    Best Hair Serum

    This is by far the best hair serum I've used. It's a dual pump that pumps a cream and gel out together. It works to soften hair and can be used as a heat protectant. You only need a little product as it goes a long way, and it has a light, pleasant scent to it as well. The product does not advertise to be "clean," but it does contain a silicone ingredient, anti-mold ingredient, and fragrance, which can irritate some people. This is a staple in my hair routine and worth trying out if you need a new serum for your routine.

    Miracle Hair Serum

    For someone that has fine, highlighted hair, this product is a miracle worker. It takes my dry hair and leaves it feeling incredible soft and healthy looking. I have medium to long hair and use 5 pumps all over my damp hair before blow drying. The scent is soft yet leaves your hair smelling like you just came from the salon. Once dried there is no oiliness, only soft, manageable hair.
