My long, frizzy hair could get greasy again after just 12 hours, and I've tried countless products against greasy hair over the years. I've probably spent tens of thousands of kroner on useless dry shampoos and various products. Since I got this, I've saved so much time and money. Yes, it's expensive, but it really does the job. My hair truly feels freshly washed. I've saved so much time since I got this. I never have to wash my hair after working out, I just use this. So now I wash my hair 2 times a week.
