3. Unite Volume Shampoo and Conditioner

When my hairstylist used the Unite Volume Shampoo and Conditioner on my hair several years ago, I liked the results so much that I purchased it right away. Both of these products deliver thicker looking hair, without sulfates, parabens, gluten, sodium chloride, DEA, and MEA. They are also vegan if that is important to you. One thing you might really like about this shampoo and conditioner is the slight coconut scent. It makes you feel like you are on summer vacation every time you use them. Also, both products last a long time, which means you get more for your money.
