Does blonde hair need taking care of differently?

Someone said the other day that because I had blonde hair, it was always going to get damaged because it was bleached and stuffed and not 'natural'. Is that true?? Do I need to take care of differently to say people with red hair, brown hair, or black hair? Cause at the moment I do not use a hairdryer, I wash it about 3 times a week, deep condition once a week, I don't straighten it ever, if I curl it which is rare, I use heat protectant, I use good quality shampoo, a detangling spray and split end prevention cream. Is there something else I should do because I'm blonde to make sure it's healthy and luscious?
