2. Smoking
Smoking causes chemical changes to your body that damage the melanin-producing cells in your hair, which make your hair grow gray at an early age.
3. Constant, long-term stress may contribute to gray hair
High stress levels may damage the chemicals that produce melanin in your hair. Gray hair occur due to the loss of melanin.
- If you’re feeling stressed and you’d like to lower your stress levels, try exercising daily, practicing meditation, and getting at least 8 hours of sleep every night.
- Some studies suggest that oxidative stress, or breathing in toxins like pollutants and heavy metals over a long period of time, may also contribute to gray hair
Certain autoimmune diseases can cause younger people to develop gray hairs. Examples of autoimmune diseases are alopecia and vitiligo.
5. Genetics
If you start developing gray hairs at an early age, it is most likely that your parents also experienced it early.
