PRP
Platelet-rich plasma for hair and skin, prepared from your own blood and sold per session.
PRP takes a small amount of your blood, spins it, and injects or applies the platelet-rich portion. Clinics offer it for thinning hair and sometimes for skin texture. Hair is the use on the hair loss concern page, next to exosomes.
It is a course. A single session price understates what clinics usually propose. Ask how the sample is prepared and how many sessions the quote assumes.
Downtime
The draw is a blood test. The scalp or skin can be tender and pink for a day or two. There is no donor product involved.
