This study observed that hair casts, seen in girls with tightly drawn hairstyles, may result from local circulatory disturbances and scalp inflammation.
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.
Finasteride can cause sexual side effects in less than 2% of men, but these often disappear over time, even if the treatment continues. Some users report persistent side effects, while others experience no issues or only temporary ones.
Clinical studies by Dr. Barghouthi and Dr. Bloxham indicate that Verteporfin, when used with FUE and FUT hair transplantation methods, shows promise in hair follicle regeneration and minimal scarring due to its ability to inhibit Yes-associated protein (YAP). Microneedling at depths of 3-3.5mm, combined with Verteporfin, could potentially reactivate dormant follicles, although the optimal dosage and application method are still under investigation. Concerns remain about the DHT sensitivity of regenerated follicles, highlighting the need for further research to optimize trauma levels and Verteporfin concentrations to achieve effective and scar-free hair regeneration.
Procapil is marketed as a natural hair loss treatment but lacks strong evidence and is industry-biased. Minoxidil and Finasteride are the only FDA-approved treatments for androgenetic alopecia.
