Instantly get the look and feel of more hair. 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 your hair, reducing hair loss due to breakage (*vs. a basic shampoo). Our John Frieda ULTRAfiller+ technology strengthens, adding manageability to fine, fragile hair while increasing overall hair thickness and plumpness. It accomplishes this by aligning and creating spaces between hair fibers, resulting in hair that looks and feels thicker. Give fine, flat hair an instant thickening boost with this silicone-free and vegan friendly volumizing shampoo. To use, work our volumizing shampoo gently through wet hair, lather, and rinse well. Try the full ULTRAfiller+ thickening line, which is a 3-step process for thicker, fuller hair. Together, all three products complement each other for the best results. Step 1 is to cleanse with our thickening shampoo that visually plumps in only one use. Step 2 is to strengthen as you condition, helping to align the hair, creating thickness with our ULTRAfiller+ conditioner. Step 3 is to thicken with our thickening spray, which plumps your overall thickness and provides heat protection for fragile hair. You are one thickening shampoo away from thicker, bouncier, more resilient hair!
