I really like this product. It provides volume that lasts for hours. In humidity, some fullness is lost, but my hair doesn't flatten down like it would without using Frieda Volume. I especially like that it leaves the hair soft, not stiff and sticky. This is now my go to, flat hair, problem solver. It is easy to use and a plus is that you can do touch ups on dry hair. Just spray and dry with the hot dryer to renew fullness.See full review
