OGX Extra Volume Biotin Collagen Shampoo is designed to enhance the look of fuller, thicker hair while gently cleansing from root to tip. Infused with biotin and collagen, this formula helps improve the appearance of volume and body, making hair feel more lifted and manageable. Its lightweight yet nourishing blend works well for fine or flat hair types seeking added texture without weighing strands down. The shampoo produces a rich lather that effectively removes buildup while maintaining a soft, smooth finish. Suitable for everyday use, it leaves hair looking refreshed, with a healthy shine and a more voluminous appearance that complements different hair styling routines.
