If I had to pick only one shampoo to use for the rest of my life, it would be this. This is the shampoo that I go back to time and time again, the one that I’ve repurchased at least five times since first discovering it, and the one that never lets my hair down. It cleans my hair thoroughly without leaving it feeling stripped or dry, and it has a lovely fresh scent that lingers on the hair for quite a while after rinsing. I wash my hair every day and this is gentle enough shampoo to use that often and it always leaves my hair feeling soft and silky. If you’re worried about the price point trust me, I feel you; but a little bit of this product goes a long way so I wouldn’t be too concerned about getting your money’s worth. I use the number 1 version of this shampoo (for normal to slightly sensitised hair), and it is also available in number 2 for dry and sensitised hair. The Kerastase Bain Satin Shampoo retails for $39 and is available for purchase from StrawberryNet.
