It is ideal for hair with dandruff, which typically affects men and is due to various factors, including stress and poor diet. The main ingredient around which the composition of this product is developed is spirulina, primarily known as a nutritional supplement, but great also for cosmetics. Spirulina, and seaweeds in general, are rich in vitamins (A in particular) and minerals (among which zinc and selenium) that help restoring skin hydrolipidic balance and controlling sebaceous glands activity; for this reason they prove particularly effective in treating dandruff.
