What it is
A group of injections given into the scalp to support a hair-loss plan that is already under way. PRP uses the patient's own blood, drawn and spun on the day so that the platelet-rich portion can be injected back into the thinning area; mesotherapy cocktails and polynucleotides are given by the same route. They are adjuncts — started after the cause of the shedding has been established and alongside the medical treatment for it, not instead of it.

- Scalp mesotherapy cocktails as an adjunct
- Polynucleotide scalp injection

- Low-level laser therapy caps, helmets and combs
- Blood-borne virus status and single-patient handling before any autologous preparation
Honestly
The evidence behind these is weaker than the evidence behind the medical treatment they sit beside, preparation systems and platelet concentrations differ widely between clinics, and response differs between individuals — so no particular outcome is offered. They are not used in a scarring alopecia, on an inflamed or infected scalp, or before a deficiency or thyroid problem has been corrected; any unregistered or unlabelled injectable mixture is declined whatever it is marketed as, and every autologous preparation is handled for one patient only with blood-borne virus status recorded beforehand.
