Platelet-rich plasma is obtained by extracting a small amount of blood from the patient’s arm and then separating the plasma fractions by centrifugation. At Delarra we use a closed-circuit technique, as required by health legislation for the maximum safety of our patients. Once the plasma has been extracted, microinjections are made into the scalp (with very little discomfort) allowing the patient to resume normal activity immediately. When injected into the scalp, the vascularisation and regeneration of the hair follicle is activated in a very important way. Platelet-rich plasma is very useful for slowing down hair loss, activating hair growth and helping hair thickening.
