A detoxifying shampoo that removes product and mineral build-up from hair and scalp without stripping natural oils β safe for colour-treated hair, and the ideal pre-wash before any Kevin Murphy regimen.
Maxi Wash is a one-product job with a specific purpose: reset. If your hair has been feeling heavy, dull, or like your regular shampoo and conditioner are not performing the way they should, build-up is usually the reason. Product accumulates on the hair shaft. Minerals from tap water bind to the cuticle. Both interfere with how everything else you apply β colour, treatments, styling products β actually works. Maxi Wash clears the slate.
What makes it worth mentioning specifically is what it does not do. Unlike most clarifying shampoos, it does not strip colour or deplete the hair's natural oils. The AHAs from fruit extracts do the heavy lifting on debris, while Witch Hazel tightens the cuticle and Thyme and Rosemary antioxidants actively protect colour retention during the cleanse. It deep-cleans without the trade-off most clarifying shampoos make.
As a White Haven Kevin Murphy salon, Maxi Wash earns a place in our recommendations because of how clearly it improves the performance of everything that follows it. The brand designed it explicitly as a pre-wash β not just as a standalone clarifying option. Clients who use it before their regular routine find that their shampoo lathers better, their conditioner absorbs more effectively, and their colour holds more evenly. That is not a coincidence; that is what clean hair does.
Use it before your regular shampoo, not instead of it. Apply, massage gently (do not scrub β the AHAs need contact time, not friction), leave for one minute, rinse, then follow your usual Kevin Murphy wash and condition routine. Everything you apply after will perform noticeably better on freshly clarified hair. Once a week is the standard frequency, or any time your hair feels heavy or your products feel like they have stopped working.
If your scalp is sensitive or reactive, introduce it slowly β once a fortnight before moving to weekly. If your hair is very dry or severely damaged, prioritise repair with Re.Store or Repair Me Wash before adding a clarifying step. Maxi Wash is designed for all hair types and is safe for colour-treated hair, but dry or compromised hair benefits more from getting its structure repaired before focusing on build-up removal.
