Exosome therapy for hair: an honest look
A newer adjunct with a younger evidence base than PRP. You are entitled to know that before you pay for it.

Exosomes are signalling vesicles delivered into the scalp dermis, usually through microneedling or immediately after a transplant, intended to prompt follicles into a growth phase. It is an adjunct rather than a primary treatment, and its evidence base is younger and thinner than that for PRP. This clinic says so before you book it.
What an exosome is
Cells communicate partly by releasing small membrane-bound packets containing proteins and genetic material. Those packets are exosomes. Delivered into tissue, they carry signals that can influence how nearby cells behave. In hair, the intention is to signal dormant or miniaturising follicles towards the growth phase.
Why we are careful about it
Two reasons, and both are worth saying out loud. First, the published evidence for exosomes in hair loss is considerably younger and smaller than the evidence for PRP, and much of it is early-stage. Second, the products vary enormously in source, concentration and regulatory status, so results reported with one preparation do not transfer to another.
That does not make it a bad treatment. It makes it a treatment where you should be told what is known and what is not, before rather than after.
How it is used here
- •As an adjunct alongside surgery or alongside a medical protocol, not as a replacement for either
- •Two to three sessions, six to eight weeks apart
- •Assessed against baseline photographs at month four to six, with stopping treated as a legitimate outcome
- •Never offered to somebody whose hair loss has not been diagnosed
Aftercare is short
The delivery is usually through microneedling, so the skin barrier is briefly open. Nothing on the scalp for twenty-four hours, no sweating, no sun, and no chemical services for five days. Paracetamol rather than anti-inflammatories for seventy-two hours, for the same reason as PRP.
The question to ask
If any clinic offers exosome therapy, ask what it is expected to add over PRP or GFC in your specific case, and what the plan is if there is no measurable change at month six. A clear answer to both is a good sign. A brochure is not.
