How PRP works on the scalp

In androgenetic hair loss — the pattern thinning that affects both men and women — follicles do not disappear all at once. They miniaturize. Each growth cycle produces a slightly finer, shorter, less pigmented hair until the follicle eventually stops producing anything visible.

Platelet-rich plasma targets that window. We draw a small blood sample, concentrate the platelet layer, and inject it into the scalp at the level of the follicles. The growth factors those platelets release increase blood supply to the follicle, extend the active growth phase of the hair cycle, and can push miniaturized follicles back toward producing thicker hair.

The critical point is timing. PRP can revive a weakened follicle. It cannot recreate one that is gone. Areas that have been completely bald for years will not respond, which is why we assess your scalp honestly and will tell you if we do not think you are a good candidate.

Who it works best for

• Men and women with early to moderate pattern hair loss
• Diffuse thinning where hair is still present but noticeably finer
• Widening of the part line in women
• Recession at the temples and crown in men, before full baldness
• Postpartum hair loss and thinning after significant stress or illness
• Patients who want to strengthen results from finasteride or minoxidil
• Patients hoping to improve density before or after a hair transplant

Finding out why you are losing hair first

Not all hair loss is genetic, and treating the wrong cause wastes time and money. Thyroid disease, iron deficiency, low vitamin D, certain autoimmune conditions, rapid weight loss and some medications all cause shedding — and several of those are correctable.

Because we are also a primary care practice, we can order and interpret the relevant bloodwork as part of your evaluation rather than sending you elsewhere. If a treatable medical cause is found, addressing it may resolve the problem on its own or substantially improve how well PRP works.

The appointment

A blood sample is drawn and spun in a centrifuge for about ten to fifteen minutes. Meanwhile the scalp is cleansed and numbed. The concentrated plasma is then injected across the thinning areas in a grid pattern using a very fine needle. The full appointment takes roughly forty-five to sixty minutes.

You can return to normal activity immediately. Scalp tenderness for a day or two is common. Do not wash your hair for the rest of the day, and avoid strenuous exercise, swimming and hair colouring for 48 hours.

Protocol and expectations

The standard protocol is three to four sessions spaced four to six weeks apart, followed by maintenance every four to six months. Hair growth is slow biology: most patients notice reduced shedding first, at around two months, with visible density changes from four to six months onward.

PRP is a maintenance treatment, not a cure. It does not switch off the genetic and hormonal drivers of pattern hair loss, so stopping maintenance means gradually losing ground again. We are direct about this before you start.
