OGX Thick & Full Biotin & Collagen Shampoo is formulated to help give hair a fuller-looking appearance while gently cleansing away dirt, excess oil, and product buildup. Enriched with biotin and collagen, it helps improve the look of volume and body, leaving hair feeling soft, smooth, and refreshed after every wash. Suitable for daily hair care, the rich lather helps maintain healthy-looking strands without weighing them down. It works well for fine or flat hair, helping enhance texture and making hair easier to manage. The formula supports a clean, fresh feeling while promoting hair that looks thicker, shinier, and more vibrant. For best results, use regularly as part of your hair care routine with a matching conditioner.
