Depression produces vasoconstricicón phenomenon, ie a decrease in the caliber of the blood vessel by contraction of muscle fibers.
At that moment everything seems to become slower, the blood does not circulate at a good pace and not the lymphatic system, eyes swollen and dull complexion.
But not everything happens in the skin, hair also becomes a victim. Vasoconstriction takes from the hair bulbs proper vascularization, causing the hair loses shine and vigor.
So depressed in situations of crisis or in stages, pay special attention to the hair, applying nourishing creams and washed with warm water, massaging the scalp with the fingertips and gently (never with nails and with violence).
