There are both external and internal factors that affect the quality and well-being of your hair. For example, using the right shampoo and conditioner, not washing your hair too often, avoiding putting your hair in too tight hair bands are well-known external factors that affect your hair quality. What you can do is boost the hair from the inside, with the vitamins and minerals that provide the best conditions for healthy hair. Zinc and biotin strengthen while folic acid, iodine and B vitamins provide nutrition. The ingredients are carefully adapted to strengthen your hair in a natural way. We recommend carrying out at least one treatment (30 days / 1 can).
