BirchboxEsalon Heart Lock It Color Safe Shampoo

BUY at Birchbox

Free of harsh ingredients (we're looking at you, sulfates) and full of strengthening vitamins, this color-safe shampoo has us feeling like the heart-eye emoji. It banishes oils while nourishing strands to extend the life of hair color, which means your locks look vibrant and healthy between dye treatments. We're in love-and we don't care who knows it.
