Would semi permaent dye ruin your hair??
Semi-permanent hair colour is less troublesome on your hair, as the colour it will wash out and not grow out as you find with permanent dye.
All hair dye is safe as long as your do not go over-board with colouring your hair..…. I have seen documentary on ladies who dyed their hair frequently when they were younger and end up being bald or had really thin hair at the top of their head or bald spots when they are old which is fairly scary if you think about it.
It doesn't ruin your hair unless you are using it too often. It damages your hair, but with the right hair treatment and time, your hair can repair itself.
