COLOUR WOW Dream Filter Pre-Shampoo Mineral Remover

Washing with hard water, well water or pool water leaves behind mineral residue, and COLOUR WOW Dream Filter is a pre-shampoo mineral remover spray built to lift that residue before your regular wash. It targets calcium, magnesium, copper, iron, manganese, aluminum and chlorine, the deposits the brand links to dullness, darker-looking colour and rougher texture. Mist it on, wait, then shampoo as usual.

What the mineral-extracting blend is designed to lift

According to COLOUR WOW, this spray pulls calcium, magnesium, copper, iron, manganese, aluminum and chlorine out of the hair. The brand connects those deposits to a dull, darkened look, colour that reads off-tone, and texture that feels coarser than usual. The formulae is described as safe, non-harsh and non-stripping, and the brand calls it gentle. Because it is a pre-shampoo step, it sits ahead of your cleanser rather than standing in for one.

How to work the spray through your hair

The brand gives no measured dose per wash, so aim for an even, generous misting instead of counting sprays. Cover the hair you can see and reach, then leave the formulae on for the full three minutes the brand specifies before you shampoo. If your hair is long or dense, part it into sections so the mist gets past the top layer. There is no lather at this stage, since it is a treatment rather than a shampoo. Check the bottle label for any added guidance on use.

Using it on colour-treated hair

COLOUR WOW frames this spray around colour, stating that it removes the minerals that dull, darken and distort tone. Apply it before shampooing, let it sit for the stated three minutes, then continue with your normal wash. The brand describes the end result as brighter, shinier, silkier-looking hair.

Is this product sulfate-free?

The product data does not state whether this formulae is sulfate-free. If that matters to you, check the ingredient list on the bottle before buying.

Timing, texture and what to expect

The stated timing is the standout detail: under three minutes, which the brand calls the fastest, easiest way to remove colour-distorting minerals. You spray, wait, then shampoo as normal. Reviewers often mention how the spray applies and how hair feels afterwards, though the data offers no further detail on scent or lather. Because it is a pre-shampoo treatment rather than a shampoo, expect no lather from this step itself.

Suitable for hard, well and pool water

It is made for anyone washing with hard water, well water or pool water, and especially for colour-treated hair where the brand says minerals distort tone. If your usual shampoo leaves hair feeling dull or coarse, this adds a step before it. Pair it with your regular shampoo and conditioner as the first move in your wash routine.
