Causes of Grey Hair

Why does hair lose its pigment, aka melanin? Surely, there are numerous grey hair reasons other than aging. Let’s find out!

1. Genetics

Struggling with grey hair in your 20’s? Your genetic structure could be one of the premature hair greying causes. If your parents or grandparents had white hair in their early adulthood, it’s possible that you will develop white hair at an early age. While you can’t change your genetic makeup, you can certainly cover your greys with permanent hair color.

2. Loss of Melanin

Grey hair reasons often stem from low melanin production in your body. Melanin is produced every time your hair cycle begins (which lasts for several years). However, after 7–15 cycles, the melanin stops growing, causing hair to lose its pigment.

3. Stress

Chronic stress is one of the main causes of grey hair. When stressed, your body responds by releasing a hormone called norepinephrine, causing melanocytes. Under these circumstances, the melanin-producing cell crawls out of your hair follicles, turning your hair grey.

4. Vitamin Deficiency & Health Conditions

Certain grey hair reasons trace back to vitamin B-12 deficiency, thyroid disorders (hyper- or hypothyroidism), and some autoimmune diseases like vitiligo or alopecia areata. All of these health conditions may affect melanin production at the follicular level, causing white hair.

5. Smoking

Smoking and grey hair are thought to be interconnected. Smoking shrinks blood vessels, reducing blood flow to hair follicles and resulting in hair loss. Also, toxins in cigarettes can damage hair follicles, leading to white hair, making it one of the frontline premature hair greying causes.

Now that you know the reasons for silver locks, let’s learn how to slow down the causes of grey hair with simple preventive steps.
