Old people have less hair because their hair follicles don't regenerate as well, not because of fewer stem cells, and a protein called follistatin might help reactivate hair growth.
The conversation discusses difficulty in distinguishing between new hair growth and thinning hair at the temples after using microneedling and a rosemary peppermint topical for four weeks. The advice given is to wait a few months to see if the hairs grow out to determine their nature.
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.
A user's results after using finasteride (1.25mg/day) for one year, which included improvements to their hair and skin as well as some side effects such as decreased libido and watery semen. They also mentioned they stopped taking creatine around the same time.
A 32-year-old man has been treating his hair loss with daily oral finasteride (1.25g), twice-daily topical minoxidil, weekly ketoconazole 2% shampoo, and weekly microneedling for almost three months, with no side effects from finasteride. He started with a Hamilton Norwood scale rating of 5 and has seen improvement without experiencing pain by using a 0.8mm needle length for microneedling.
