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

This brand is AMAZING!! Ive been dyeing my hair for years (gray) and I thought I had a good product with Ion at Sallys. Schwarzkopf out-does every product Ive ever used! It mixes like a dream...quickly and smooth as butter. The smell is very nice too. I highly recommend it!

When in times like this when we cannot go to our stylists and we must do it ourselves! Thank goodness for supplies that are available online.

Amazing quality results!

I’ve been using the product a long time, it’s working perfect . Only thing will be better if has a measuring cup

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!

I cannot tell if its different than other similar developer. But I used with the hair color as recommended, the result is great.
