Root Boost by Babyliss
This product is supposed to be the alternative of 'combing your hair back' to get more hair volume. You shouldn't comb your hair back as it would cause a lot of tangling and hair breakage. And I don't think that burning the roots of your hair to get the same result is a better solution. that's why I'm a bit hesitant about getting this product.
But I think that the result of using this root booster is much more better, it would stay longer and you won't need hair spray.
I love the volume, but I've burnt my hair enough :(
