Microvascular Remodeling Strategy for Skin Rejuvenation Through Microenvironmental Reprogramming and Appendage Restoration

This post and conversation are about the molecular mechanisms triggered by microneedling, specifically its effects on inflammation, tissue remodeling, epithelial proliferation, differentiation, and collagen synthesis. The discussion highlights the potential benefits of microneedling for hair loss treatment.

The user has been using topical finasteride and minoxidil for two years with decent regrowth and recently added microneedling to their routine. They are questioning if the small hairs observed are new regrowth from microneedling or just vellus or miniaturized hairs.

Microneedling at depths greater than 0.6 mm may damage miniaturized hair follicles, with 0.5 mm showing better results for hair regrowth. Combining microneedling with minoxidil enhances absorption, but caution is advised to avoid damaging follicles.

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.

The user has been using Minoxidil, Finasteride, and biotin for hair regrowth over four years, recently adding microneedling with a derma pen. They are considering increasing microneedling frequency, trying minoxidil pills, and possibly using Dutasteride for better results.

The conversation discusses using daily microneedling at 0.25mm and red light therapy to enhance hair regrowth, especially when traditional treatments like finasteride and minoxidil become less effective. The combination is said to improve hair density and thickness, with red light therapy being more cosmetic, while microneedling is essential for challenging areas.
