Assessment is reduced somewhat dubious composition, unfortunately. Diazolidinyl urea - a substance extremely useful to humans and is not used in Europe. Nevertheless, it is possible that buy this shampoo more than once, and even advise (with reservation) familiar. Dry hair at the tips, porous, frizzy and quite greasy at the roots - shampoo works for a solid four. But oil masks, which are essential to me, washes 5+ like shampoo still have to search. In general hair great washes, it makes silky and crumbly. It works perfectly together with air conditioning and masks. When applied effectively refreshes the scalp, it gives a general feeling of purity, freshness. Pleasant fragrance, a combination of mint and green tea, very natural. The effect of clean hair is preserved approx. 3 days (depending on the mask used). Please note that if splashed in the eyes - they burn incredibly, applied and washed off better with high head thrown back, as easily gets into the eyes and cause discomfort, however, lasting just a few seconds. With a total combination of quality shampoo and it went very well, especially for those who like oil treatments and masks.
