Infuse My ColourMy. Cobalt Shampoo 250ml

This shampoo has a strong blue tint to it which certainly does its job at toning the hair (it also stains hands and nails, so be careful!). It managed to tone my very orangey-red dyed hair down to a much prettier and darker burgundy red. It also smells like apples, which is nice. My only issue is that it doesn't lather up much, regardless of how much of the product you use or how many times you shampoo your hair (anyone who shampoos their hair twice knows they don't need a lot of shampoo the second times and it lathers up a LOT). It's also pretty pricey for a product you need to use more of but I'm guessing that's down to the formula being vegan.

I am a brunette with ombre highlights which tend to turn orange or yellow after a few weeks from a salon visit. Now salon visit is impossible following the lockdown i frantically looked for at-home toner to cool my brassy bits down. I have tried several high-end purple/blue/silver shampoos in the past but NOTHING beats this God-sent Cobalt shampoo! No stain, no need wait for product to develop, no damage and the results are magical. I used it as instructed- shampoo twice and followed by my regular conditioner. My brassy streaks turn lovely cool ash blonde even when out in the sun. No red/orange/yellow tints anymore. The shampoo does not cover grey but subtly turns my grey to muted ashy silvery tone which I love. So far i have used it twice a week. Hair is super glossy and certainly looks like I have been to a salon to freshen my color! Will order another one now.

I had box dyed brown hair with reddish tones that I wanted to neutralise. The Cobalt Blue shampoo claimed to be able to do this but it could not. I used it loads, left it on for ages, tried everything but it failed and if anything, made the red tones more obvious

I bought this originally to tone my blonde hair but it turned my hair bright blue. I used too much product and left it on too long HOWEVER.... I ABSOLUTELY LOVE IT. I now have the most beautiful purple blue hair.

This is alright actually. Haven't had my colour done since before lockdown and I can see a definite difference after using it. I do leave it on the hair for a few minutes, for better or worse
