Doctors are testing verteporfin topically for healing and potential regeneration after transplants. The user is asking how it is formulated for topical use, such as if it's mixed with a carrier gel.

The post discusses a theory that hair regrowth after transplant is due to the angiogenesis process (new blood vessels forming), not because the transplanted hair is unaffected by DHT. The responses highlight the established belief in 'donor dominance' (the importance of the hair's origin in transplantation) and skepticism about the new theory.

The conversation discusses hair loss and treatments, with users suggesting the original poster's hair has receded despite using a dermaroller and RU58841 for two months. Many recommend starting finasteride and minoxidil for better results.

Daily microneedling at 0.25mm before applying minoxidil is debated, with some suggesting weekly microneedling is safer and more effective. Concerns include potential skin damage and systemic absorption, while alternatives like tretinoin are considered safer for enhancing minoxidil absorption.

A user experienced significant hair shedding and thinning 10 months post-hair transplant despite using minoxidil and topical finasteride. They are considering switching to oral finasteride or dutasteride and are also dealing with scalp conditions like seborrheic dermatitis.
