Hi, i had a global keratin blow dry 2 days ago and it took a lot of the colour out my hair (it was a semi permanent so kind of expected it) it's went really warm looking now and i much prefer it to be more ash. Had a colour touch 5/1 on. It's went a lot lighter too. I like it lighter, just don't like the warm tone. I was wondering if I am able to get it coloured or will it affect the straightness?
