Schwarzkopf Color Boost Color Vibrancy Booster, Icy

I’m am growing out my auburn dyed hair to my natural ashy brown with silver highlights. My hair grows VERY slowly so this has helped tone down the brassiness of my dyed hair and helped to blend my natural growth. Will use again. 1st picture is AFTER using this product. 2nd picture is BEFORE. I applied to dry hair and left on for about 25 minutes.

Didn’t do anything… hair still orange

My hair is highlighted blonde on medium ash brown. I was looking for this (Icy) to leave a sheer cool soft ash tone to neutralize the brass. I left it on for 10 min, 5 pumps blended into conditioner and combed through evenly. The results aren't visible until the hair is completely dry. Then you can accurately gauge the results. I've decided I would buy this again but wish the color had a bit more lavender tone to it.

Really helps tone down brassy/redder color for brown hair

I have medium brown hair with some grey. This turned my hair close to black. It was also very difficult to get out of the bottle and made a mess of my bathroom. Fortunately, it washed out with my next shampoo. Not what I was expecting.

After I used it twice I didn’t notice much change in color ( wanted less brassy). However my hair and roots were more oily than normal within a day or two, when I normally go 5 days without oily roots.

I stopped coloring my hair last year and embraced my grey! This is a great addition and brightens my hair naturally.

Love the way it calms down brassiness and yellow!
