Ideal for thinning hair types, the Fortifying Leave-in Treatment helps to minimise the risk of hair breakage as the final step of the Aveda Invati Ultra Advanced four-step system. The leave-in conditioner works to reduce tangles and knots with its softening formula, defending lengths against damage and split ends. The treatment visibly strengthens the look of strands, while enhancing manageability and reducing the look of flyaways. Hair is enveloped in the refreshing Aveda’s Pure-Fume™Aroma, infused with lavender, vanilla and sandalwood. Vegan.
