"Biotin vs Collagen Shampoo Showdown... Tested Levels of Volume & Body in Style"

We’ve rounded up OGX Thick & Full + Biotin & Collagen Volumizing Shampoo to see how it stacks up in the battle for lasting volume. The sulfate-free formula buffs in 13 fl. oz. bottles, promising 72+ hours of lift with biotin and collagen blends for fuller hair. We appreciate the nutrient-infused surfactants that cleanse without stripping—especially for those with sensitivities. The scent is subtle, almost unnoticeable, which we like, as aromas can be distracting. The foam is rich and coats our hair evenly, leaving it feeling lightweight yet defined. After multiple washes, our hair appears visibly thicker, though we noticed the volume seems to hold better mid-shampoo than post-wash. It’s an honest contender, offering body without over-promising—perfect for mornings when we crave a quick, polished look.
