I have to be real honest with you. You can wash your hair with warm to lukewarm water, which is a good thing. But I would not use heat from a blow dryer for a few reasons. 1. The heat will dry out the hair's natural moisture, and 2. it is more damaging and puts stress on the hair itself. If I were you, I would avoid putting heat on the hair; maybe, air drying your hair would be a better choice for you. But if you decide to blow dry, make sure the heat setting is on warm, and not on hot. And use a heat protectant spray to avoid possible breakage and split ends.
Hope this helps you a bit.
