    How to Use

    Apply 4 doses on dry or towel-dried scalp, section by section.
    1 dose = 1 pipette until the mark.
    Do not rinse.

    When choosing where to apply the sèrum think of the areas of your scalp where the hair needs the most strength. Where do you notice less density? What areas are you experiencing hair fall in? Start by applying in those targeted areas with the pipette then massage in everywhere. Think of the serum like topical vitamins for your hair!

    Rated 5 out of 5 by from I can see and feel the difference I've seen a real difference in the strength of my hair since I began using this product. My hair is thicker and stronger, overall a lot more healthy. I would definitely recommend it.

    Rated 5 out of 5 by from Genesis / hair confidence I purchased the entire genesis package, shampoo, conditioner, serum and Thermique. The serum makes my hair strands look thicker, my hair looks thicker and my hair color isn’t fading. Genesis products have made a huge improvement in my hair. I wasn’t born with tons of hair. So I am very happy.

    Rated 5 out of 5 by from One of my favorite One of my favorite hair products of all time! This serum is extremely lightweight, perfect for weekly use, it smells amazing, and I would say it’s great if you tend to have frizzy hair ✨

    Rated 5 out of 5 by from Helps grow hair This product makes a difference. Approximately 6 months ago I cut my hair, because my ends were unhealthy. I wanted to grow healthy long hair. I normally do blond highlights every 3 months and blow dry my hair often because it’s frizzy and fine but I like to keep it straight. I liked the serum because it does what it supposed to do. I noticed new hair growth, less breakage and overall healthier hair. I used one pipet once per day and just massage it my hair.
