I will share some bad experience with you guys.
Some one told me I tried this I thought of changing my colr from black to low golden just like the burgundy.
After I used it.my color changed and it was effected on the sunlight but it overcome with a lot of disadvantages.
It started loosing my hair and my hair got rough and hard.All my hair started loosing within no time
I STOPEd it even it created fuss to my hair style.
They use bad chemicals in this product just to damage the hair.
So its better be safe and dont use this product.
