So I got hair dye, plan to do it today or tomorrow. So when I'm doing it should I keep a window cracked or what? How…

i dyed my hair outside, took my large mirror and a chair anf a small table

I did mine inside just make sure the room you're in is ventilated. Keep the door open or whatever. I do mine in the bathroom and just leave the door open

I opened a window and kept the bathroom door open with a small fan. Hardly smelled the dye

Wear a mask over ur nose n mouth like they do at hair salons. Keep ur door or window open anddd most imp .. Make that that hair dye says ammonia free
