I use Bumble and Bumble Don't Blow It because I use so much heat on my hair to style it, from blow drying to flat ironing.
Although it can be a more expensive purchase, it does last a long time considering you are using tiny amount to get the job done.
It protects my hair without feeling greasy , is light enough that you can style your hair afterwards and has a nice scent.
Using is two or three time a week it has lasted me going on 6 months. Great product!

I bought the 5oz bottle at Sephora and I love this. It's a very silky hair creme that it leaves my hair soft!! It smells great, it does feel a little heavy on my super thin hair but it's not too bad. If I were to repurchase I'd get it on sale.
