The verdict: thinning or bald
The deciding question is whether hair in the problem area is thinning or gone. PRP suits men whose hair is still present but getting finer and sparser, typically at early to middle Norwood stages or with diffuse thinning across the top. A hair transplant suits men with areas that are already bald, enough healthy donor hair at the back and sides, and a pattern of loss that has settled. Many men need both at different points: PRP to protect and thicken what they have, grafts to fill what is gone.
PRP and hair transplant side by side
| PRP | Hair transplant | |
|---|---|---|
| What it does | Thickens shrinking hairs that are still growing | Moves living follicles into bald or very thin areas |
| Stage it fits | Earlier stages and diffuse thinning | Established bald areas with good donor supply |
| Can it regrow fully bald skin? | No | Yes, within the limits of donor hair |
| Procedure | Blood draw, then scalp injections with numbing | Surgery, often four to eight hours, under local anesthesia |
| Recovery | Soreness for a day or two | Bandaging, home care; transplanted hair sheds first |
| Results timeline | Gradual, over months | Most see results at six to nine months, some at 12 |
| Permanence | Needs maintenance | Grafted hair is permanent; native hair keeps thinning without treatment |
| FDA status | Not FDA-approved for hair loss | Surgical procedure |
| FSA/HSA | Generally not eligible as cosmetic | Generally not eligible as cosmetic |
Reading your Norwood stage
The Norwood scale, first published in 1975 as a classification of male pattern baldness, describes seven stages, from a full hairline at stage 1 to a horseshoe of hair around the sides and back at stage 7. It was built to help select men for transplant surgery, and it remains the common language between patients and surgeons.
As a rough guide to where each treatment fits:
- Stages 2 and 3: early recession at the temples, sometimes thinning at the crown. Hair is mostly still present, so this is where PRP and medicine do the most. Our page on a receding hairline covers this stage.
- Stages 4 and 5: larger thinning areas at the front and crown, with a band of hair between them. A mix of thinning and bald zones, so this is often where men combine treatments.
- Stages 6 and 7: the front and crown have merged into a large bald area. Only grafts can add hair here, and the limit is how much donor hair is left.
Diffuse thinning that does not follow the Norwood pattern behaves differently. It is often a better fit for PRP than surgery, as explained on our PRP for diffuse hair thinning page.
How PRP works on miniaturizing hair
In male pattern loss, follicles shrink over years, making thinner, shorter hairs before they stop altogether. PRP concentrates growth factors from your own platelets and places them in thinning areas to support those shrinking follicles. A 2023 meta-analysis of 10 randomized trials found that PRP raised hair density, with a stronger effect in men, though hair thickness did not clearly change.
The American Academy of Dermatology describes PRP as able to lessen hair loss within a few months, not permanent, and usable on its own or before a transplant to improve results. It is not FDA-approved for hair loss. Our answer on how many PRP sessions men usually need covers typical schedules.
How a transplant works, and who qualifies
A transplant takes follicles from the back and sides of the scalp, which resist DHT, and places them where hair has been lost. The AAD’s hair transplant guide lists two requirements: enough healthy donor hair, and the ability to grow hair in the thinning area. The American Society of Plastic Surgeons adds that someone with very little remaining hair may not be advised to have surgery.
The AAD also sets expectations for recovery: transplanted hair falls out between two and eight weeks after surgery, the scalp may look thinner around the third month, and most men see results between six and nine months.
Why transplant patients keep treating afterward
Grafted follicles keep growing, but the native hair around them does not stop thinning. The AAD notes that medicine helps after a transplant because hair loss can continue. Without that, a man can end up with a dense transplanted hairline and a widening thin zone behind it. Finasteride and minoxidil are the most studied ways to protect native hair, compared in our PRP versus finasteride page. PRP is another option some men use after surgery, especially those who want to avoid a daily pill, though research on that specific use is limited.
Cost and how Ultimate Male fits in
Surgery is a larger single cost; PRP is smaller per session but ongoing. When you compare them, count the full picture: a transplant is often followed by years of medicine or maintenance treatment, and a large bald area may need more than one surgical session if donor hair allows. Both are generally considered cosmetic, and IRS Publication 502 specifically lists hair transplants among procedures you generally cannot count as medical expenses, so FSA or HSA funds usually do not apply.
Ultimate Male does not perform hair transplants. Its hair service is PRP, offered in San Gabriel and Downey, and the consultation includes an honest read of your stage. If your scalp has areas only grafts can fill, the provider tells you so and suggests you see a hair restoration surgeon, while PRP can still help protect the hair you have. Our guide to whether PRP suits you is a useful first read, and the full service is on the hair restoration page.
