The desert date is well known for its high concentration of fatty acids and proteins, which lends its beneficial properties to help repair hair. The wheat protein hydrolysate reinforces the structure of keratin while the cationic repairing agement repairs and soften hair. The conditioner is applied after using shampoo and after leaving it on for 20 minutes to be wash off. I love how soft, smooth, and manageable my hair feels. This is one the best hair mask I have I used.
