Dr. Gary Linkov, a facial plastic surgeon in New York City, says that most people will need a consultation, followed by at least two to three treatment sessions. At your consultation, you'll determine the treatment area, pigment color choice, and number of sessions needed. Your scalp will be assessed, and your provider may recommend that you shave your head (unless you have long hair you want to keep). Â
Prior to every session, make sure to wash your scalp well. You wonât be able to wash or wet your hair (including sweating, swimming, or using a steam room or sauna) for at least four days post-treatment.Â
Your provider should start each pigmentation session by applying a topical numbing cream to your scalp or injections of a local anesthetic, to ease the pain. "Numbing cream typically does not work for scalp, so you may need numbing injections," says Dr. Pak. Your provider will then use a microneedling device to inject pigment that looks like hair folliclesâeither across the whole scalp or in individual patches, depending on your goals.Â
The first appointment is usually the most conservative, since itâs when most doctors map out the hairline. âIf you prefer, you may even have a sample patch done so you can see what it might look and feel like before having the full treatment,â says Dr. Sara Wasserbauer, a hair restoration surgeon in Walnut Creek, California.
At the second session, your technician will drastically increase the density of tattooed hair follicles. You may need a third session, even if it's just for tweaks and a hairline adjustment.
Depending on the size of the area being treated, one session usually takes four to five hours. On average, people need anywhere from two to four treatments, spaced a few weeks apart to allow for healing.Â
RealSelf Tip: Anyone who doesn't have a fully bald head and wants a natural look should have the pigment applied behind their existing hairline. âIt can be used to add a look of density at the hairline, but the dots would need to be placed behind the hairline and not in front of it,â explains Dr. Wasserbauer.
