Hi ladies:
I have been reading everything thing I can find on the Keratin smoothing treatment. I still want my curls, but I live in 90% humidity year around and I have finally decided to give it a try. I haven't read anything on whether Kerartin mixes well with henna. I am more than 50% grey and I have been coloring my hair with henna and indigo for a year now.

Does anyone know how the Keratin will affect my color or if the henna will spoil the keratin?
thanks--
