So, let's start with a bit of science, the human body has millions of hair follicles or small sacs lining the skin. The follicles generate hair and colour or pigment cells that contain melanin. Over time, hair follicles lose pigment cells, this results in grey/white hair colour.

The process of hair changing from darker colour to white or grey with age is mainly due to genetics. It can be inherited from either parent. The colour of our hair is determined by the form of hair pigment that we have.

The cells in the hair bulb produce a little bit of hydrogen peroxide, which is a metabolic byproduct, and typically there's an enzyme called catalase that breaks this down to water and oxygen. But as we age, there's declining levels of catalase, and this allows the build-up of hydrogen peroxide in the hair bulb, this damages and destroys the pigment-producing cells of our hair.

Vitamin deficiencies: Any deficiencies of vitamin B-6, B-12, biotin, vitamin D, or vitamin E can lead to premature greying.

Genetics: Premature greying is largely connected to genetics. Race and ethnicity play roles, as well. Premature greying in white people can start as early as 20 years old, while a person can be as young as 25 years old among Asians, and 30 years in African-Americans populations, according to a 2013 study:

Some medical conditions can cause premature greying including some autoimmune diseases and deficiencies in thyroid function, if you are concerned about this being a cause as you may have some other symptoms, you should speak to your GP or Pharmacist.

Stresses: There are conflicting research studies on real-life stress, such as injury, leading to premature greying.

If you are concerned about stress causing grey or white hair or stress in general, please check out my videos on reducing or managing stress and anxiety, which may be helpful to you and may be helpful to preventing prematurely greying hair:

Please also find my mental health playlist for more videos:

Smoking: A 2013 study showed that smokers are 2 ½ times more likely to start greying before 30 as non-smokers. Several studies have found a link between premature greying and smoking. It’s well-known that smoking increases the risk for lung cancer and heart disease. If you're ready to quit please find my video playlist for more support -

The long-term effects of smoking can also affect hair. Smoking constricts blood vessels, which can reduce blood flow to hair follicles and cause hair loss. Additionally, toxins in cigarettes can damage parts of your body including your hair follicles and pigmentation, causing early grey hair.

Oxidative stress: While greying is mostly genetic, oxidative stress in the body may play a part when the process happens prematurely. Oxidative stress is a complex process, but it can be simply defined as an imbalance between ‘free radicals’ and ‘antioxidants’ in your body.

Some chemical hair dyes and hair products, even shampoos, can lead to premature hair greying. Many of these products contain harmful ingredients that decrease melanin.

Hydrogen peroxide, which is in many hair dyes, is one of these harmful chemicals. Excessive use of products that can bleach hair will also eventually cause it to turn white or grey. Remember to speak to a healthcare professional when planning to use stronger hair dyes.
