Most patients require a series of PRP sessions to achieve noticeable improvements. A common treatment plan includes 3–6 initial sessions spaced 4 weeks apart. This allows the scalp to receive repeated doses of concentrated growth factors, gradually stimulating hair follicles and improving density.
After the initial series, maintenance sessions every 3–6 months are often recommended, as hair follicles continue to respond positively to ongoing stimulation. Results vary between individuals based on hair-loss severity, scalp condition, lifestyle factors and overall health. Some patients notice improved texture and reduced shedding early on, while visible thickening may take several months. Consistency is key — PRP works best as a repeated therapy, not a one-time treatment.
