Yes, PRP (Platelet Rich Plasma) is effective for treating hair loss. A 2015 placebo-controlled trial showed that PRP has positive therapeutic effects on androgenic alopecia without major complications or side effects. PRP treatment encourages hair growth by supporting cellular maturation and proliferation, but it works best on those with hormone-related baldness–also known as male or female pattern hair loss.
Studies also indicate that PRP for hair loss is most effective when combined with oral, low-dose minoxidil tablets–a vasodilator that increases blood flow to hair follicles.
Who is a candidate for PRP hair loss therapy?
Ideal candidates for hair regrowth treatment with PRP injections are patients who have begun to experience mild to moderate male or female pattern hair loss, or androgenic alopecia, within the last few years. Here in our Dallas practice, we have found that the sooner our patients seek treatment after hair loss, the better the results. In women, hormone-related hair loss is usually characterized by thinning hair at the top of the scalp that resembles a wide part. In men, this type of alopecia begins at the hairline and gradually recedes to form an “M” shape.
How does PRP hair loss treatment work?
Plasma is rich in growth factors that signal cells to function properly. When injected under the scalp, PRP augments the body’s natural repair system, promoting the growth and differentiation of healthy tissue and blood cells. Recent studies have shown that PRP injections in patients with hormone-related baldness have seen improvements in hair count, thickness, and the follicular growth phase.
How is the procedure performed?
A small blood sample is taken from the patient and placed in a centrifuge to separate the platelet-rich plasma. Next, the skin is numbed with a topical cream before the PRP is injected with micro-needles under the scalp. The entire treatment lasts 45 minutes to an hour. Temporary swelling and tenderness are common side effects, but patients can immediately resume normal activities.
How long for hair regrowth after PRP?
Most patients will start to notice improvements after two or three months. Less hair shedding is the first sign as the follicle cells are restored and primed for regrowth. To realize the full benefit of this cutting-edge hair loss treatment, patients will be prescribed oral minoxidil and require multiple sessions. It generally takes six months from the initial PRP hair treatment to see measurable results. Follow-up PRP treatments may be recommended twice a year to maintain optimal results.
