If there’s one product every blonde needs, it’s a purple shampoo! Blonde hair goes through a lot (especially if you’ve recently bleached your hair!) and it can sometimes look yellow, dull or even brassy. Purple shampoo, or sometimes even silver shampoo, cools down the tone of your hair and neutralises the brassiness, keeping your blonde stronger for longer. While there are many standout blue 'poos on the market, Matrix Brass Off shines above the rest. Formulated specifically for lightened brunette hair, this sulfate-free hair wash deposits blue-violet pigments to minimize brassiness. In other words, it creates a stunning cool-toned finish that brings out the intended effect of your color-treated hair. The vanilla-rose scent doesn't hurt either. For dry, damaged, frizzy hair in need of repair, our Miraculous Recovery collection nourishes and smooths for healthier-looking and feeling hair. Expertly-formulated with Anti-Damage Technology and nourishing oils, this range helps visibly repair damage, reduce frizz and help to seal split ends for shiny, smooth, hydrated hair.

Let it sit for more toning power. To help achieve a cooler tone, let your blue or purple shampoo sit in your hair for 2-3 minutes after you suds up. If you’re experiencing extreme brassiness, you may want to leave the formula on for longer.Frequency of Use: Most blue shampoos are intended to be used two or three times a week, which is the case with Not Your Mother's Triple Threat Brunette Blue Treatment Shampoo, though weekly use is often plenty.

Brunette hair has more melanin than blonde strands, when it's lightened (in the salon or by the sun) the pigment is removed, resulting in a warmer or copper tone. Which may be perfect for the summer months but if copper isn't what you are going for, then a blue shampoo may be your answer. This ground-breaking collection infuses brunette tones to blend away unwanted grey hairs into natural-looking brunette. Formulated with coffee extract and GreyBlend technology, our Defy Grey Shampoo gradually blends away first greys by infusing warm brunette tones into grey strands for a naturally-blended brunette look, effectively disguising greys.
