Basically, dandruff has two causes: an overly dry scalp with small flakes flaking off, or malassezia yeast, the overgrowth of which can cause inflammation and thus dandruff. It is difficult for yourself to know why this is happening to you, which is why our shampoo combats both causes. The complex of amino acids and aloe vera helps to moisturize the scalp, herbal extracts and cetylpyridinium chloride in turn show the yeast to the correct limits. Moreover, it is also 99% natural. The percentage has escaped us through preservative, but otherwise it wouldn't last long enough in your bathroom. Of course you only fight with a magnifying glass, but it also beautifully cares for your hair - it naturally nourishes, thanks to the tissue protein, sericin gives an almost silky shine and is of course soft but thoroughly washed. What more could you want from shampoo? Made in the Czech Republic. Like all Beviro products.
