This shampoo is really effective against dry and damaged hair in particular by the sun. From the first application, we feel fed and protected hair. There as a protective balm on it. The hair is soft to the touch and light. For your information, I have colored hair / streaked and they tend to re-grease. Another point to highlight the next day the hair is not too ratapla and are not bold. (For those that have a nature quickly regrease) The smell is very nice too.
It only takes a small amount to wash the hair (personally I have medium length hair). By cons, and as indicated on the bottle, rinse it really well.
Really effective, well protects the hair I recommend despite a somewhat excessive price.
