The Role of the SLC39A Family of Zinc Transporters in Zinc Homeostasis in Skin

Topical finasteride results in plasma levels 100 times lower than oral finasteride, potentially reducing systemic side effects. Users report similar efficacy with fewer side effects, suggesting a preference for topical application.

Creatine is reported by many to increase hair loss, though no scientific evidence supports this. Some use finasteride and minoxidil to manage hair loss, while others avoid creatine due to personal experiences.

The treatment for androgenetic alopecia involves using finasteride and minoxidil with intense exercise and cold exposure to boost metabolism and reduce androgenic effects, potentially leading to hair regrowth. This approach may activate biological pathways for improved hair and overall health.

Oral minoxidil can still work without the SULT1A1 enzyme because the liver has enough of it, but its effectiveness on the scalp depends on transporters. Oral minoxidil generally does not affect blood pressure at low doses.

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.

PP405 may damage hair follicles if used long-term, suggesting cycling might be necessary. Combining it with finasteride could help maintain hair growth.
