PRP treatment begins with a small blood draw, processed in a centrifuge to concentrate the platelet-rich plasma before it's reintroduced into the skin or scalp. Exosome therapy, by contrast, uses a pre-prepared formulation applied topically or through fine injection, often following microneedling to enhance absorption. Both treatments are performed under strict sterile conditions, with sessions typically completed within 45 minutes to an hour. Your specialist will recommend the treatment, or sequence of treatments, best suited to your skin or hair goals during your consultation.
