Hairfollicles don't truly die but become severely miniaturized. Treatments like finasteride, dutasteride, and minoxidil can help restore hair by providing nutrients and reducing harmful effects on hair roots.
Hairfollicles can be dormant and potentially revived with treatments like finasteride and minoxidil, but irreversible loss occurs if certain structures are destroyed. Early intervention is more effective, and additional methods like microneedling may help.
Minoxidil can prevent hairfollicle miniaturization, not just stimulate hair growth. Finasteride and dutasteride don't work for everyone, suggesting DHT may not be the sole cause of hair loss; hair loss could be due to multiple factors, including autoimmune conditions.
Stress can lead to hair loss by affecting hair-follicle stem cells, and this loss is harder to recover from if one has male pattern baldness (MPB). Treatments like finasteride and minoxidil are used to address hair loss, but stress-related hair loss differs from androgenic alopecia.
HairClone is developing cell replacement treatments to rejuvenate and generate hairfollicles, and has launched a crowdfunding campaign. A user expressed skepticism about the need for crowdfunding.
