Does PRP or PRF actually improve skin quality or hair growth?
⚠️ When to contact your provider after treatment
Some redness, swelling, or tenderness at injection sites is normal and usually resolves within a day or two. Contact your provider promptly if you develop increasing pain, warmth, pus, fever, or signs of an allergic reaction such as hives or difficulty breathing, as these could indicate infection or another complication.
Short answer
Yes, the research suggests both PRP and PRF can produce real but modest improvements in skin texture and hair density. Multiple systematic reviews find positive results, though studies are often small and preparation methods vary widely. PRF may have an edge over PRP in some comparisons, but both are considered promising and generally safe.
What the research shows for skin quality
Several systematic reviews have looked at PRP for aging skin and facial rejuvenation. One review covering 24 studies, including 8 randomized controlled trials, found that PRP injections produced at least a temporary, modest improvement in facial skin texture, fine lines, and appearance, though improvements were typically less than 50%. Patient satisfaction was generally high. [6] A broader review of 96 studies on platelet concentrates (PRP, PRF, and related products) confirmed positive outcomes for skin rejuvenation, acne scarring, and peri-orbital areas, and noted that the few studies directly comparing PRP to PRF tended to favor PRF. [2] A separate systematic review of injectable PRF specifically found moderate to significant improvements in skin texture, elasticity, and wrinkle reduction in four studies. [5]
What the research shows for hair growth
For hair loss, the evidence is also encouraging. A systematic review of PRP in aesthetic dermatology reported mean increases of 18 to 27.7 hairs per square centimeter in treated areas. [3] PRP works partly by releasing growth factors that extend the active hair-growth phase and improve follicle health. [4] PRF has also shown noticeable improvements in hair density and growth in studies on androgenetic alopecia (common pattern hair loss). [5] A review of microtrauma-based treatments confirmed that both microneedling and PRP can increase hair density in androgenetic alopecia and telogen effluvium (stress-related shedding), and that combination approaches may boost results further. [1]
Important caveats
While the overall direction of the evidence is positive, there are real limitations to keep in mind. Most studies are small, and there is no single agreed-upon way to prepare or inject PRP or PRF, which makes comparing results difficult. [6][2] Longer follow-up data is largely missing, so how long benefits last is not well established. [3] Experts consistently call for larger, well-designed randomized trials with standardized protocols before firm conclusions can be drawn. [5] These treatments are generally considered safe, but results can vary depending on the provider's technique and the individual patient.
What to ask your provider
Before booking a treatment, consider asking: How many sessions will I need, and how far apart? What preparation method and device does your clinic use? What realistic improvement can I expect, and how long might it last? Are there before-and-after photos from their own patients? Because protocols vary so much between clinics, the answers to these questions can meaningfully affect your outcome.
