Thick hair doesn't tend to look or feel oily as quickly as fine hair, largely because those coarser strands are able to soak up more of the sebum from your scalp. So, if tresses are thick, hair wash day can happen every three to seven days. Some people with coarse locks may find they can go even longer, but we recommend they don't for the sake of the scalp.
As for the type of shampoo that’s needed, we recommend Oil Reflections Luminous Reveal Shampoo ; a lightly moisturizing wash that gives the dry lengths of coarse locks a boost of healthy shine. Packed with camellia oil and white tea extract, it pairs perfectly with Oil Reflections Luminous Smoothing Oil for a radiance-enhancing routine that leaves thick manes silky and soft.
