Oligo Professionnel Blacklight Blue Shampoo (8.5 Ounce) Protect Color Treated Hair | Extend Coloring, Lustrous Shine | Vegan Friendly

Best blue shampoo I’ve ever used. Hair actually feels healthier after, meanwhile every other brand I’ve used makes your hair feel dry or brittle. I used this on my light brown hair with highlights, and I really like the results. Will make this my regular brand.

Worked great!! I have light brown hair and had highlights on the end that had turned brassy and an overall red tone to the ends. One five minute treatment and my hair is shiny and the highlights pop.

This is an amazing product! I used Purple shampoo before and it never worked as well as this product! I e noticed that when I go days without using it, my blonde highlights look less vibrant and brassy. Continual use is a must but it's the best!

I rarely bother to write product reviews unless they really WOW me - and this product has done that. I recently painted highlights into my own level 7ish blonde hair and even though I used toner afterward, my roots still had some parts with a stubborn orangey-carroty hue. I've never used a blue shampoo before but came across this one and ordered right away based on positive reviews. I left it on for 5 minutes on my crown and roots, and 1-2 minutes on the lengths, which needed far less correction, I just wanted to make sure the entire look was cohesive. The results are PERFECT and all the orange tone is gone. I'm blown away by how well this worked! As other reviews have stated, it is a bit drying so just use a good conditioner or hair mask afterward and you'll be fine.

Blue shampoo is perfect for removing brassiness on brown lowlights
