Should you apply a heat protectant before blow drying?
I've never blow dried my before and have been thinking about buying blow drier (with a diffuser of course). I've heard the heat from the blow drier can cause heat damage, but I've also heard that it doesn't. Should I buy and use a heat protectant before I blow dry or doesn't it matter?
I don't think you need it if you're using a diffuser but you could get it for procaution
