Agadir Argan Oil Treatment does just what it says it does--it conditions damaged hair and gives your hair shine. It also protects your hair against from heat from blow dryers and flat irons. I have long straight hair, and use Argan Oil on my damp hair after shampooing. It helps to tame my hair and make it more smooth. Plus, I feel less worried about blow drying my hair everyday and using my straightener. You can also use a tiny bit of Argan Oil on dry hair to smoothen, add shine, and prevent fly aways. I would caution not to use too much or it will weigh your hair down and make it look greasy. Also, if used every day it builds up in my hair so I have to use a clarifying shampoo to make sure I get all product residue out. You can also use this as a mask--work through wet hair, wrap your hair in a towel (or better yet a plastic hair cap), leave on for a few hours (or overnight if you can). Then you shampoo your hair; hair is softer, shinier and healthier.
