Definitely worth the $
I have only used this a few times but even after first use I noticed a noticeable difference with way less frizziness. (I have fine, thin and frizzy hair. Good times.). So I’m sure it’s good for heat protection but this was added bonus.

Game changer for my hair routine!
I absolutely love this product! Yes the scent is strong, but I enjoy it and it doesn’t linger in my hair for long. I use it on damp hair before blowdrying and it makes my hair so soft and not frizzy at all. It is not greasy at all and I have thin hair.
