Hair Transplant vs PRP: Which Comes First?

At a glance

What it is. PRP: Your own blood is drawn, spun to concentrate platelets and injected into the scalp. Hair transplant: Surgery that moves healthy hairs from one part of the scalp to thinning areas (AAD).

Is it permanent? PRP: No. AAD: "not a permanent solution"; maintenance treatments help keep results. Hair transplant: Transplanted hair is described by AAD as a permanent solution; native hair can keep thinning, so medicine may still be advised.

FDA status. PRP: Some PRP preparation systems are cleared for orthopedic uses; use for hair is off-label because no data were submitted to FDA for that use (ISHRS). Hair transplant: FDA-approved hair-loss drugs are separate: minoxidil and finasteride (AAD).

Evidence. PRP: ISHRS: multiple studies, some show benefit and others don't; protocols vary and aren't standardized. Hair transplant: AAD: results depend largely on the surgeon; candidates need donor hair and the ability to grow hair in the thinning area.

Typical session pattern. PRP: A common program is three monthly sessions, then booster sessions about every six months (ISHRS); AAD describes monthly for three months, then every three to six months. Hair transplant: A single surgery of about 4 to 8 hours; a larger one may need a few hours the next day (AAD).

When results show. PRP: ISHRS: visible growth can start at 1 to 2 months and take up to 6 months. Hair transplant: AAD: most patients see results at 6 to 9 months, some at 12; transplanted hair sheds at 2 to 8 weeks, which is normal.

Best candidates. PRP: ISHRS: thinning rather than complete baldness, and more recent loss. Hair transplant: AAD: enough healthy hair to transplant and ability to grow hair where it's thin; men in their 20s may be asked to wait and start medicine.

How sources describe its role. PRP: ISHRS: can be an effective adjunct for patients having surgery or using medication. Hair transplant: AAD: a permanent option; candidates need enough healthy donor hair.

So which should come first?

Step 1: find out what is causing the hair loss. AAD says effective treatment starts with finding the cause, and that a board-certified dermatologist may use a scalp exam, blood tests or a biopsy. Shedding from illness, stress or a deficiency, patchy loss or scalp symptoms need a different plan than pattern hair loss. See What Causes Hair Loss? and When to See a Doctor for Hair Loss.

Step 2: for pattern hair loss, ask about medicine. Minoxidil (topical, available without a prescription) and finasteride (for men) are the FDA-approved medications AAD lists for male pattern hair loss. The ISHRS PRP page, written from one physician's view, says PRP is best performed after other non-invasive treatments, including minoxidil and finasteride (an opinion piece by its author, not a guideline). See Minoxidil and Finasteride: How to Use Them Together.

Step 3: PRP is an optional add-on. AAD says PRP can be used alone or given before a transplant to improve results. ISHRS says PRP can be an effective adjunct for patients undergoing surgery, using medication or using photobiomodulation, but also that benefits aren't guaranteed, some patients see none and benefits fade without ongoing treatment.

Step 4: a transplant is for stable loss with enough donor hair. AAD says candidates need enough healthy hair to transplant and the ability to grow hair in the thinning area, and that a man in his 20s may be asked to wait and treat with medicine first because loss can continue. ISHRS says nothing produces long, thick, dense hair in the recipient area as well as surgical hair restoration.

Step 5: keep treating after surgery. AAD says hair loss and thinning can continue even after a transplant, so a dermatologist may recommend medicine to keep results.

Is PRP used with a transplant?

Sometimes. ISHRS describes three ways PRP may be used around transplant surgery: to help keep harvested follicles viable (for example, in the storage solution), to promote healing of the donor and recipient areas, and to stimulate dormant follicles. ISHRS also says:

reports of these benefits are usually single cases or small series and don't meet the definition of clinical trials;

some investigators suggest PRP shouldn't be used routinely to promote healing in transplants, though it might help patients with previous injury or scarring at a transplant site;

the FDA has not approved PRP for hair transplantation, and claims that it is "FDA approved" for this are incorrect.

So "PRP before or after a transplant" is a question for your surgeon about their protocol, not a required step.

Which situations point where? (general)

Early thinning, still has hair in the area: Diagnosis, medicine, and possibly PRP as an add-on.

Loss that is advancing or not yet stable, especially in your 20s: Medicine first; surgery later if appropriate (AAD).

Stable pattern loss, good donor hair, wants a permanent result: Transplant evaluation; medicine afterward to protect native hair.

Almost no donor hair or complete baldness in the area: PRP is not likely to help in a bald area (ISHRS); a transplant needs enough donor hair (AAD).

Hair loss from another cause (illness, stress, scalp disease, autoimmune): Treat the cause first; a transplant isn't a first step.

Questions to ask before you book

1. What is my diagnosis, and how do you know?

2. Am I on, or a candidate for, minoxidil or finasteride first? What would you expect from them?

3. If you recommend PRP, what system and protocol do you use, and how will we decide whether it's working?

4. If you recommend a transplant, how many grafts might I need, how much donor hair do I have, and what's the plan if my loss continues?

5. Who performs each step of the surgery, and how many transplants does the surgeon do?

6. What does the quote include, and is anything billed separately? (Ask for it in writing.)

7. What happens if I stop treatment?
