Kevin Murphy MAXI.WASH Detoxifying & Clarifying Shampoo (33.8 oz / 1 Liter) - RARE Professional Backbar Size

Product Description

Purify your scalp, slough away stubborn product buildup, and reset your hair with AHA fruit acid clarifying power—now in the rare 1-Liter professional backbar size.

Give your hair and scalp a clean slate. Kevin Murphy MAXI.WASH is a powerful yet gentle detoxifying shampoo formulated with Alpha Hydroxy Acids (AHAs) to break down excess styling product, hard water minerals, pollutants, and unwanted chemicals without stripping essential moisture or natural oils. Offered in the massive 33.8 oz (1 Liter) professional backbar bottle, this hard-to-find salon size holds 4 times the volume of standard retail bottles, offering superior cost-per-ounce value for your weekly clarifying routine.

Powered by a soothing essential oil blend of Tea Tree Oil, Witch Hazel Extract, and Thyme, this purifying wash cleanses deep into the scalp pores to calm irritation and stimulate sluggish hair follicles. Infused with Grapefruit Extract and Rosemary, it restores natural radiance, tightens the hair cuticle layer, and perfectly prepares your strands to absorb deep conditioners and color treatments.
