Matrix sleek look iron smoother, protects hair up to 450 degrees, has a light smell, and has a memory locking component that basically helps style your hair. If you get a hard feel it's easily combed out. I've tried the tresemme, smells wonderful, but I don't feel like it really protects my hair. I got MAJOR split ends using it, and it doesn't say how high the temperature protection goes. If you want a drugstore brand, try got2b
