What it is: A nourishing shampoo that gently exfoliates with wintergreen-derived salicylic acid, removing oil and environmental residues that can clog pores. What it does: The shampoo (as well as the rest of the invati ultra advanced 4-step system, sold separately) can help reduce hair loss and thinning hair. The first step in your routine is a purifying hair follicle shampoo. Gentle and nonirritating to the scalp, the formula creates a rich, creamy lather for a clean yet nourished feeling. Hair is left shiny, softened and smoothed. How to use: Massage into wet hair and scalp. Rinse. Use as part of the invati ultra advanced 4-step system (sold separately).
