I don't know of any tips. People usually color their hair to cover gray, to look more fashionable, or to restore original hair color. Which is your situation?
For sure. Are you just ready for a change? The main reason people dye is for cosmetic reasons.
I'm thinking about coloring my hair soon, any tips?
The main reasons for this are cosmetic: to cover gray or white hair, to change to a color regarded as more fashionable or desirable, to restore the original hair color after it has been discolored by hairdressing processes or sun bleaching.
