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.
ET-02, a PAI-1 inhibitor, is not proven to be more effective than Minoxidil for hair loss. Other treatments like finasteride, dutasteride, PP405, and AMP-303 are also discussed, focusing on cellular senescence and oxidative stress.
PP405 may damage hair follicles if used long-term, suggesting cycling might be necessary. Combining it with finasteride could help maintain hair growth.
HairClone is developing cell replacement treatments to rejuvenate and generate hair follicles, and has launched a crowdfunding campaign. A user expressed skepticism about the need for crowdfunding.
Minoxidil's effectiveness is limited by the need for sulfation and proper transport to hair follicles, with tretinoin potentially enhancing its effects by promoting enzyme activity and keratinocyte differentiation. Tretinoin may improve minoxidil's response by boosting the expression of necessary enzymes and transporters.
