    So far so good!!

    So far feels very nice on my hair. My hair doesn’t get oily too fast and it has felt a lot softer! I haven’t noticed a change in length yet but I am just starting out with it.

    Really Works!

    I purchased this product when it first launched back in September so it’s been around 6 months. My edges have grown so much which is where I apply the serum and foam and they look better than before having children. Post-partum hair loss really messed up my hair but this entire treatment has saved it. My hair just feels thicker too even my hairstylist has noticed. Will keep purchasing it because it truly works.
