Waardenburg syndrome is a group of conditions passed down through families. The syndrome involves deafness and pale skin, hair, and eye color.
A new study shows that stress really can give you gray hair. Researchers found that the body's fight-or-flight response plays a key role in turning hair gray. Your hair color is determined by pigment-producing cells called melanocytes.
POSSIBLE ETIOPATHOGENESIS OF GRAYING
Reversible hypopigmentation of the hair can be seen in nutritional deficiencies protein-energy malnutrition and diseases of chronic loss of protein. Copper and iron deficiency also can cause graying of hair.
Typically, white people start going gray in their mid-30s, Asians in their late 30s, and Blacks in their mid-40s. Half of all people have a significant amount of gray hair by the time they turn 50.
The vast majority of people with gray hair have age-related graying. However, sometimes graying hair indicates an illness, especially if it occurs at a particularly young age. Health problems that may be heralded by gray hair include: vitamin B12 deficiency.
Stress can cause hair to gray prematurely by affecting the stem cells that are responsible for regenerating hair pigment.
Substantially More Grey Hair
om weak or dead hair follicles, lack of a proper sleep cycle can also cause your hair to grey faster than it would normally. That's because the hormonal imbalance that follows when you're not sleeping properly, makes your body produce less eumelanin, the pigment that makes your hair black.
People who suffer from acidity, liver problems will also experience premature greying due to unbalanced body chemistry. Those white strands on your head in your 20s are also the result of leading an unhealthy lifestyle.
Grey hairs at the front of your head have also been associated with gastrointestinal problems such as stomach acid reflux. Luckily, such issues can usually be fixed or altered with changes to your diet, so make sure to eat slowly and increase your dose of whole grains, root vegetables, unsaturated fats, and ginger!
Gray hair comes down to melanin, or rather the lack of melanin. Melanin is the pigment that gives hair its color. Gray hair has reduced melanin, while white hair completely lacks it. This occurs because of a gradual decline in the number of stem cells that mature to become melanin-producing cells.
White hair could be a sign of an underlying health concern—a symptom of an autoimmune disease, thyroid levels, allergies, or a side effect of medical treatment. It can also be a sign of hormonal imbalance.
Premature graying may be reversed with vitamin B12 supplementation only if vitamin B12 deficiency is the cause. If you are graying due to other factors, such as genetics, zinc deficiency, and medications, your gray hair cannot be reversed.
Iron deficiency can also lead to grey hair. Iron is a vital mineral that helps create haemoglobin – the substance found in RBCs. Lacking an adequate amount of iron means lesser blood cells, which leads to insufficient oxygen supply to your scalp. Naturally, this causes grey hair at a young age.
Genetic or age related greying of hair cannot be reversed. However, greying related to diet, pollution, bleaching and stress can be slowed down with a balanced diet and a good hair care regimen.
The one word answer to this question is “no”! Plucking white hair does not give you more white hair. Each of your hair strands grows out of a single hair follicle. So if you pull out the white hair only one hair can grow back in its place and possibly it will be white too.
Thyroid disorders like hyperthyroidism or hypothyroidism can cause hormonal imbalances in the body, which may result in premature greying of hair. The health of your thyroid gland can determine the colour of your hair strands. Abnormal levels of thyroid hormones produced by the gland can produce less melanin.
Either an underactive thyroid (a medical condition called hypothyroidism), or an overactive thyroid (hyperthyroidism), can result in hair loss because each condition causes a hormonal imbalance.
B complex vitamins such as B12, Biotin, and B6 are important for strength and colour of hair. Deficiencies of any of these nutrients are known to promote hair greying. B complex supplements are very useful in preventing greying.
