If, as they say, gray adorns a man, this phenomenon does not please women who, with the appearance of gray hair, look much older than their years.
Scientists note that lately, more and more often gray hair has been observed in young people who are not yet thirty.
What is the reason for such an early appearance of gray hair. First of all, it concerns heredity, which is passed on to a related generation, as a result of which the son or daughter grow gray at the same age as their parents.
Early graying may indicate some diseases, for example, disruption of the digestive tract, thyroid gland, and also, with poor blood circulation.
Regardless of the age at which a person is, if he often encounters stressful situations or has a depressive condition for a long time, it can affect the appearance of gray hair. And, just like some habits, for example, smoking, coffee, which is drunk in large quantities, and even salt, if it is abused.Source: www.goodshelp.com
