Schwarzkopf Professional Igora Royal 6-0 permanent hair color product gives dark blonde color by combining Color & Care Developer and Color Crème. This combination gives ideal color equalization, fortified hair structure with perfect coverage, lasting shine, and protection from ultraviolet rays and pollution.
The product has a proven record of mixing twice as fast as those of other brands. For using shades with coverage of up to 100% white hair, you need to mix 3%, 6%, 9%, or 12% developer in the ratio of 1:1. Then, apply this mix to your dry hair and let it develop for 30 – 45 minutes. After that, you should rinse your hair well, shampoo it, and neutralize using a product belonging to the BC Bonacure Color Save collection. For darker color, consider the 3% Color & Care Developer. Similarly, consider 6% developer for 1 tone lighter shade. For coloring 1-2 tomes lighter, rely upon 9% developer and for 2-3 tones lighter shade, go for 12% developer.
