Symptoms of ageing most of the time includes grey strands of hair. however, gray hair may not always suggest that you're getting older. Sometimes people tend to start showing grey hair at a younger period of their life which is known as premature greying, It could be attributed to various factors including genetics.
Dr. Sermed Mezher, MBChB (Hons) MRes, a Locum General Practitioner from London took his Instagram to speak about this topic and shared his insights regarding the causes and how this condition can be avoided.
In his video, Dr.S ermed expressed that most people develop grey hair by the mid-30s, but it can occur prematurely and this is mostly due to genetics. He added some other causes that are preventable and can be reversed. For example, excessive accumulation of oxidative stress can damage the hair follicle which is most commonly due to sunlight exposure this can be easily avoided by wearing a hat or any protection while you go outside. Deficiencies of Vitamin D and Vitamin B12, Copper and thyroid conditions can also cause premature greying.
Ages when greying is considered premature (2)
Whites: before age 20
Asians: before age 25
Blacks: before age 30
Reversible causes of Premature greying of hair:
Nutrient Deficiencies: A lack of vitamin B12 or B9, vitamin D, iron, copper, or biotin can contribute to early greying.
This can be prevented by having a balanced diet rich in fruits, vegetables, and whole grains or taking supplements under a doctor's guidance.
Medical Conditions: Certain autoimmune diseases or thyroid problems can affect pigment cells.
Treating the underlying condition might bring back hair color.
Oxidative stress: In this condition antioxidants are not enough to counteract the damaging effects of free radicals which are the unstable molecules that damage cells, contributing to aging and disease.
Stress: Emerging research suggests stress may affect pigment production in hair follicles.
By managing stress through exercise, relaxation techniques, or addressing its source, some reversal could be possible, particularly in younger individuals.
Smoking: Smoking has also been shown to increase the risk of premature greying.
Chemical hair dyes and hair products: Chemical hair dyes and hair products, even shampoos, can lead to premature hair graying. Many of these products contain harmful ingredients like Hydrogen peroxide that decrease melanin. (1,2)
Protein malnutrition can also be one of the causes and it is reversible where in once the diet is sufficed the hair goes back to regular hair color.

Eat a healthy balanced diet and address any deficiency that you may come across. For example, Seafood, eggs, and meats are good sources of vitamin B12. Milk, salmon, and cheese are sources of vitamin D.
Eat more anti oxidants like fruits and vegetables, green tea, olive oil and fish.
Wear a hat or any protection over your hair while getting exposed to sunlight.
Natural remedies like curry leaves and bhringaraj can be used to make the hair darker .(1)
It's important to note that reversing greying isn't guaranteed in these cases. However, addressing these potential causes can promote overall hair health and potentially slow down the process. Consulting a doctor can help identify any underlying issues and recommend the best course of action.
