However, the genetic aetiology of grey hair is still unknown.
The chromatin of the hair depends on the presence and amount of melanin. Melanin is synthesised in the matrix cells of the hair follicle, in specialised organelles called melanosomes.
What is Premature Greying?
Going grey is just a natural part of the ageing process. Every hair follicle contains pigment cells, which produce melanin — the pigment that gives hair its natural colour. Over time, those pigment cells die, leaving behind strands of grey, white or transparent hair.
Premature greying of hair (PGH) is called greying of hair before the age of 20 or 30. Greying of hair is also said as achromotrichia or canities as well. Premature greying causes severe affection on an individual.
‘Canities’ is a term used to describe greying of hair, which is one of the most visible and frequent signs of ageing. The clinical presentation can vary from premature canities (that develop at less than 20% years of age), salt and pepper canities (with gradual appearance of grey hair), or premature canities that occur genetically even at an earlier age.
Premature greying of hair (PGH) is defined as greying of hair before the age of 20 in Caucasians and before 30 years in Africans and Asians. The actual age at which greying appears,: however, is largely dependent on the genetic and environmental factors. Premature greying can be an important determinant for the diagnosis of a variety of diseases ranging from endocrinopathies to vitiligo.
While vitiligo and other autoimmune diseases have long been investigated for their association with PGH, research in recent years has also emphasised on its link with a wide spectrum of other disorders such as thyroid disease.
Moreover, diabetes mellitus, malnutrition, nutritional deficiency, parasitic infestations, lead poisoning, pernicious anaemia, Addison’s disease, psoriasis, alopecia areata, systemic lupus erythematosus and tumours. There is also poor evidence of PGH being linked to Down’s syndrome, Turner’s syndrome, Wilson’s disease and Klinefelter’s syndrome.
Premature greying, which is uncommon in those under 30, is characterised by more than 50% of hairs turning grey. There are many factors that may cause premature greying., including genetics and stress.
Premature greying causes an increase of low self esteem, and also gives rise to a lot of adjustment in social or cultural gathering. The relation of greying is directly related to your age and can also come in any of the individuals despite their age and gender.

Passing On With Genetic Factor
Genetics leads to the study of heredity and genes of Ancestors. It states, some of the other factors in our body are similar to our ancestors which comes into DNA Sequence. Gene have free factors such as Single gene, chromosomal and multifactor. Genetic factors can also lead to premature greying. If there was a history with family then yes there are chances of premature greying.
Deficiency in Nutrition
Most of the cases of premature greying of hair are due to a deficiency of Vitamin B12 and vitamin B3. A peculiar reason for hair greying is Folic Acid deficiency. Deficiency of Folic Acid in children leads to premature greying. Grey hair at an early age (below 20 years) is seen to be hereditary in most cases.
Sometimes, low levels of thyroid hormone can lead to premature greying of hair. Causes of premature greying of hair are both internal and external. Internal causes include infections, disorders and syndromes. External factors mainly include poor diet and lifestyle habits.
Vitiligo, neurofibromatosis and hypothyroidism are some diseases that can affect the colour of your hair, often leading it to grey prematurely. Get to know more about the causes of premature greying here.
Intake of Medicine
Some medications, like chloroquine and mephenesin which are used to treat malaria may cause your hair to turn grey. Topical applications like dithranol, chrysarobin and resorcinol used for the treatment of psoriasis are also known to cause premature greying. If you think any of these medications might be causing your hair to turn grey, talk to your doctor about adjusting or replacing them.
When there is an issue in the thyroid gland, it can likewise lead to premature greying.

If there are vitamin deficiencies then he/she should consume a lot of food containing more vitamins. Such as Eggs, Seafood, Meat as they give vitamin B12 which is essential when you have grey hair and salmon, cheese and milk are the best foods for Vitamin D deficiency. Always eat antioxidant rich food such as fresh vegetables and fruits, olive oil, green tea, etc.

⦁ In addition to this, the trichologist might examine other parts of your body as well. You will also be asked to answer a few questions regarding any medication or treatment that you might have undergone in the past. If required, a sample of your blood can also be taken for further examination.
⦁ Patients will begin to exhibit signs of premature greying from their mid-20s on. This can sometimes be attributed to other expressions of autoimmune manifestation, including vitiligo.
⦁ Diagnosis completely depends on an individual’s genetics. So, firstly identity the reason behind the white hair
⦁ Amino acids and vitamins B complex internally, along with sun exposure. Iron supplements if needed.

The colour changes are usually seen after 2-3 months and white hair may start appearing.

Premature Canities- A Treatment to Premature Greying
Greying before the age of 40 is a significant reason for low self-esteem and can interfere with the adjustment to a changing society and culture. The beginning and progress of premature canities or greying correlate closely with the progression of chronological age and can be seen in different levels in everyone eventually, regardless of gender or race.
The premature canities may manifest due to an autosomal dominance issue or in conjunction with other disorders of premature ageing or autoimmune. It must be distinguished from the various genetic hypomelanotic hair diseases. The reduction in melanogenic ally active melanocytes within the bulb that produces hair of hair follicles that are grey, which results in loss of pigmentation, is the main cause of greying.
The melanosomal transfer defect to cortical keratinocytes as well as melanin incontinence resulting from melanocyte degeneration is believed to be responsible for this. The white hue of the calves is believed to be an optical phenomenon; the reflection of light reveals the natural pale yellow hue of hair Keratin.
A full range of colours from normal to white may be observed on both individual hair and between hair and hair, and the admixture of pigmented as well as colored hair is thought to create a grey-looking appearance. Hair greying is typically permanent and progressive; however, there have been stories of spontaneous repigmentation occurring in grey hair.
Treatment for hair that is prematurely greying is done to stop and reverse the process of greying. Different treatment options for premature greying of hair are:
Treatment and Medication: Your physician may prescribe gels, creams or shampoo, or oil for topical application to your scalp and hair.

The cost of treatment for grey hair may differ from city to city and condition to condition.
Diet: A nutritious diet that has balanced amounts of all the nutrients is vital for completing every hair-care treatment. Protein-rich food items and foods high in vitamins like Vitamin D-rich foods, minerals, and iron do help in treating premature greying of hair but also aid in preventing the process from progressing to a greater degree.
Lifestyle Modifications: Healthy lifestyle choices such as abstaining from drinking, quitting smoking, as well as managing your stress levels are essential components of treating premature greying of hair. Avoid harsh treatments such as hair styling products that contain chemicals and the application of heat to your hair.
