User shared 1-year progress using finasteride 1mg and minoxidil, regaining hair density. Others praised the improvement and asked about side effects and additional treatments.
After 11 years on Finasteride, a user's hair is thinning again, suggesting hair may become more sensitive to DHT with age. They plan to introduce Dutasteride once a week, as they cannot tolerate Minoxidil.
DHT promotes beard growth but causes scalp hair loss due to inflammation and fibrosis. Treatments like finasteride and minoxidil help with hormonal signals and blood flow but don't address underlying inflammation.
Dutasteride takes 1-3 months to affect scalp DHT levels, not just a week. The prostate absorbs Dutasteride faster than the scalp due to different vascular networks and enzyme densities.
Hair loss is linked to cellular physiology and the IGF-1 to TGF-B1 ratio, not just androgen sensitivity. The theory lacks evidence, while finasteride and minoxidil are effective treatments.
