This review highlights novel drug delivery systems for alopecia that enhance localization in the pilosebaceous unit, reduce systemic exposure, and support sustained drug release, with a focus on optimized follicular carriers ranging from 100-300 nm for improved drug residence compared to conventional methods.
This study found that compounds from *Tectona grandis* leaves showed moderate inhibition of steroid 5α-reductase, a factor in androgenetic alopecia, and exhibited anti-inflammatory properties by inhibiting nitric oxide and pro-inflammatory cytokines IL-1β and IL-6 in vitro, suggesting potential dual-action benefits for AGA management.
The user is using minoxidil, finasteride, dermarolling, and other treatments for hair regrowth, showing promising results in the temple area. Despite some skepticism, there is optimism about potential improvement.
A 23-year-old user shares their hair regrowth journey, questioning if genetics or other factors are at play. They use Rogaine, finasteride, vitamin B12, biotin, Thera M Plus, and derma stamping, and seek advice on their regimen and hairgrowthpatterns.
Unusual hairgrowth can occur in unexpected areas, possibly due to topical treatments like Minoxidil. Such hair may appear suddenly and is often unrelated to typical hairline patterns.
The user is experiencing a strange hair loss pattern despite using dutasteride for 3 years and minoxidil with tretinoin for 1.5 years. They recently added microneedling and are considering a scalp biopsy to understand the cause.
The user noticed small circular hairless spots after a buzz cut and has been using finasteride, dutasteride, and oral minoxidil for hair loss. They are experiencing continuous shedding and thinning, and it is suggested they consult a dermatologist for a scalp examination and possible biopsy to determine if it's alopecia areata or androgenetic alopecia.
