This is my first time trying organic Soeff treatment. I was interested in purchasing it because it is cruelty-free and vegan, free of animal-derived ingredients. The glass container is safe, and since it contains organic argan oil, it was highly effective even for damaged hair. I could visibly see my hair becoming smoother in an instant after using this treatment. It felt moisturized immediately after rinsing, and the scent is lovely, with a subtle citrus fragrance. I recommend it.
