Age is an important factor to consider when evaluating the effectiveness of Platelet-Rich Plasma (PRP) therapy for hair restoration. While PRP is generally safe and effective for a wide range of adults, the patient’s age can influence both the response to treatment and the expected results. Hair loss patterns, follicle health, and regenerative capacity all vary with age, making this consideration essential for optimal outcomes. Younger adults, typically in their 20s and 30s, often respond well to PRP therapy. At this age, hair follicles are usually still active, even if they are thinning or in the early stages of miniaturization. PRP’s growth factors can effectively stimulate these follicles, improve blood circulation to the scalp, and encourage the follicles to re-enter the active growth phase. For younger patients, PRP is particularly effective in slowing the progression of hair loss, strengthening existing hair, and maintaining overall scalp health.
