In my experience it is best to not try to dye your hair if it has not been washed within the last 48 hrs., especially if you sweat a lot, because dirt etc tends to cling to oily or sweaty hair which causes the dye to not work properly. It is the same with hair that has product like gel or hair spray in it. You could try it but I would not guarantee it would work. It would possibly come out splotchy.
The longer your keep the dye in, the more it will damage your hair. Follow the instructions, closely. ;)
yes
i don't see why not..
It won't take. Synthetic hair is made from acrylic or plastic.
Yes. It is possible.
It's okay. Having dark hair should not stop you from dieing it any darker or lighter.
Okay, you should not perm you hair right after you dye your hair because you will be damaging your hair even more and the damage you are causing on your hair already will be increased.
they become sweaty because they are blatently not okay to eat and are off
any age is okay, if you are young then parents should approves
You can dye your hair however you like, I don't think it would screw up your hair any way
I have dark hair but know hair pretty well. For example, my friend had blond hair and died it to brown. When you dye hair, the old color goes down to the end of your hair, so it will be lighter on the bottom. If you wash your hair the color will get lighter. If you dye your hair darker when it's light, your hair will be different shades and the dye usually doesn't stay in long. Also dying your hair that aggressively isn't healthy for your hair.
okay so you cant dye hair exstentions even if they are 'human' the reason for this is that there'll always be abit of synthetic fibre added in which cannot be dyed as it doesnt have the same properties as human hair
