Aveda Invati Advanced Exfoliating Shampoo 33.8-fl oz/1L Rich. Retail $152

The first step in the routine is this purifying hair follicle shampoo for thinning hair. It gently exfoliates with wintergreen-derived salicylic acid, removing oil and environmental residues that can clog pores. Gentle and non-irritating to the scalp, the formula creates a light, frothy lather and rinses clean. It leaves hair shiny and, when paired with our Light Thickening Conditioner, helps thicken strands. Suitable for: • Fine to medium thinning hair types • Normal to oily scalp Aroma: • Soothing Pure-Fume™ aroma with lavender, clary sage, Australian sandalwood, vanilla, and other pure plant and flower essences
