"I truly love Shu Uemura Essence Absolue Oil ($69) for all its versatility! It can be used as a leave-in conditioner on wet hair before blow-drying, on dry hair for added shine and control, or, my favorite, as a routine moisture treatment for a healthy hair boost. Just apply on dry hair before showering and leave it on for at least 15 minutes, then follow with your usual shampoo and conditioner." — Kattia Solano, master colorist and owner of Butterfly Studio Salon
