leaves my hair smooth and silky [SEP] opulent has absolutely surpassed my expectations with their argan oil shampoo from the amazing salon quality scent to its extraordinary hydrating results there is no way i can go with any other hair care brand i have been on a long endeavor to find sulfate free shampoo that is affordable and not loaded with chemicals that easily dry hairmy only qualm is that it reacts strongly to humidity while it can be nice to observe added volume it is not the greatest to observe noticeable waves to recently straightened hair i have not had this problem too much since i am from a fairly dry environment but heading out to more moisture rich areas definitely highlighted the change i first noticed this in the bathroom where i otherwise never had this problem before airing out the area proved to be helpful but if i stepped outside when it recently rained it would of been better to let my hair benow the moisturizing effects are wonderful i noticed a difference in shine and thickness in my hair and enjoy how soft its been getting this is a wonderful product i received to review and will definitely be using it in the future
