Every morning when I brush my hair, I don't see any clump of of hair anymore. Similarly, I lose almost no hair if I am washing my hair with plain water. With shampoo, I do lose a little hair but that's ignorable compared to what the situation was before. The product is non-sticky and has a lovely mild scent. It may or may not weigh down the hair just a tad bit probably depending on what type of hair one has. There is no need to use shampoo the next day.The spray is easy to use.
