PRP for hair loss is a non-surgical treatment that uses your own blood to support hair restoration. PRP stands for platelet-rich plasma. During the procedure, a small amount of blood is taken, processed in a centrifuge to concentrate the platelets, and then injected into the scalp. Dermatology and clinic guidance describe PRP as a treatment that may help reduce hair shedding and support regrowth in some patients with hair loss.

So, how does PRP work for hair loss? Platelets contain growth factors and other bioactive components that are thought to support the hair follicle environment. Recent reviews suggest that PRP can improve hair density and may reduce hair loss, especially in people with androgenetic alopecia, also known as pattern hair loss. At the same time, researchers note that results vary because PRP protocols are not fully standardised yet, and more high-quality studies are still needed.

PRP is usually considered for people with thinning hair or early to moderate stages of pattern hair loss rather than every type of hair problem. This is important because not all hair loss has the same cause. The American Academy of Dermatology notes that different forms of hair loss require different treatment plans, which is why a professional consultation is the first step before starting PRP hair treatment.

Patients also often ask how many sessions they may need. Dermatology guidance commonly describes PRP as a course rather than a one-time treatment. A typical plan may involve monthly sessions for the first three months, followed by maintenance sessions every three to six months. PRP is also not considered a permanent solution, so ongoing maintenance may be recommended depending on the patient’s goals and response.

In terms of safety, PRP is attractive to many patients because it is an autologous treatment, meaning it is prepared from the patient’s own blood. Recent evidence reviews describe PRP as generally safe and well tolerated, with most reported side effects being mild and temporary, such as brief pain, redness, swelling, or bruising around the injection sites.

Overall, PRP for hair loss may be a good option for people who want a natural, non-surgical approach to hair restoration. It may be especially suitable for patients with pattern hair loss who are looking to improve hair density and reduce shedding as part of a personalised treatment plan. The best way to know whether hair PRP treatment is right for you is to have your scalp and hair loss concerns professionally assessed first.
