This question is for my sister! Shes the only one in the family who doesn’t have blonde hair. She’s starting to get some gray hair growing in and would like to cover it. How is this done? For my mom (who is blonde) it’s taken care of when she gets a weave. My sister does not currently color her hair. Is this best handled by a stylist? At home? With a whole hair kit? Highlights? Roots touch up? We’re complete newbies here. Thanks!!
