Yup it's safe. Just got mine done. (Highlights and lowlights) 2 weeks ago at 15 weeks.
they say your safe after 3 months. dyed my hair a week after being 3 months(: my hairstylist said its fine, just not before 3 monthss
Its fine i was bleaching my hair the first two months and recolored all of it after. They say its fine the only thing that would be bad is inhaling a lot of fumes so if you're not a hairdresser you're good :)
As well as its ventilated your good just got mine done yesterday. I'm 21w 4d
It's totally safe in a well ventilated area. I'm a hairdresser, so dye jobs are an every day thing for me, and my doctor said I was completely safe doing my job, so if I can do it almost daily, it should be fine for just about anybody. To be extra careful, try to get the hair dye that's ammonia free. The less smell, the better off you'll be lol
