that 0.60 mm needle lengths led to significant hair count and diameter increases versus 5% minoxidil, whereas 1.20 mm needle lengths only saw hair count increases versus 5% minoxidil"

in Research/Science 60 upvotes 2 years ago

Microneedling with 0.6 mm needles combined with 5% minoxidil is more effective for hair count and thickness than minoxidil alone or with 1.2 mm needles. Biweekly microneedling at 0.6 mm depth is recommended for better results in treating androgenetic alopecia.

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, 9 months, double-blind and placebo-controlled) 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.
