Hair loss treatments PRP grow your hair back MelbourneThe running theory as platelet-rich plasma (PRP) applies to hair regrowth is that the PRP’s growth factors, released by platelets, act on stem cells in the bottom of the hair follicle, stimulating the development of new follicles and promoting blood flow. In some people, a series of PRP injections can stimulate hair growth.

Androgenic alopecia – male pattern baldness – is a common type of hair loss that occurs in both men and women. Over the years many hair loss treatments have been trialled, but none have been as simple or easy as anyone might like. The latest advancement in the hair regrowth market is platelet-rich plasma (PRP), which is not a product per se, but made from your own blood. The PRP is then injected into a specific site on the body, where it acts locally to stimulate cellular rejuvenation and proliferation.

A 2013 study looked at 11 men suffering from androgenic alopecia, who had been on specific hair loss treatment drugs for at least six months without much improvement. Hair pull tests were performed three times by the same clinician prior to each session – a test to see how many hairs fall out when a collection of hair is pulled. About 50 or 60 hairs are grasped with the fingers close to the scalp.

Anaesthetic was applied to the bald areas of the head prior to treatment, and then the PRP was applied with multiple small injections. This treatment was repeated every two weeks for a total of four sessions. Each visit saw hair count noted and photographs taken, with all of the study participants evaluated after 12 weeks.

Results of the hair loss treatment study using PRP

Before the hair loss treatment, all the men had a positive hair pull test, with a mean number of 10 hairs removed per pull test. After the fourth session, the pull test was negative in 9 patients out of the 11 total patients, with an average number of three hairs.

A significant drop in the amount of hair lost over the treatment period was noted by the participants between the first and fourth injection. There was a moderate improvement in hair volume and coverage.

After four hair loss treatment sessions of PRP, the average number of follicular units was 93.09, compared with 71 at the start of the study. That is an average mean gain of 22.09 follicular units per cm2. Patient satisfaction was high.

Side-effects noted include minimal pain, redness, and pinpoint bleeding.

Why hair loss treatments matter

Hair loss is associated with psychological distress, low self-esteem and depression in both men and women. Hair loss treatment options are so limited, with testosterone-blocking drugs that have unpleasant side-effects, such as headaches and an increase in other body hair for some. Loss of libido has also been noted for some of these drugs.

PRP is popular in plastic surgery, orthopaedic surgery and cardiac surgery because it can help skin rejuvenate, encourages rapid healing, reduced infection rates, and less chance of keloid and other scarring. The growth factors involved seem to be the most important factor, as they activate the proliferative phase and transdifferentiation of hair and stem cells to get new follicular units producing hair.

The study concluded that PRP injection on the scalp as a hair loss treatment for androgenic alopecia is a simple, cost-effective and feasible treatment option for hair loss.
