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

great product, easy to use

Nice quality product at a reasonable price. Thank you.

Does what its supposed to do. I worked at a salon that carried this brand and it works just like it.

Huge bottle and great price for the amount. Only thing I don’t like about it is when I have hair up in foils, the oil drips after a while and it gets kind of annoying.

have used this product for many years!

Llegó en buenas condiciones, sirvió para lo que fue adquirido.

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

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

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.

Great for igora permanent dye. Brings a lot
