Platelet-rich plasma – known as PRP – is a revolutionary treatment for hair loss or thinning in men. The treatment stimulates new hair growth using concentrated blood growth factors (in your own blood), which activate stems cells. The PRP in the skin then stimulates underdeveloped or under-active hair follicles, triggering their growth.
While this treatment isn’t appropriate for all men, it can make a huge difference in head hair for some men.
But does PRP for hair loss in men actually work?
Yes, but results definitely vary depending on the state of the scalp to start with, and what the cause of the hair loss is. Not every man will get a full head of hair after treatment, so expectations must be managed.
One study (Swapna et al 2014) concluded that, “PRP injection for androgenic alopecia is a simple, cost-effective and feasible treatment option for hair loss and can be regarded as a valuable adjuvant treatment modality for androgenic alopecia. … Considering its excellent safety profile and relatively low cost, PRP hair treatment is a promising treatment option for patients with thinning hair.”
The researchers took PRP to task on male hair loss after other treatments had failed to shift the follicles. Over the course of the four-injection study, hair count increased from an average of 71 hair follicular units to 93 hair follicular units – that was a total average mean gain of 22.09 follicular units per cm2. In real terms, that means hair per centimetre square of scalp increased by about 22 hairs.
Hair pull tests done before and after the study found that a mean of 10 hairs came out of each man’s head prior to treatment. After the PRP treatments were complete, the pull tests were negative – as in, no hairs came out at all – in nine out of the 11 men in this small study.
Patient satisfaction was high, an average of seven out of 10.
PRP for hair loss in men – what happens in a session
- The doctor takes blood from your arm – between 10 and 30ml.
- The blood spins in a special centrifuge designed for this explicit purpose, in ENRICH’s case, a state-of-the-art Angel Plasma device (it’s the best because it gets more PRP out than other machines). The centrifuge separates out the red and white blood cells from the plasma and platelets. The plasma and platelets – platelet-rich plasma – is what PRP is. This takes up to 10 minutes.
- The PRP is then injected using a special multi-pronged injector into your scalp, after anaesthetic.
- The process is complete for one session.
