It's box dye

I have: didn't do any damage. Just make sure you condition.
You can also strip out the dye you put in with Vitamin C. I've also done that, it works REALLY well.
You get Vitamin C tablets (in the vitamin aisle) crush them up and add them to shampoo. Cheaper shampoos with a lot of sulfate works best because the sulfate weakens the dye (why shampoos made for dyed hair have little to no sulfate in them) I believe I used V05 strawberry. Just something cheap like that.
You put it in your hair, put on a shower cap, let it sit for an hour maybe (I"m going to look up the exact recipe and post it here in a minute) and then rinse it out of your hair. CONDITION well afterward. Sometimes it takes a few washes with this but I was able to get years of dye after dye after dye out of my hair in one wash.0
