My hair (shoulder length, brown, straight, boring) is in a perpetual state of frizz. Unless I go to the gym, when I come out with it sleek and lovely. I assume it is because they soften their water, as the shampoo and conditioner they supply is fairly middle of the road stuff. I’d love to be able to make it look like that more often but have no idea how. Short of going to the gym more (I know!), how can I make middle aged hair look better?
