First of all, the No Yellow line is SSOOOO GOOOD guise- it's the strongest, most even, easiest to use texture and formula of purple-based shampoos and conditions that I've ever used out of the half dozen I've gone through! The Foam Conditioner is especially amazing for it's super light texture but super strong delivery on the color correction- very easy to spread and smooth and also only takes 1 minute to process compared to 5-20 minutes on other toners I've tried!
This is the first No Yellow line I tried and fell in love with! The formula is much more liquid than other purple shampoos I've tried and lathers sooo easily throughout the hair in between the suds! I also find I get a very even coating of color correction when it comes to lathering through because of the formula's viscosity compared to thicker shampoos that would just cling to one area!
