What are some good heat protectants for blow drying your hair?

Ok, so I've been taking better care of my hair. I've stopped straightening since it doesn't really need it and cutting it regularly. I blow it dry though and I notice some of the strands are getting really brittle and it's losing it's softness!! It makes it frizzy and some strands are bent at the ends or look really kinky:/ any protectants?! I have to blow it dry everyday!
