No I dont take any vitamins, did not eat anything different so it must be the henna. I was thinking the same thing about how quickly stuff we eat gets absorbed into our system! The urine color is back to normal now that I have washed the henna out. I am super happy with the color and the condition of my hair. Knowing that the henna is natural and not a chemical product makes me feel good. Just thinking about the chemical dyes and relaxers I have used in the past and knowing that they must have also been absorbed into my system is scary.
I use Kinky Curly Knot Today and Kinky Curly Curling Custard. My daughters are 3c and 4b.
