Ablative Fractional Resurfacing in Topical Drug Delivery: An Update and Outlook

The conversation is about using micro needling and PTD-DBM for hair loss treatment. The user applies PTD-DBM drops on weekdays and performs micro needling weekly.

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.

Minoxidil may not be effective due to low sulfotransferase activity, and the user considers adding tretinoin to the regimen. They are unsure about the timing and combination with microneedling.

Using tretinoin or tazarotene with minoxidil may eliminate the need for microneedling or dermastamping. Microneedling can enhance minoxidil's effects but may cause long-term scalp issues.

The conversation discusses applying a topical solution containing 0.01% tretinoin, 1.5% azelaic acid, and 5% minoxidil for hair loss. It is recommended to apply tretinoin at night and use sunscreen during the day to prevent skin damage.

A 43-year-old from Thailand shares progress after 1 month using topical finasteride, minoxidil, tretinoin cream, and weekly microneedling for diffused thinning. Users compliment his appearance and suggest he doesn't need treatment.
