Hair PRP means injecting into the scalp a platelet-rich plasma prepared from your own blood. The growth factors it releases restart the hair cycle, thicken the shaft and slow shedding. But PRP is not a treatment for every kind of hair loss: it is discussed after a diagnosis. In Marrakech, Dr Sara Zahid, dermatologist in Guéliz, offers it mostly for early androgenetic alopecia, alongside a medical treatment. Before any session she looks for the cause of the loss, because a deficiency, alopecia areata and hereditary balding are not treated the same way.
Hair loss can come from hereditary balding (androgenetic alopecia), shedding after a shock, a delivery or a deficiency, a thyroid disease, alopecia areata, scalp inflammation or scarring alopecia. Examination of the scalp, with trichoscopy, and sometimes blood tests, comes before any treatment. PRP given for the wrong cause would be a useless treatment.
The concentrated platelets are injected into the scalp, at the level of the follicles. The growth factors they release stimulate weakened follicles, prolong the growth phase of the hair and gradually thicken the shaft. PRP does not create new follicles: it helps those that are still there.
It is mainly indicated in early androgenetic alopecia, when density is falling but follicles are still active, and as a complement to a medical treatment. It is less useful when the area has been bare for a long time, and it does not treat scarring alopecia. For alopecia areata, other treatments are preferable.
The blood draw is followed by preparation of the plasma, then multiple injections into the scalp. The session lasts about three quarters of an hour. A numbing cream or cooling limits discomfort. There is no social downtime: small redness or a tender scalp are possible for a few hours.
Usually three sessions a month apart, then maintenance. First results are seen from the third session: less shedding, thicker hair. The effect is neither immediate nor permanent: it is maintained, and the associated medical treatment keeps its role.
It does not replace a long-term treatment for hereditary balding, nor the correction of a deficiency or disease at the root. It does not regrow hair on an area that has been bare for a long time. It can accompany a hair transplant but does not take its place.
PRP is avoided during pregnancy and breastfeeding, with a scalp infection, blood disease or clotting disorders. Mention blood-thinning treatments. Side effects are modest: mild pain, swelling, small bruises.
