This unique Pantene Pro-V hair thickening shampoo with biotin, antioxidants, and the highest concentration of Pro-V strengthens thin, dull hair, making it visibly thicker and fuller - already after the first use. The silicone-free shampoo contains three times more Pro-V than the Pantene Pro-V Repair & Care Shampoo. For best results, use in conjunction with the Pantene Pro-V Lift & Volume series: shampoo, conditioner, intensive care, and hair oil spray - suitable for daily use.
