Is it normal to use shades of brown in scalp micropigmentation for Asian hair?

There are many doctors or SMP clinics that offer different color SMP.  It is all based on each clinic's' protocol.  You may want to ask to see their former patients. 

Hello eguo4554Have you looked into a second opinion? I don’t judge the aesthetician opinion, but so far my micropigmentation expert utilizes only black pigment when it comes to asian patients. The results are very good.I will recommend you to discuss this with your current aesthetician and/or look for a second opinion.

It depends on the types of ink the provider uses.  Some semi permanent colors will have different coloring recommendations.  Typically a permanent coloring with different dilutions of black ink is used and the dilution about depends on the patients skin tone, etc.  If different colors are used, you should ask how that color holds up over time.  Black pigments fade to shades of grey over time, which works well in most patients.  Good luck!
