I only use protein if I am having severe breakage and shedding. When my hair was pretty damaged I would use Aphogee every 4-6 weeks. I also like MT but can't say if it's a good protein for my hair. Anytime I used it I ended up with protein overload.
I like the way Aphogee works but hate the smell, the fact that it's runny, and it kind of burns and stings my scalp and skin. It even melted through latex gloves. Not sure if I had a bad batch cause I asked if anyone else experienced this, but unfortunately I got no responses.
