PRP for Hair Loss

PRP is prepared by drawing a small amount of blood and centrifuging it to isolate plasma rich in platelets. Platelets release growth factors that influence tissue repair, blood vessel formation, and cellular signaling. When injected into the scalp, PRP stimulates hair follicles that are miniaturizing but not permanently destroyed.

The goal is not to create entirely new follicles, but to strengthen existing follicles, prolong the growth (anagen) phase of the hair cycle, and increase hair shaft thickness. Results depend on the presence of viable follicles. Completely bald areas where follicles are no longer active generally do not respond.

PRP is most effective in individuals with early to moderate hair thinning. Men and women with pattern hair loss who still have fine, miniaturized hairs in thinning areas are typical candidates. Younger patients and those who seek treatment early generally respond better than those with long-standing, advanced hair loss.

Patients with active scalp infections, certain platelet conditions, uncontrolled autoimmune disease, or significant blood disorders may not be ideal candidates for PRP treatment. It’s also important to have realistic expectations. PRP is designed to help slow hair loss progression and improve hair density, but it does not typically restore areas of advanced baldness.

The treatment is performed in an office setting. After blood is drawn and processed, PRP is injected into areas of thinning using small needles. The procedure typically takes 30 to 60 minutes and has minimal downtime. Mild swelling, scalp tenderness, or pinpoint bleeding can occur but usually resolve within a day or two.

PRP is most effective when performed as a structured series rather than a single treatment. We typically recommend an initial course of 3–4 sessions spaced approximately four weeks apart, followed by maintenance treatments every 3–6 months to help preserve and build upon your results. Some patients benefit from ongoing maintenance to sustain optimal improvement over time.

Hair restoration with PRP is a gradual process. Early changes, such as reduced shedding, may be noticed within the first few months, while visible improvements in thickness and density typically emerge around three to six months. The full effect often continues to develop over six to twelve months.

Clinical studies show that PRP can increase hair density and hair shaft diameter in patients with androgenetic alopecia. Individual responses vary, but many patients experience noticeable thickening and reduced shedding over time.

PRP is often combined with other therapies such as topical minoxidil, oral medications, low-level laser therapy, or hair transplantation. Combination therapy generally produces stronger and more sustained results than PRP alone.

PRP for hair loss is a biologically based therapy that aims to strengthen existing follicles and slow the progression of thinning. It is most effective when started early and used as part of a comprehensive treatment strategy. While PRP can improve hair quality and density, it is not a cure for baldness and does not replace surgical hair restoration in advanced cases. A careful evaluation is necessary to determine whether viable follicles are present and whether expectations align with likely outcomes.
