Most people notice their first gray hairs in their 30s and have a significant amount by their 50s. But it’s not totally unusual for that process to start in your 20s with the odd gray hair or two. Whether or not you get those “premature” grays depends almost entirely on your genetics.
Though doctors and scientists have not been able to find out the exact cause yet, here are a few conditions which can lead to premature greying of hair.
1. Genetic factor
If a person has a history of premature greying in their family, then they have a chance of getting grey hair earlier in life.
2. Medications
Certain medications like chloroquine (used for malaria, mephenesin a muscle relaxant, phenylthiourea used in DNA testing, triparanol used to reduce cholesterol, and dixyrazine used to treat various psychiatric disorders are known to cause grey hair.
3. Stress- Stress is something that can affect anyone at any time. The kind of stress you are going through will determine how your body feels and looks, as well as what kind of moods or behaviours arise in yourself when under this type of discomfort- whether it’s emotional, physical or both.
4. Smoking
The connection between smoking and premature gray hairs isn’t totally understood, but it has definitely been observed in studies for decades now. More recent research confirms that having gray hairs before the age of 30 is more common among smokers than the rest of the population.
5. Nutritional Deficiencies
A few nutritional deficiencies have been linked to premature grays. For instance, a vitamin B12 deficiency can cause hair loss and encourage gray hairs to form. This vitamin is found in eggs, meat, poultry, and dairy products. So, if you’re a vegan or vegetarian or otherwise limiting your protein intake you could be at a higher risk for B12 deficiency. Make sure to check in with your doctor if you think that’s the case.
