Platelet-Rich Plasma — Regenerative Hair Treatment
PRP (Platelet-Rich Plasma) therapy is a regenerative treatment that uses concentrated growth factors from your own blood to stimulate hair follicles. A blood sample is drawn, processed in a centrifuge to concentrate platelets, and the resulting plasma is injected into areas of thinning hair.
Platelets contain growth factors including PDGF, TGF-β, VEGF, and IGF-1, which promote cell proliferation, tissue repair, and new blood vessel formation. When injected into the scalp, these factors can activate dormant follicles and improve hair density.
A small blood sample (30-60ml) is drawn from your arm, similar to a routine blood test.
The blood is placed in a centrifuge for 10-15 minutes to separate and concentrate the platelet-rich plasma from other blood components.
The concentrated PRP (containing 3-5x normal platelet concentration) is extracted and prepared for injection.
Local anesthetic or numbing cream is applied to the treatment area to minimize discomfort.
The PRP is injected into the scalp at the level of the hair follicles using a fine needle, targeting areas of thinning. The procedure takes about 30-60 minutes total.
PRP therapy uses your own blood. A sample is drawn, centrifuged to concentrate the platelets, and the platelet-rich plasma is injected into the scalp. Growth factors in the concentrated platelets stimulate dormant hair follicles, increase blood supply, and promote new hair growth.
Most protocols recommend 3-6 initial sessions spaced 4-6 weeks apart, followed by maintenance sessions every 3-6 months. Results vary, but many patients see improvement after 2-3 sessions. Long-term maintenance is typically needed to sustain results.
PRP sessions typically cost $500-$2,000 each in the US, depending on the provider and preparation method. A full initial course (3-6 sessions) costs $1,500-$12,000. Insurance typically does not cover PRP for hair loss as it is considered cosmetic.
Most patients describe PRP as mildly uncomfortable rather than painful. Local anesthetic or numbing cream is applied before the injections. The blood draw is similar to a standard lab test. Some scalp tenderness may persist for 1-2 days after treatment.
