I used this on my medium blonde hair and it removed the yellow tones perfectly. The hair feels stronger and looks brighter after just one application. The shine is natural and not overdone. I’ve noticed less frizz and smoother combing since using it.

Great for balancing out warm tones. The color retention is impressive—still looks fresh after two weeks. Hair feels healthier, though it took a few applications to see the full effect.
