i have really long, thick hair that tends to be a little dry, and i color it every six or seven weeks. i want to use hair masks and deep conditioning treatments to make it more healthy and to make it really shiny, but i was wondering if using two a week would be too many.

i bought this one because i color my hair: Frederic Fekkai Technician Color Care Mask.

and i bought this one because i've heard it's good for improving the health of your hair and making it shiny: Oscar Blandi Trattamento al Fango.

if i use both of these during a week, a few days apart, would it be bad for my hair? should i alternate between using them every week, like one of them one week and the other the next week? or should i just stick to one?
