Dear Asha,
There are ways of looking at it.
1) If you are coloring for the first time it is advisable to go to a professional to do it.

2) May be you can recolor your hair professionally.
3) If it streaks of different color ensure your hairstyle goes with it and can make it look like highlights

I alternate between profesinal coloring and my own at home
May God bless you.
