Basically I've never bleached my hair before, however I have been straightening with a flat iron about 2-3 times a week for the last five years, my hair is naturally a bit dry and pretty wavy and the ends are slightly damaged from heat styling. Tomorrow I'm going to the salon to have them bleach and colour my hair a chestnut brown (I naturally have asian black hair that comes down to my waist). I'm going out to dinner a few hours after the hair dressers, is it safe to straighten it once I get home or will I ruin the colour/bleach somehow? Or damage my hair even more? Sorry if these questions seem obvious, I'm a complete newbie when it comes to hair treatments!
