Long term Finasteride users and whether or not they have noticed improvements after two years of use, with other treatments such as Minoxidil and dermarolling also discussed. Some replies suggest that improvement is possible even beyond the two year mark while others caution against believing studies backed by the Post-Finasteride Foundation.
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.
How Finasteride and Dutasteride help reduce hair loss by reducing the amount of DHT in scalp areas, as well as discussing factors such as sensitivity to DHT, 5α-reductase expression in different parts of the hair follicle, and scalp tension.
Caffeine intake may increase DHT levels, but its impact on hair loss is minimal compared to genetic factors. Excessive caffeine can cause health issues, and its effects on hair loss are not directly applicable to humans based on rat studies.
Safflower oil is suggested as an alternative to minoxidil for hair growth, with benefits including scalp conditioning and hair strength enhancement. Studies indicate it may also reverse scalp dermatitis, alopecia, and prevent premature grayness.
