Ever feel like your hair just isn't responding the way it should? Like it's a bit dull, heavy or flat no matter what you do? Chances are it's build-up — and your regular shampoo isn't designed to deal with it. Crystal Clearifying Weekly Prepping Power Shampoo is your weekly reset. It gently but powerfully draws out the hard water minerals, chlorine, chemical residue and styling product build-up that accumulates in your hair over time. Use it once a week and you'll notice the difference straight away — lighter, shinier, bouncier hair that actually responds to your other products again.

Most shampoos clean the surface. Crystal Clearifying goes deeper.

Using a unique dual chelating formula, it actively bonds with metallic ions and mineral deposits sitting inside the hair shaft — drawing out hard water calcium, chlorine from swimming pools, chemical residue from colour treatments, and build-up from styling products like hairspray, wax, gel and mousse.

At the same time, Glycosaminoglycans restore hydration deep within the hair, rebalancing and replenishing as it cleanses. Rather than leaving your hair stripped and dry, this one leaves it smooth, moisturised and full of natural shine.

pH balanced at 7.5. Gentle enough for weekly use on all hair types.

Benefits:

  • Removes hard water mineral deposits and calcium build-up
  • Eliminates chlorine build-up from swimming pools
  • Clears residue from hair colour and chemical treatments
  • Removes styling product build-up — hairspray, wax, gel and mousse
  • Restores moisture and rebalances the hair's natural lipids
  • Improves elasticity for better bounce and movement
  • Leaves hair smooth, lightweight and brilliantly shiny
  • pH balanced at 7.5 — gentle enough for weekly use
  1. Wet your hair thoroughly with warm water
  2. Apply and massage firmly through the hair from roots to ends, working up a good lather
  3. Rinse out thoroughly
  4. Follow with your regular shampoo and conditioner as normal
  5. Style as desired

Tip: For heavy mineral or product build-up, apply a second time before rinsing for maximum results.

Dual Chelating Complex (Tetrasodium EDTA & Trisodium HEDTA)
The clever bit. These two ingredients bond with metallic ions and mineral deposits in the hair, drawing out hard water calcium, chlorine and chemical residue that regular shampoos simply can't touch.
Glycosaminoglycans
A natural moisture-binding complex that restores hydration deep within the hair shaft — rebalancing and replenishing as it cleanses, so hair feels soft and smooth rather than stripped.
Sodium C14-16 Olefin Sulfonate & Sodium Laureth Sulfate
The cleansing agents that create a rich lather to lift away oil, dirt, minerals and product residue.
Cocamidopropyl Betaine
Derived from coconut oil, this gentle conditioner softens the cleansing action so hair feels smooth and manageable after washing.
Menthol
Gives a fresh, cooling sensation on the scalp and helps invigorate the hair and follicles during cleansing.
Phosphoric Acid
Keeps the formula pH balanced at 7.5 — effective but gentle on the hair's natural structure.

I’ve been using this product for many years, recommended by hairdresser. I use it about once a fortnight to remove hair products (styling mousse and hairspray). I leave it on for about 15 mins to do its job, it leaves my hair clean and bouncy. It then styles easily.

This is the best shampoo I have found for dandruff, build up of conditioner and removing of chlorine

Ms O. · 6 years ago

This product was recommended by my hairdresser as essential for removing chemicals from the hair after swimming in a chlorinated pool. It is very concentrated and a small amount produces a rich lather. It also has a lovely fresh peppermint fragrance. I now use it once a week to really give a deep clean to my hair, alternating with a moisturizing shampoo that I also use once a week, i.e., I wash my hair twice a week on average.

Miss L. · 6 years ago

It works really well to remove build up of previous products and leaves the scalp feeling properly cleaned and fresh
