How Many PRP Sessions Does Hair Need, and How Far Apart?
The usual starting course, the gap between sessions, when to judge whether PRP is working, and what maintenance means in practice.
Growth factor concentrate (GFC) is made from a small sample of your own blood, taken one processing step further than PRP. That step changes what is injected; it has not been shown to change the result. At our Rohini clinic in North-West Delhi, a GFC course starts only once the cause of your thinning is known, is measured against baseline photographs, and stops if nothing changes.

How it is made
Platelets carry growth factors, signalling proteins the body uses for repair. GFC aims to deliver those proteins, without the platelets themselves, to follicles that are weakening but still present.
With PRP the platelets are injected and release their growth factors gradually in the scalp; with GFC that release happens in the tube. The case made for this (less cell debris, a more predictable release) rests on the method, not on hair-growth results. Our page on hair PRP and GFC treatment in Rohini sets the two side by side.
Both are made from your own blood, so a reaction to the material itself is not expected. Neither creates new follicles.
The evidence
GFC is often sold as the newer, stronger form of PRP. The research does not support that description yet.
Some clinics quote how many times more growth factor a GFC tube holds. That number describes the tube, not your scalp. The studies behind GFC are fewer, mostly recent and often from a single centre, and few compare it directly with well-prepared PRP in the same patients. PRP’s own trials are mostly small and short. Our article on PRP, GFC and exosomes compared walks through the research.
Side by side
Three scalp injection treatments that are often offered as alternatives. They differ in what goes into the syringe, where it comes from and how much research stands behind it, not in a proven difference in hair.
None of the three creates new follicles, and none cures pattern hair loss. More on each in hair PRP treatment in Rohini and hair mesotherapy in Rohini.

Suitability
GFC can only support follicles that are still alive, so the scalp examination settles most of this before any blood is drawn.
Unlikely to help: a smooth, bald scalp; shedding from untreated iron, thyroid or hormonal problems; recent diffuse shedding that may settle on its own (see telogen effluvium compared with pattern hair loss); or established baldness, where surgery is the real question.
Postponed or not offered: scalp infection or inflammation, a bleeding, clotting or platelet disorder, unreviewed blood thinners, some cancers and active chemotherapy, poorly controlled illness, pregnancy or breastfeeding, and significant anaemia. If the cause is unclear, start with hair fall treatment at the Rohini clinic.
May be considered for:
Step by step
Nothing is injected at the first visit. The aim is to find out whether GFC has anything to work on.

Step 01
Your history, medicines and a magnified look at the scalp, with blood tests if your history points to iron, thyroid or other causes. Anything treatable is dealt with first.

Step 02
Fixed angles and lighting. The plan names the preparation, the number of sessions, the review date and the cost of the whole course.

Step 03
Blood drawn and prepared, scalp cooled or numbed, concentrate injected at follicle depth in under an hour. At around three to six months the photographs are compared; no change means the course stops.
After a session
A general picture rather than a promise. Results vary, and some people do not respond at all.
Eat and drink as usual, since blood is taken. Mention aspirin, anti-inflammatory painkillers or blood thinners well before the day. Opening hours and directions to the Rohini clinic are on the clinic page.
GFC does not switch off pattern hair loss. If it helps, the benefit lasts only while maintenance continues, usually alongside medication: minoxidil, and finasteride in men, have a deeper evidence base, though neither is a cure (see minoxidil and finasteride in India). Once sessions stop, thinning generally resumes from wherever it had reached.
Recovering in Delhi
General practicalities for the day or two after a session. Where your written aftercare sheet says something different, follow the sheet.
Heavy sweating is one of the things to avoid for a short time. On a hot day, plan a cool, quiet rest of the day, and leave the gym or outdoor sport until your sheet allows.
Winter smog and roadside dust do not change the treatment, but a tender scalp should be kept clean. Wash gently when your sheet allows, and avoid scratching the injection sites.
A helmet can press on a tender scalp for a day or so. A clean liner helps, and if you ride every day, say so at the session.
Sessions spaced some weeks apart make the review a fair test. Plan the dates around festivals, weddings and travel so the gaps hold.
Before you pay
They apply wherever you have GFC, including here. Clear answers tell you more than any claim about which preparation is newest.
One preparation at a time. Mix GFC, PRP or other injections in one course and nobody can tell which did anything. One preparation, judged on standardised photographs, tells you more.
Cost guidance
We do not publish a single-session price, because it says little about the course you would need. Yours is quoted in writing after the assessment, with the sessions, the review point and maintenance shown separately.
Be wary of a large prepaid package sold before an examination; you want to be able to stop after review. How a PRP or GFC course is priced, and what a written estimate should include, is set out in PRP hair treatment cost in Rohini.
Instalment options through third-party lenders may be available; ask at the consultation, and read cost and EMI options before signing anything.
