Hair turns gray when the production of melanin, the pigment that gives hair color, decreases. The factors that lead to this are:
1. Genetics
The most important cause of premature graying is heredity. If your parents or close relatives have a tendency to gray hair at a young age, you are more likely to get it too. This is determined by genes.
2. Vitamin B12 deficiency
Vitamin B12 is essential for nerve health and maintaining the natural color of hair. Due to a deficiency of this vitamin, hair cells weaken and hair turns gray prematurely.
3. Stress
Excessive mental stress can destroy cells in the body. Studies indicate that when stress increases, the stem cells that maintain hair color are destroyed. This leads to premature graying.
4. Thyroid problems
Differences in the functioning of the thyroid gland (Hyperthyroidism/Hypothyroidism) can affect the body’s metabolism. This can reduce melanin production and cause graying and hair loss.
5. Smoking
Smokers are two and a half times more likely to develop premature gray hair than non-smokers. The toxins in tobacco constrict blood vessels and reduce blood flow to the hair roots.
6. Excessive use of chemicals
Strong hair dyes, shampoos, bleaching, etc. can destroy the melanin in the hair. Chemicals such as hydrogen peroxide contained in these can cause hair to turn gray quickly.
What can be done to prevent premature gray hair?
Food: Include eggs, milk, fish, leafy vegetables, and nuts in your diet.
Protection: Avoid excessive heat on your hair.
Gooseberry: Applying gooseberry juice or gooseberry powder to the scalp will help maintain the black color of the hair.
