Who this guide is for
This guide is for men who have decided to try platelet-rich plasma (PRP) for thinning hair, or are close to deciding, and want to know exactly what happens in the room. If you are still weighing PRP against other options, start with the hair loss treatment roadmap, which shows where PRP fits by stage.
PRP works on follicles that are weakened but still present, so it suits thinning areas better than smooth bald skin. It is not FDA-approved for hair loss, and the research is mixed to promising; our answer on whether PRP for hair is FDA-approved explains what that status means.
PRP is not for everyone. It is usually postponed or ruled out for men with a bleeding or platelet disorder, a blood cancer under treatment, an active scalp infection or rash in the treatment area, or a fever on the day. Men on blood thinners need a review first rather than an automatic no. And because PRP does not block the hormone that drives pattern loss, it tends to make most sense as one part of a plan, often alongside minoxidil or finasteride, rather than the whole plan.
Before the visit: a short prep checklist
Most of the preparation is about making the blood draw easy and the scalp clean.
- Eat a normal meal and drink water in the hours before. A full stomach and good hydration make a blood draw smoother and reduce the chance of feeling faint.
- Wash your hair the morning of the visit and skip gels, sprays and oils.
- List your medicines, especially aspirin, anti-inflammatory pain relievers, fish oil and blood thinners, and tell the clinic when you book. Do not stop a medicine your doctor manages without talking to them.
- Mention any bleeding or platelet problem, active scalp infection, recent illness or a history of fainting with needles.
- Bring or plan for photos. The provider takes standard photos at the start; if you have your own baseline set, bring it.
- Wear a button-up or loose shirt so nothing has to be pulled over your head afterward.
The visit, step by step
Here is the usual order of a PRP hair session.
- Check-in and review. The provider confirms your history, medicines and goals, looks at the thinning pattern and takes photos in consistent light.
- Blood draw. A small amount of blood is drawn from your arm, much like a routine lab test.
- Centrifuge spin. The tube goes into a centrifuge, which spins it so the red cells separate from the plasma. As OrthoInfo explains, spinning concentrates the platelets so the plasma carries more of them than normal blood. While it spins, you wait in the room.
- Scalp numbing. A numbing solution is applied to the areas to be treated, and the provider gives it time to work.
- Injections across the thinning zones. The plasma is drawn into syringes and injected just under the skin with very fine needles. A 2019 review of PRP for pattern hair loss describes spacing injections across the thinning areas, typically the hairline, the part, the top and the crown. Your provider works section by section, parting the hair as they go.
- Wrap-up. Any pinpoint bleeding is pressed gently, you get aftercare instructions, and the next session is booked.
The American Academy of Dermatology says the plasma injection itself takes about 10 minutes. With check-in, photos, the draw, the spin and numbing time added, Ultimate Male describes its PRP visits as taking under an hour.
| Stage of the visit | What you do | What you feel |
|---|---|---|
| Review and photos | Answer questions, sit still for pictures | Nothing |
| Blood draw | Roll up a sleeve | A quick pinch |
| Centrifuge | Relax while the sample spins | Nothing |
| Numbing | Wait for it to take effect | Coolness or mild tingling |
| Injections | Keep your head still | Pressure and small pricks; most men find it tolerable |
| Wrap-up | Book the next session | Mild tightness or tenderness |
If pain is your main worry, read does PRP for hair hurt before the visit and ask about the numbing approach when you book.
How many sessions a first course includes
A single PRP session is not a test of whether PRP works. Results build over a course.
Ultimate Male’s hair restoration page says most men start with three to four sessions spaced about a month apart, followed by maintenance every 12 to 18 months. Your provider may adjust that based on your stage, your response and whether you are also using a medicine such as minoxidil or finasteride.
Outside guidance follows a similar shape but is not uniform. The AAD describes monthly sessions for the first three months, then one every three to six months. The 2019 review notes that the ideal number and spacing of sessions has not been established; several of the trials it summarizes used three sessions a month apart, and the authors propose continuing sessions every few months through the first year. The AAD adds that PRP is not permanent, so maintenance helps keep whatever you gain.
| Point in the course | What usually happens |
|---|---|
| Session 1 | Baseline photos, first injections |
| Sessions 2 to 4, about monthly | Repeat injections; little visible change yet is normal |
| Around 4 to 6 months | Visible improvement in thickness, if you respond |
| Up to 12 months | Improvement can keep building |
| After the first course | Maintenance spacing set by your response |
The question of how many sessions you personally need is covered in more depth in how many PRP sessions for hair.
After the session: what is normal and when to call
Expect mild redness, tenderness, a tight feeling or slight swelling of the scalp for a day or two, and possibly a dull headache. Tiny scabs at injection points are common. The PRP hair aftercare guide covers washing, exercise, hair dye and pain relief for the first 72 hours.
What to watch for: swelling that spreads toward the forehead or eyes and keeps increasing after the second day, warmth and throbbing at one spot, pus, or a fever.
When to call the clinic: any of the signs above; bleeding that does not stop with gentle pressure; a bruise that keeps growing; or numbness that lasts beyond the day of treatment.
When to call 911: trouble breathing, swelling of the lips, tongue or throat, fainting that does not resolve when you lie down, or chest pain. These are rare after PRP, but they need emergency care, not a callback.
How Ultimate Male runs PRP hair sessions
At Ultimate Male, PRP for hair is part of the hair restoration service at our San Gabriel and Downey clinics. The first visit includes an evaluation of your pattern, history and medicines, and labs if your shedding suggests another cause. A consultation is an evaluation, so if PRP is unlikely to help, for example because an area is fully bald, you will be told that before any course is booked.
Ultimate Male is direct-pay and does not bill insurance. You get a quote for the course before you commit, with bundle pricing available on multi-session plans and financing through CareCredit, Prosper Healthcare Lending or Afterpay. Under IRS Publication 502, procedures aimed mainly at improving appearance are generally not a deductible medical expense, so PRP for hair is usually not FSA or HSA eligible. See PRP hair restoration cost for what drives the price.
To book, call 626-319-5261 or schedule a PRP hair consultation.
