Every time I see posts with questions about "mixed" hair I roll my eyes and keep it moving. I think it is total foolishness to presume every biracial black/white person has exactly the same hair. What is "mixed hair" Lenny Kravitz or Corbin Bleau? Im not mixed and that little girl in the avatar could be my hair twin. My ex has two half asian daughters and their textures are nothing alike. A lot of people I wouldnt know were biracial if they didnt tell me. I have relatives who are 3s and not biracial. But companies are making a killing off people buying into this. I wouldnt get upset over YT comments. There is a white lady on YT with an adopted daughter who is black and she can cornrow like nobody's business.
Transition your mind before you transition your hair.
