Today marks the second day of usage, and while I haven’t seen a change in hair color yet, I'm optimistic. Once you’ve reached your preferred level of grey reduction, you can reduce the frequency of use to maintain your desired color.

Before using this product, you must perform a preliminary 48-hour skin allergy test according to accompany directions.

Control GX Light Shades Shampoo has a breakthrough triple-patented formula that provides subtle, gradual results so you'll always have a very look. It is important to perform a patch test before full application to check for any allergic reactions or scalp sensitivity. Choose from a selection of shades that complement your natural hair color, allowing for a seamless and blended effect.

Remember to perform the 48-hour skin allergy patch (alert) test before each use even if you have previously used this or other hair colouring products. We have incorporated a unique, patented grey-reducing complex that will gradually reduce the amount of grey in your hair every time you shampoo. When you are done, don’t forget to clean the bath, and I mean you have to use good old cleaning products because you can find some nasty stains on your bath!

Just for Men Control GX Grey Reducing Light shade Shampoo reduces grey a little bit with each shampoo for subtle, gradual results. Some men, depending on their type of hair and preference, can reach full coverage with frequent use, but overall Control GX® is designed to be subtle — gradually blending away a little grey with each shampoo.
