I need to know if I can use Bigen powder hair coloring and touch up my hair on the same day? Also, am I correct that if I can color and relax on the same day, I should relax the hair first before coloring it?

You can relax and color your hair in the same day with a semi-permanent hair color. If you plan to use a permanent hair color, you should be apply it two weeks after the relaxer application.

It was partially helpful, I wanted to know specifically about Bigen powder hair coloring and relaxing the same day. It does not have ammonia or peroxide in it but the box says permanent hair coloring
