Im acne prone and a lot of leave in hair products can end up causing acne, but this doesnt cause acne for me at all!
This serum is amazing for fine hair or anyone who doesn’t like anything too heavy! It is super lightweight...
It doesn’t weigh my hair down at all and adds a beautiful, healthy shine . A little goes a long way , so the bottle lasts quite a while .
Overrated- a bit sticky and no visible payoff. I really wanted to love this product, but for me it's overrated.
