Does PRP Work for Hair Loss?
Yes, for the most common type of hair loss, PRP has real evidence behind it. PRP, or platelet-rich plasma, uses growth factors from your own blood to stimulate hair follicles, and recent research, including a large 2025 review, found it increases hair density and thickness in pattern hair loss. It is not a cure or a guarantee. It works best as a series of treatments with maintenance, and often alongside other therapies.
In my more than 20 years in medicine, patients ask me one thing about PRP more than anything else: does it actually work, or is it hype? Here is the honest answer.
Here is how it works. We draw a small amount of your own blood, concentrate the platelets and the growth factors they carry, and inject that concentrate into the scalp to wake up and support the hair follicles. Because it comes from your own body, there is no foreign substance involved.
The research backs it up. A 2025 systematic review and meta-analysis pooling dozens of randomized trials found that PRP increased hair density and reduced further loss compared with placebo, with good patient satisfaction. The strongest evidence is for androgenetic alopecia, the pattern hair loss that affects both men and women, and results tend to improve when PRP is combined with microneedling or a topical like minoxidil.
| What the evidence supports | What to keep in mind |
|---|---|
| Increased hair density and thickness in pattern hair loss | It is not a cure, and results are not guaranteed |
| Uses your own blood, so no foreign substance | Best results build over a series of sessions and months |
| Better outcomes when combined with microneedling or minoxidil | Maintenance treatments keep the results going |
In my practice, here is what I see. PRP works best when it is started earlier, before too many follicles are lost, done as a proper series rather than a one-off, and paired with the right supporting treatments. Think of it as regenerative support that strengthens what you still have, not a way to grow hair where the follicles are already gone.
I will be straight about who it does not fit. If an area has gone completely bald, PRP cannot bring back follicles that are no longer there, and individual response does vary. That is exactly why an honest assessment comes first.
If thinning hair is on your mind, the next step is a consult where we look at your scalp and your goals and tell you honestly whether PRP is likely to help you.
