Canities, or hair greying, is a biological ageing process that affects people of all races and genders. Graying occurs at different ages depending on race and ethnicity. But if the greying of hair develops before the age of 20 years in Whites, 25 years in Asians, and 30 years in Africans then it is considered as premature greying of hair.
What causes white hair?
- Premature greying can be caused by vitamin B-6, B-12, biotin, vitamin D, or vitamin E deficiency.
- Genetics can also play a role in premature greying of a person’s hair.
- Chemical hair colours and hair products, including shampoos, can cause premature greying of the hair.
- Many of these products contain chemicals that reduce melanin production.
- One more dangerous ingredient that can cause premature greying of hair is hydrogen peroxide, which is included in many hair colours.
- Excessive use of bleaching agents will also ultimately cause hair to turn white.
- Stress produces body imbalances, which leads to premature greying of hair.
- A person’s risk of greying early may be increased by certain medical disorders, such as autoimmune diseases.
- Smoking.
Treatments and Medications
The doctor will prescribe medications after analysing to the underlying problems such as thyroid issues or alopecia areata or any other disorders in the body that may be causing the greying of hair. Doctors may prescribe topical shampoos or hair treatments to help with hair loss control in some circumstances. Do not self-medicate; always take medications as advised by your doctor.
