    An absolute must have in my daily self care routine

    I started to get serious about my hair care specifically scalp care. Ive been using Gro hair serum by Vegamour for about 6 weeks now and im very pleased. This serum is ultra lightweight with a water like consistency it doesn’t weigh down hair or make it look greasy, plus it can be applied to wet or dry hair. Since using I’ve noticed significantly less fall out, new growth on the top and temples- my hair feels more substantial with added volume & bounce. A quick and easy step worth adding to your daily routine - highly recommend!
