PRP for Hair Loss: What 14 Months of Photos Actually Showed

I ran this one on myself as an experiment and kept records, because the alternative was trusting a before-and-after wall in a lobby. Fourteen months: same bathroom lamp, same part, one photo every two weeks. Four loading sessions of PRP for hair loss, then maintenance, then finally enough data to say something better than "I think it's working?"

The ledger: four sessions at $600 each at a med spa outside Atlanta, plus $180 of bloodwork my provider refused to skip. That $180 is the line item I'd defend hardest, and I'll come back to why.

What is PRP for hair loss, and how is PRF different?

PRP is platelet-rich plasma. They draw two vials of your blood, spin them in a centrifuge, and separate the straw-colored plasma layer carrying a concentrated dose of your own platelets. Platelets are packed with growth factors; the premise is that delivering them into a scalp of shrinking follicles nudges those follicles back toward thicker hair.

Every clinic leads with "it's your own blood," which is mostly true rather than entirely true. Standard PRP is drawn into a tube containing an anticoagulant — sodium citrate or ACD-A — so the sample doesn't clot before the centrifuge can separate it, and many protocols then add calcium chloride to reactivate the platelets on the way back in. Your platelets, your plasma, plus a little pharmacy chemistry doing the mechanical work. Not a scandal, but not "nothing synthetic" either.

PRF is platelet-rich fibrin: same idea, gentler spin, genuinely no anticoagulant. That absence is the real difference, not the marketing on top of it. You get a thicker preparation that releases growth factors over days rather than hours, sold as the premium tier at $100 to $200 more per session. My read, after a loading series of PRP and maintenance with PRF at $700 a pop: the head-to-head evidence is too thin to justify that gap. Same price, take PRF. Real premium, decline.

Does PRP for hair loss actually work, or is it expensive theater?

It works on a specific person: early-to-moderate androgenetic thinning, follicles miniaturizing but not gone. A widening part, a crown that photographs badly. If you can still see fine, wispy, short hairs in the thin areas, there's something alive down there to stimulate.

It does not work on shiny scalp. If an area has been slick and bare for years the follicle is gone, and no volume of your own plasma resurrects it. Same for scarring alopecias, where inflammation has already swapped follicles for fibrous tissue. Injecting growth factors into scar tissue is a $600 donation to a small business.

Be clear-eyed about the evidence, too. The published research is mostly small studies with wildly inconsistent protocols — different spin speeds, platelet concentrations, injection depths — which is exactly why results swing so hard from clinic to clinic. And PRP is not FDA-approved as a treatment for hair loss; the centrifuge systems were cleared as devices for preparing your own blood, which is a different sentence wearing a similar coat. That doesn't make PRP junk — it makes it off-label, with promising and messy evidence, and you deserve to know that before the needle comes out.

My own numbers: shedding dropped noticeably by month three, and at month four the part stopped photographing like a runway. Density improved — modestly, visibly, not dramatically. If you're expecting the hair you had at 24, keep your money.

Who should not get PRP for hair loss?

This is an injectable procedure, and injectables come with a list. Mine got checked at intake. If yours doesn't, you're doing quality control yourself.

• Active scalp infection. Folliculitis, an open flare, anything crusting or weeping. Dozens of needle passes through infected skin is how a local problem becomes a bigger one. Treat it, then rebook.
• Platelet or bleeding disorders. Thrombocytopenia, platelet dysfunction, clotting disorders. The treatment is built entirely on your platelets doing a job; if yours aren't in working order, the premise falls apart and the bruising risk climbs.
• Anticoagulant or antiplatelet therapy. Warfarin, the newer oral anticoagulants, daily antiplatelet drugs. That's a conversation with the physician who prescribed them, not with a consultant who wants to know if you're free Thursday.
• Active malignancy. You would be injecting concentrated growth factors. Careful providers defer to your oncology team; anyone who waves this off is not someone I'd let near me with a needle.
• Pregnancy and breastfeeding. Not studied, routinely declined.

What happens at a PRP appointment, and does it hurt?

Ninety minutes door to door, and about eleven of them are the part you're nervous about. Blood draw first. The vials go into a centrifuge on the counter; watch that happen, with your name on the tubes. While it spins, numbing cream sits on your scalp for 20 to 30 minutes. Then the injections: dozens of small ones, half an inch apart, across the thinning zones. Stinging pressure with the occasional sharp one that made me say a word I won't print, hairline worse than crown, the whole thing over faster than a dental filling.

You walk out with a damp, tender head and no bandage. Nobody can tell. The rougher stretch is the next 24 hours, when my scalp felt sunburned and touching my head was a bad idea. Aftercare is simple: no washing that day, no hard exercise for 24 hours, no heat tools or harsh chemical services for a couple of days, and no anti-inflammatory painkillers around the appointment. Don't book PRP the same week as color or a smoothing service — the keratin and smoothing comparison explains why that week is already chemically busy — and use a salon that will talk to your provider.

Shedding may briefly increase in weeks two through six, which is normal and terrifying. Real change shows up between months three and six, and in photographs before the mirror. Take baseline photos: same light, same part, same angle. It's the only reason I have anything useful to tell you.

How much does PRP cost per year, not per session?

Per-session pricing runs $400 to $1,200, most competent providers between $600 and $900 — nearly meaningless alone, because PRP is not a one-time purchase. The loading protocol is three to four sessions four to six weeks apart, so $1,800 to $3,600 in your first three months, then maintenance every three to six months, indefinitely, at $1,200 to $2,800 a year. Mine has settled at about $1,400.

Packages discount the loading series 10 to 20 percent and I took one, but read the terms like a lease: plenty are non-refundable and expire at twelve months, the arithmetic that makes med spa memberships a quiet trap for people who don't show up. Geography moves it too. Atlanta and Dallas price like value markets, while Los Angeles and Miami run twenty to thirty percent higher for the identical protocol, same tubes, same centrifuge.

What happens if you stop getting PRP?

You lose it. Not overnight, but over roughly six to twelve months the gains fade and you drift back toward your untreated trajectory.

The reason is structural: PRP doesn't touch the cause. Pattern hair loss is driven by hormonal sensitivity at the follicle, and plasma injections do nothing about that. You're stimulating follicles that are still being told to shrink, so when the stimulation stops, the shrinking wins on schedule. Treat it as a subscription rather than a cure, and budget for it or don't start.

How does PRP stack with minoxidil and prescription options?

PRP as a solo act is the most expensive and least effective way to do this. Every provider I'd trust treats it as an add-on to a foundation, not the foundation.

• Topical minoxidil is the cheap, boring, over-the-counter workhorse at $15 to $40 a month. If you won't use it daily, you almost certainly won't maintain PRP either. Same goes for the unglamorous scalp treatments that keep flaking and inflammation down.
• Prescription oral therapies are the only category that addresses the hormonal driver, and they need a real physician conversation about risk and candidacy. I'm not going to discuss dosing, and neither should a med spa consultant. The American Academy of Dermatology publishes patient guidance worth reading first.
• Microneedling pairs well with PRP and some clinics combine them in one visit. It runs $250 to $500 a session, around $300 typical, in a course of three or four spaced four to six weeks apart; if someone pitches a radiofrequency version instead, read the Morpheus8 comparison and the microneedling risks breakdown first.

Now, the $180. My bloodwork came back with low ferritin — iron stores in the basement. Iron, thyroid and vitamin D problems all drive shedding, and correcting one is dramatically cheaper than injecting plasma into a problem that was never follicular. A provider who won't order labs before taking $2,400 from you has skipped the step that might have saved you the $2,400.

What are the red flags when choosing a PRP provider?

Walk out if you hear or see any of these.

• A promise of regrowth on a fully bald, shiny area. Not physiologically possible, and offering it tells you how the rest of the conversation goes.
• "Guaranteed results," or before-and-afters with mismatched lighting, wet-versus-dry hair, or a different part. Ask for same-lighting pairs from patients with your pattern.
• No exam, no scalp magnification, no diagnosis, no labs. A consult that goes straight to pricing is a sales meeting with a robe on.
• Pressure to prepay six or eight sessions. Three or four is the loading series. More upfront is cash flow, not medicine.
• Your blood leaving the room. Draw, spin and inject should happen in front of you.

Cross-check reviews that mention hair, the way you'd read any beauty business review — five stars for "friendly staff" tells you nothing about density at month six. And if what you want is coverage next month rather than density next year, that's an extensions question.

The three things that would make me spend this money again

I did spend it again. I'm on maintenance, renewed with my eyes open, because of three conditions — and if any one stopped being true I'd stop.

One: the labs came back with nothing left to fix. The ferritin got corrected months before a needle touched my scalp, so the improvement in my photos isn't just iron doing its job while a med spa takes the credit. Run the workup in the wrong order and you can never separate those two stories.

Two: there are still fine hairs in the thin zones under magnification. That's my go/no-go, checked at every visit. The day someone puts the dermatoscope down and tells me the part line has gone smooth, PRP becomes a donation.

Three: $1,400 a year is absorbable, forever. Not absorbable-if-I-skip-a-trip. Forever, because stopping hands the gains back inside a year and I'd have bought a very expensive photo album. The moment it competes with something I actually need, PRP comes off the budget — a call I'd rather make at a kitchen table than in a treatment chair.

Everything else is negotiable: clinic, tube, PRP or PRF, quarterly or twice a year, which med spa gets the business. Those three aren't. Tick all three and this is a defensible way to spend money. Tick two and wait — nothing gets worse in the eight weeks it takes to run labs and take baseline photos. You'll want them either way. They cost nothing and they don't flatter anybody.
