What can I say about this shampoo... definitely only negatives! I bought it because once (2016-17) it actually helped my hair (dry, frizzy, and dyed hair), now I have been using it gradually for a few months because I wanted to give it a chance, but it makes my hair crazy... dry, unruly, as if I am using dish soap... the only positive is its scent, which really makes me feel like it cleans my scalp perfectly. My hair doesn't get oily quickly at all with this shampoo, but what's the point, the overall result is terrible. I wish the quality would return to how it used to be

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!
