ion Bright White Sensitive Scalp Developer 10 Volume, Vegan, CrueltyFree, ParabenFree, Infused with Plant Proteins, Argan Oil, Aloe Vera, Coconut Oil, 4 Ounce

Easy to use and works quick.

I have colored my own hair at home for many, many years. I've tried so many different developers over the years, but Ion bright white for sensitive scalp is probably the best I've ever used. I think I've been using it for a year or more and I don't think I'll ever use another brand. It works for me. My scalp is never itchy or sore when I use this developer with my hair color.

Very good developer! Smells amazing and leaves hair silky and shiny!

Price was quite high for the size. Same product can be found elsewhere for fraction of the cost and similar quality products of other brands are cheaper here on Amazon. I did work well on hair, but definitely not enough for a full head of medium length hair.

I was doing a test strip on my hair and the developer smells like shampoo. I have other ion developer from an actual beauty store and those smell different so I’m a little skeptical with this one off Amazon.

Changed the color of my hair. I had it colored less than one week prior to this treatment. Disappointing.

I bought this to make my hair whiter and remove some yellowish, but it only made it gray. Do not buy this product if you want to keep any white here.

The media could not be loaded.  Would give 0 stars. Developer spilled and leaking everywhere . knowingly sent a defective product. How could you think a single piece of tape would hold together a broken cap?
