White hair: Causes and Prevention

Introduction

Everybody knows when we get older; our hair changes colour. We have black, brown, and red hair colours at younger ages, but it changes as we age. However, nowadays, we can see that at a very young age, our youth have white or grey hair. So, in this article, I would like to discuss the causes and prevention of white colour.

Moreover, before going ahead, firstly, I defined how white colour hair occurs. 

So, our body has hair follicles and tiny sacs that line skin cells. Hair follicles have pigment cells that are called melanin. Those cells give our hair its colour. But hair follicles can lose pigment over time, resulting in white or grey hair.

1. Causes white hair at a young age

Stress

Every individual experiences stress. Some examples of Stress are exams, office, family, emotions, relationships, etc. Further, as the result of Stress, it will increase anxiety, High blood pressure, and sleep problems. However, Stress also affects hair growth and hair colour. So, Stress may be the cause of your white hair.

Genetics

Genetics is when we have things through our parents or grandparents in the mother’s womb. Moreover, we can’t change our genetics, but you can colour your hair if you don’t like them.

Autoimmune disease

When the body’s immune system attacks, its cells are called an autoimmune disease. It can attack hair and also cause loss of pigment.

Thyroid disorder

The health of our thyroid can also influence the colour of our hair. An overactive or underactive thyroid can cause our body to produce less melanin. Hormonal changes caused by a thyroid problem can also be responsible for premature white hair.

Vitamin B-12 deficiency

Vitamin B-12 plays a vital role in your body. It gives us energy and contributes to healthy hair growth and colour. For healthy red blood cell, our body needs vitamins that carries oxygen to the cell. So, a deficiency of B12 affects melanin production.

Smoking

Everybody knows that smoking injures health, but some people smoke due to bad addiction. Smoking increases the problem of the lungs and also causes heart disease. Smoking constricts blood vessels. As a result, it reduces blood flow to hair follicles, and it can cause hair loss and grey hair.
