Rated 5 out of 5 by from Essential Behind-the-Chair Heat Protectant Moroccanoil Perfect Defense is an absolute staple at my station. It gives reliable thermal protection without weighing hair down or leaving a greasy residue, and clients always ask about the incredible signature scent!

Rated 1 out of 5 by from Left my hair stiff I was excited to use this as most of their products have worked well, but this one leaves my hair stiff as if I have used hairspray before drying my hair. I tried it twice and both times my hair was left as if I had serious split end issues (hair was recently cut). Not for me.
