Multiphoton Microscopic Imaging of In Vivo Hair Mouse Skin Based on Two-Photon Excited Fluorescence and Second Harmonic Generation

Exosomes combined with fractional picosecond laser treatment were effective in treating androgenetic alopecia and promoting repigmentation in white hair patches. The role of exosomes in hair repigmentation, particularly in conditions like poliosis, is not well-studied.

RepliCel has purchased Trichoscience, and they have a video about hair multiplication. The conversation also mentions treatments like Minoxidil, finasteride, and RU58841.

The conversation discusses using USB microscopes for scalp photos and provides a link to an overview of trichoscopy. Treatments mentioned include Minoxidil, finasteride, and RU58841.

User discusses verteporfin for hair regrowth through "super microneedling" and preventing scarring. They mention a case of an old man regrowing hair after a head injury and suggest verteporfin could recreate this result.

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 gel of keratin microspheres promotes hair follicle growth, showing similar effectiveness to minoxidil in mice. The treatment activates hair growth pathways and reduces inflammation, with potential applications in drug delivery for hair-related disorders.
