The amount of PRP hair treatments required is dependent on how severe the hair loss is, the current state of the hair, and the appearance you hope to achieve with the hair treatment. Nevertheless, the typical number of treatments is usually three sessions. After each session, the patients will wait for 4 to 6 weeks before taking the next treatment. After the third session, if more treatment sessions are required, the patients will be evaluated to determine the state of the hair condition before the commencement of more treatment.
