I am a man with long hair down to my waist. For some reason, they started breaking very easily in the past year. I was losing a lot of hair every day, mainly at the point where I tied the elastic to put them in a ponytail. I bought Syoss because the bottle promised a 90% reduction in hair breakage. Instead, I actually saw a 90% increase in hair breakage! When I took off the elastic, half of my hair was left on it! I stopped using it after one month and bought the Pantene Repair & Protect range (shampoo, mask & conditioner), which worked fantastically, literally from the first wash!
