    Reviews

    If you are looking to transform your hair...

    Every time I use it over night, my hair looks so good the next day I forget I even considered to wash it out. It contends with Moroccan oil and is a lighter product. A little goes a long way, 2 pumps over night. One pump for the SMOOTHEST, light feeling hair ever. If you are looking to transform your hair, start incorporating this product ASAP, you will see changes instantly.

    Game Changing

    The FoB Hair Serum is a complete game changer for me. I live in a part of the country where we have all 4 seasons. This serum keeps my hair smooth and frizz free without being heavy or greasy. It works for the swampy humidity of summer and they dry cold winter.

    My all time fave!

    Why do I love this serum so much? As a curly hair girl who has had very damaged hair, this serum has been my bestie when I wash my hair. It always makes my curls look healthy and beautiful. I also love to use it when blow drying my hair as well, since it gives it shine and makes it look super healthy.
