PRP Therapy: The Science and Benefits Behind the Hair Growth

Platelet-Rich Plasma (PRP) therapy is a non surgical solution for individuals experiencing hair thinning or early stage hair loss. Also used in orthopaedics for its healing properties, PRP is now gaining widespread attention in dermatology and aesthetic medicine, particularly for its role in stimulating hair regrowth. 

The treatment harnesses the regenerative power of the body’s own plasma, which is known for its high concentration of growth factors that promote cell repair and regeneration.

The process begins with a simple blood draw from the patient, which is then placed in a centrifuge to separate its components. The platelet rich plasma is extracted and injected directly into areas of the scalp that show signs of thinning. These injections deliver a potent blend of growth factors, which work to increase blood supply to the hair follicles, stimulate follicular stem cells, and extend the growth phase of the hair cycle. The result leads to a healthier scalp environment that supports thicker, stronger hair.

In some cases, PRP may be beneficial for individuals with (androgenetic alopecia) the most common form of hair loss in both men and women, as well as those experiencing hair thinning due to stress or hormonal changes. Patients typically undergo a series of sessions spaced between 6 to 4 weeks apart, with maintenance treatments recommended every few months.

Now, this is personally my favourite part! One of the most appealing aspects of PRP is that it is a natural, autologous treatment, meaning it uses the patient’s own biological material, reducing the risk of allergic reactions or complications.

While results vary depending on the individual’s age, genetic predisposition, and overall health, many report noticeable improvements in hair texture, density, and reduced shedding after just a few sessions. Though PRP is not a cure for baldness, it serves as an effective way to preserve existing hair and promote regrowth in areas that still contain active hair follicles.
