PRP, Mesotherapy, and Botulinum Toxin for Non-Scarring Hair Loss

The lecture discusses the use of Platelet Rich Plasma (PRP), mesotherapy, and botulinum toxin for treating non-scarring hair loss, particularly androgenetic alopecia and alopecia areata. PRP, derived from a patient's own blood, is rich in growth factors that may enhance hair density by promoting follicle health. Evidence suggests it can lead to a significant increase in hair density, especially with a monthly injection schedule during the initial treatment phase. Combining PRP with minoxidil may also enhance outcomes. For alopecia areata, PRP appears potentially more effective than triamcinolone, showing promise in prolonging remission periods despite being cost-prohibitive and not covered by insurance. Mesotherapy, using systemic agents like dutasteride and minoxidil, offers targeted drug delivery options, though dutasteride is preferred due to its longer half-life. Common side effects are generally mild and resolve quickly. Lastly, the utility of botulinum toxin, while showing some positive outcomes, remains inconclusive and requires standardized protocols for effective application. Overall, more long-term studies are needed to determine optimal frequencies and efficacy of these therapies.
