### ⭐⭐⭐⭐⭐ Love it, it works as it should.
*by A***D on 20 July 2022*

I bought the whole Redken series after spotting it at my hairdresser, she mentioned my hair being dry post highlights and she used that on me. Great thing about this product is, it contains this Violet/blue thing which stops your blonde going egg yolk like in colour, the only inconvenience is you need to leave it on hair for 5-15 minutes, this is an issue if you are in a rush and just want a quick shower so plan your hair routine in advance so you got enough time to let this product work. Results: hair are soft, moisturised, shiny, less frizzy if you use it in combination with the rest of the series you will be super happy with results.
