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

have used this product for many years!

This is an excellent product. It does work very well. Moreover, it didnt really come with instructions, that is a bummer. I had to go to YouTube to see how to use the cream and this product at the same time. Meaning I had to mix them. In addition the huge problem was how much I had to mix. But overall, the results are very satisfying. Thanks, Laura

the developer works great and fast

its exactly what you would expect for developer

I really like Schwarzkopf professional products. They leave the hair in really good condition.

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

I do color my hair every 4 weeks and that is good for whole year ,so I don’t have to run out often.Until I will color my hair I will use it.

Good quality, great price

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.

This is the best developer I have ever used. Quick, effective, no brass tones. Super happy with the results I think I’ve fiballt found my go to!
