Took two tubes of this on holiday with me recently to boost my coloured hair after being in the sun. The only positive I have for this product is that I only needed to use one tube each application it goes a long way, I have quite thick hair and when I self dye I need two packets for full coverage. When I first opened the product it was very orange and my hair came out with a ginger tinge to it rather than the red boost I was expecting. I use bumble products because they usually make my hair feel fantastic but after using this and following it with the Bb Colour shampoo and conditioner it felt sticky and heavy. Really disappointed I would have been better taking a cheap self dye to keep my colour poping and save some cash
