    Reduced shedding

    I have fine, low density hair that tends to shed a lot. The biggest change I've seen so far from using this serum is a decrease in shedding so im excited to see how else this transforms my hair. I also love that it's lightweight so it absorbs quickly. One dropper full is definitely not enough for coverage though so I wish it had more product. Complimentary from Vegamour.
