Schwarzkopf Professional Igora Royal Developer 6% / 20 Volume 33.8 oz

have used this product for many years!

I used this with the Schwarzkopf Igora Vario Blond - Extra Power, and it worked great. No matter what bleaching product you use it will damage your hair in some way, but this didnt damage my hair nearly as bad as all the other bleaching products Ive tried in the past at Sallys. Will definitely order again in the future.

The product performed better than I expectd

I have used this hair coloring for over 10 years. Mix equal parts of color and developer, place it on your hair, leave in for 30 minutes and rinse. So easy to DYI. No more expensive salon prices.

Works well, stays put, no dripping

have been using for years!

Great. Worked perfect!

You can use this in several applications its alot of the product which made it a great value deal for me.

Great product it’s my go to for developer and quick shipping!

Great product! You get so much product for the price, I dye my hair quite frequently, and I have yet to buy more developer.
