Over time, your hair can change – and not all of those changes are welcome ones. From thinning to stalled growth to hair loss, there are plenty of reasons you might want to increase your hair’s thickness and fullness.

If you’re looking to get your hair growing once again, you need a shampoo that’s designed to stimulate growth. And the right shampoo could restore full, thick hair to your head.

Nearly any big life change can cause changes in your hair growth. New York City dermatologist Dendy Engelman, M.D.¹ explains that while genetics and hormones play a role, age can also cause thinning, breakage, and hair loss. And aging can significantly reduce the hair on your head.

To achieve healthy hair growth and the fuller, thicker hair you want, try one of the following shampoos. Each one is specially formulated to strengthen hair, increase thickness, and help you avoid hair loss.
