Just as your skin ages, so too does your hair-getting thinner, limper and more unruly with time. As hair ages, we produce less Keratin because our bodies can't absorb essential minerals and vitamins as effectively. Keratin is the protein that renders hair strong and healthy. Without adequate or high-quality Keratin, strands slowly become porous, hyper-prone to breakage, and scary-skinny.
