9. Can hair coloring give me a dry and itchy scalp
No, but coloring should definitely be avoided on scratched or veryirritated skin conditions, because it could get worse.
10.I don't want to use peroxide or ammonia. What else can I use to color my hair?
To obtain natural-looking hair color, peroxide and ammonia are needed, because without these ingredients your color will not take as well,look as good, or last as long. If you take sufficient care before, during and after the dying process, there is no reason why you shouldn't have the best of all worlds: beautiful, long-lasting color and well-conditioned hair. Bur if you dont want to use them then you can use vegetable colors such as henna or camomile.
