Never really used it much. But with having thick hair I'd love to go longer than 3 days before washin it. I could get away with it as my hair is thick and it never looks greasy. However it feels greasy and my scalp itches so i cave in and wash it.
Would dry shampoo help the itchiness. In the past when I used it I always found it powdery so had to wash it the day after anyway. So only got one day extra is it worth it.?? Just be great to go longer cus of my hairs natural oils etc
