Lanza Healing Volume Thickening Shampoo is a professional hair care formulation designed to add body and fullness to fine, limp, or thinning hair. This 1000 ml bottle provides an economical option for regular use. The shampoo works by gently cleansing while adding texture and lift at the roots, creating the appearance of thicker, more voluminous hair. It contains keratin proteins and amino acids that help strengthen hair strands from within, reducing breakage and improving overall hair resilience. The formula is sulfate-free and color-safe, making it suitable for color-treated or chemically processed hair. It features a lightweight consistency that rinses clean without leaving residue or weighing hair down. The pH-balanced formulation helps maintain the natural acidity of the scalp and hair cuticle. The shampoo produces a rich, creamy lather that effectively removes dirt, oil, and product buildup while being gentle enough for daily use. It leaves hair feeling clean, refreshed, and manageable with improved body and bounce. The subtle, fresh scent is not overpowering and dissipates quickly after rinsing. This professional-grade shampoo is developed for those seeking to enhance natural volume and thickness without compromising hair health or integrity.
