My hair started falling out, drying out and getting frizzy once I started going through menopause. I was looking for a more natural ingredient shampoo and my sister told me about Hask Keratin Smooth shampoo. This has been a game-changer for my hair. My hair looks healthier, softer, and hydrated and I have a lot less frizz. Not only does it lather well, but it also has a nice scent. I have hair down to the middle of my back and it doesn't take much shampoo to wash my hair. I follow up with the Keratin Smooth conditioner as well. I would recommend this brand!
