Platelet-rich plasma (PRP) is blood plasma that has been enriched with platelets. PRP is rich in growth factors, so when PRP is applied to the scalp it can contribute to hair growth.
After PRP is made, it is injected into the scalp where the hair is thinning, so it can trigger the body's natural healing instincts. Research indicates that PRP promotes hair growth by stimulating hair follicle stem cells. The platelet growth factors induce follicle stem cells to shift from a dormant state to an active state, and that starts the process of hair production.
PRP for hair restoration is best for patients whose hair is starting to thin. Patients who have active infection on the scalp, diabetes, and are on blood thinning medications are not good candidates for PRP.
Scalp micro-pigmentation is essentially the process of having your scalp tattooed with tiny dots that resemble the appearance of hair growth. It's touted as an immediate solution to hair loss or thinning hair and there's no invasive surgery, no scarring and no down time.
Scalp micro-pigmentation offers to a totally bald man the appearance of some hair and an approximation of a hairline. It can also be used to camouflage transplant scars or to shade small areas where hair is thinning to make hair appear more dense. It’s also a good option for people suffering from alopecia universalis.
Scalp pigmentation doesn’t penetrate the skin as deeply as normal tattooing and the color can be matched to your previous hair color and skin tone. Unlike tattoo ink, it also retains its color – so patient will not start off with black dots and end up with a lighter color then years later. Even though the procedure hurts less than a regular tattoo and certainly a lot less than a hair transplant, anesthetics are available to numb the patient's scalp prior to the procedure. The treatment is permanent, and if patient is starting to go grey the treatment can be touched up to match.
