Hair going grey, silver, or white is a natural part of aging. Each hair is made up of two parts- a shaft, the coloured part, and root, the bottom part, which keeps hair attached to the scalp. The root of each strand of hair is surrounded by the hair follicle. Each hair follicle contains a certain number of pigment (melanin) cells. They give the growing hair its colour- black, brown or blonde.
- AGE – When we get older, the pigment cells in our hair follicles slowly wither. This leads to fewer pigment cells in the hair follicle. The result- hair strands no longer contain as much melanin as before. The hair now wears a more transparent colour – like grey, silver or white as it grows. Eventually, the hair will look completely grey.
People can get grey hair at any age. Some people ‘go’ grey at a very young age, even in their teens, whereas others may go ‘grey’ haired’ in their 30s and 40s. In some instances, it may take more than 10-12 years years for all of a person’s hair to ‘go’ grey.
Greying spreads in the following sequel- the sideburns, beard, chest and the scalp. How early one gets affected with grey hair is determined by your genes. This is one of the reasons why most of us start having grey hair around the same age that our parents or grandparents first did.
- DIET:-Lack of vitamin B 12 (cobalamin) and folic acid can trigger grey hair, besides anemia. In a new study, researchers from Sweden report that when participants suffering from vitiligo (white patches) increased their consumption of vitamin B 12 and folic acid, through their diets and oral supplements, there was re-pigmentation of grey hair in 64 percent of the patients, with six individuals experiencing total re-pigmentation.
- SMOKING:-Smoking can cause your hair to prematurely grey. A study in the UK found that smokers were up to four times more likely to have grey hair than their non-smoking counterparts.
- DENTAL WHITENING PRODUCTS:-The ‘whitener’ smile of your teeth-whitening toothpaste is also said to blot your hair colour. A study has shown that even a tiny dose of hydrogen peroxide, found in teeth-whiteners, can ’initiate’ melanocyte ‘death’ a likely trigger for colour change in your hair.
- POLLUTION:-Pollutants, chemicals, ultraviolet (UV) light and free radicals by products of chemical processes, responsible for aging and tissue damage can impinge on melanin production, while impacting your hair’s natural pigmentation, triggering grey hair.
- GENTICS:-Research shows that our genetics is behind graying hair. Our inheritance determines not only our colour, but also when hair graying begins.
- HAIR CARE PRODUCTS:-Strong chemical hair bleaches, dyes, conditioners and shampoos can contribute to graying of hair sooner than later.
- THYROID:-Thyroid disorders can lead to grey hair, or diffuse grey hair at young age.
- VITILIGO:-This is a condition in which hair loses pigmentation in patches due to a decrease in melanin production. As a result, the hair follicles that grow after melanin loss have no colour hence, the grey appearance only in those patches affected by vitiligo.
- STRESS:-Emotional stress prompts a ‘bad’ chemical rush in our body, leading to melanin ‘demise’ Result grey hair. Work or personal stress or, more precisely, cellular stress can also likewise, turn your hair grey.
Grey hair, caused as a result of conditions such as thyroid disorders, vitamin B 12 deficiency and vitiligo in younger individuals can be treated effectively with appropriate homeopathic treatment.
