This deep conditioner is an ultra restorative, moisturizing treatment that will rejuvenate dry, damaged, chemically treated or over-processed hair. Macadamia oil, native to Australia, is known for its absorbing, deep penetrating and cuticle-sealing qualities and for leaving even the most damaged hair soft and nourished with incredible shine. How to Use? Apply a generous amount of Macadamia Oil Hydrating Deep Conditioner to clean, wet hair. Massage into hair focusing on damaged areas. Let penetrate for 10 minutes. Rinse well. Style as usual. For best results, finish with HASK Macadamia Oil Exotic Shine Treatment.
