I have been using PhytoArgent Whitening Shampo for two weeks now and the whitening process is gradual. My grey/white beard is becoming more evenly white which is what I wanted and also looks brighter. The purple colour of the product is a little off-putting though, and it does leave your hands tainted a slight blue/purple colour, but this does come off with a good scrub and, in hindsight, applying with gloves is a better idea. All in all though - a good and useful product

Used this product several times now and it has significantly enhanced my hair. Naturally before the grey I was mid brown, so as the grey came it got increasingly yellowy in tone. With PhytoArgent its now more white and steel grey. Looks more distinguished and well groomed. I feel more comfortable & confident being grey now. I recommend it, especially if you feel you need control over your hair again. It is a much better option than Dyeing your hair.

This is working on my grey hair after only two weeks, leaving it lighter with a lovely soft shine, using as instructed it is going to prove very good value for money!
