If the hair becomes thinner or falls out, this can be a sign of deficiencies or enormous stress. Thinning hair can also be caused by genetic factors or the natural aging process. Due to the undersupply of nutrients to the hair roots, the hair appears weak, greasy and the scalp shines through visibly. With preparations or a change in diet you can strengthen the hair roots again and help the hair to regain its vitality. However, a visit to a doctor is recommended in any case to determine the exact causes. Read more about hair loss or visit our beauty guide for more information.
