Keep hair colour top of mind with this Bumble and Bumble Colour Minded Conditioner ($34). When hair is dyed, each cuticle is opened up so the colour can get into the hair shaft . . . but if it's not sealed back up properly, water enters and washes away new colour as soon as you wash your hair. This conditioner bonds to resurface each cuticle and seals them up so there's actually little-to-no washout or fading after all.
