Elixir Ultime Masque revives the natural strength of hair while providing nourishment deep into the hair fiber. It gives hair ultimate shine, but leaves hair feeling weightless. It penetrates to the deepest part of the hair fiber. Use Elixir Ultime Masque by applying a quarter-sized amount to the mid-lengths and ends of the hair. Massage throughout, paying close attention to the ends and comb through for even distribution. Leave on for 5-10 minutes and rinse thoroughly.
