This brand of dry shampoo is not one that I will ever buy again. This is why: I purchased this on a whim. It was on sale and I was out of dry shampoo. I usually wash my hair every other day, so I wanted something for the in between times. I used this dry shampoo the next day and it was terrible. The dry shampoo by Pssssst left my hair looking weird and clumpy. Also, it did not help with my oily roots. It actually made my hair looks less clean than before. The dry shampoo also gave my hair a strange texture. I was late for work, but I ended having to shower anyway. It was very frustrating because I really did not have time. I noticed that my hair also seemed look way more greasy as the day wore on. I would not recommend using this product. I have purchased other brands of dry shampoo since then and none of them did this to my hair. Effectiveness This dry shampoo effectively made my hair greasier instead of cleaner, which is the complete opposite of what it was supposed to do.
