    Great product

    Complimentary from vegamour. I liked this serum! I’ve tried others and they usually have strong smells and this one doesn’t have a smell at all and doesn’t make your hair greasy or anything. I noticed results and am excited to see more!

    Amazing

    I used this for three months. I really see a difference. I have less shedding and I see hair growth. My hair is stronger and hydrated. A little bit goes the long way. It’s a real good scalp treatment. I keep it by my toothbrush so I can easily remember to put it in my hair.

    It works

    Gifted by Vegamour in exchange for my honest review. I have used this serum for about 2 months everyday once a day and have noticed a lot of baby hairs grew along my hairline. I haven't noticed much density, but maybe I need to use it longer to see better results. I like that this serum contains plant based ingredients, the texture is watery and does not make my hair oily. I apply one full dropper on my towel dried hair on the roots of my hair all over the scalp, I massage it in a little bit. I like that it does not make my hair oily and absorbs fast
