the minimum is 3 weeks; however most hairdressers will say 4 if you want your hair to stay stable and get optimum color. Also if you do it too soon, the color will not turn out as well as it could if you wait for healthy hair
about a month
I depends if it is a chlorinated pool. If so, wait 24-72 hours. If it is natural water, you do not have to wait.
3-5 weeks
2 weeks depending on how strong your hair is
If you get highlights, you should wait for a day or two. If you dye all of your hair, you should wait two to three days.
Yes.
You don't have to wait; it doesn't matter if u wait and do it a year from now or right this minuete. Your hair will just be more brittle and dry after dyeing the same part multiple times. Conditioner for dyed hair can help though :)
as soon as you feel you need to,but definitely wait until they look as though they are faded to prevent damage to your hair and dryness - about 6 months. If you have had a full head of highlights put in, 6 months later have a half head of highlights to top up or intensify :') hope it helped.
2 week or longer
redye orange of coarse
either dye the highlights to match your natural hair colour cut them out or wait for them to grow out
There shouldn't be a problem to get hair highlights, as long as you go to a professional. However, if you're hair is too damaged from previous colorations or bleaches, maybe it's better to wait until your hair is healthier or have a hair cut.
