Infused with biotin and hyaluronic acid, this thickening shampoo visibly plumps, leaving you with thicker, fuller and stronger hair in only one use! Our hair thickening shampoo plumps the overall thickness of your hair by 200%* and strengthens, reducing hair loss due to breakage (*vs. a basic shampoo). Our technology adds manageability to fine, fragile hair while increasing overall thickness and plumpness. It aligns and creates spaces between hair fibers, making your hair look and feel thicker.
