For a lot of women with early thinning, PRP can help. A 2024 review of 21 trials with 628 women found that it improved hair density and thickness, and the side effects were mild.
It works best on the right kind of thinning, though. That is why we look at your scalp before we suggest it.
PRP stands for platelet-rich plasma. We take a small sample of your own blood and spin it, so the platelets gather together.
Platelets contain growth factors. Your body uses these to signal repair. We inject the PRP into the scalp, right where your hair is thinning.
In a thinning area, the follicles are usually there. They have shrunk, so each new hair comes in finer and shorter. The growth factors in PRP support blood flow to those follicles and help nudge them back toward a healthier growth phase.
PRP is one of three options on our female hair loss treatment page. Which one fits you depends on what is behind your thinning.
The research points to yes for many women, with a few limits worth knowing. Two terms come up a lot. Density is how many hairs grow in a patch of scalp, and thickness is how wide each hair is.
A 2024 systematic review in Skin Research and Technology pooled 21 randomized trials with 628 women. Hair density and hair thickness both went up with PRP. Fewer hairs came out in a gentle pull test, too.
Side effects in those trials were mild and short. Pain was about the same in the PRP groups and the comparison groups.
The same review found that results changed with the dose, the injection schedule and the patient’s ethnic background. Its authors call for plans built around each patient.
A 2023 review in the Journal of Dermatological Treatment looked only at female pattern hair loss. PRP raised the number of full, thick hairs compared with the control groups. Its numbers showed no clear change in hair thickness.
Those authors also asked for caution, because the studies were small. We think that is fair, and we say so at the consultation.
Female pattern hair loss is the genetic kind that shows up in families. It often looks like a part that gets wider, or thinning over the top of the head.
PRP is a good fit in the early to moderate stages of thinning. The follicles in the thin areas need to be alive and making hair, even if it is finer.
It also suits women who are fine with a blood draw and with needles in the scalp. You need to commit to a series of visits, plus maintenance later.
Thinning around menopause is part of the same conversation. Changing hormones can make hair grow finer, so we ask about your life stage at the first visit.
Some thinning has a different cause. PRP cannot fix that cause, so we look for it first.
Advanced loss. If few follicles are left in an area, PRP has less to work with.
Shedding after a baby. It often settles within a year on its own.
Thyroid problems or low iron. Your family doctor may need to test these first.
Stress, illness or surgery. Hair loss from these often stops after a while.
Treating the scalp while another cause goes untreated wastes your time and your money. If PRP is unlikely to help you, we will tell you.
Some women would prefer to skip the blood draw. Our hair loss treatments include two other options that need no blood at all.
Some women do well with one treatment. Others get more from two treatments used together, and we explain our reasoning either way.
Most patients need a series of 3 to 6 treatments. They are spaced 4 to 6 weeks apart.
After the series, maintenance visits every 6 to 12 months help protect your progress. Our PRP page recommends them most for genetic thinning.
Each visit starts with a short check of your scalp and goals. Next comes a small blood draw, which we spin to separate the PRP.
Then we inject the PRP into the thinning areas, and numbing is available. The scalp can feel tender for a short time, so you leave with aftercare advice.
Hair grows slowly, so we talk about change in months. Results vary from person to person, and we make no guarantees. Our PRP hair restoration page explains each step of a visit in more detail.
Kontour is led by Belita Savage, a nurse practitioner. Your first visit is a scalp assessment that follows her clinical protocols, and you can ask to book with Belita herself.
At that visit, we ask when you first noticed changes and how fast they came on. We look closely at your part line, temples and crown.
Our clinic is at 1599 Adelaide Street North in London. The first visit leaves time for your questions.
We also go over your health history. That includes hormones, thyroid, iron, medications, pregnancy and menopause.
Then we explain what we see in plain words. You leave with a recommendation, the reason for it, and a timeline. There is no pressure to book treatment that same day.
If your hair has been thinning and you want to know why, book a consultation with our team in London, Ontario. We will look at your scalp, answer your questions and tell you if PRP is a good match for you.
