As people get older, their hair often gets darker. According to IFLScience, this is due to changes in the production of melanin—the natural pigments responsible for hair, eye, and skin color. Two types of melanin are common: Eumelanin determines how dark your hair is, while pheomelanin controls how warm it is.
Changes in age, nutrition, temperature, sun exposure and various other factors can cause our bodies to change the amounts or types of hormones we make. The genes for making melanin might turn on or off over a lifetime, causing your hair color to change.
It is a dominant genetic trait, and it is found in people of all backgrounds and ethnicities. Black hair contains a large amount of eumelanin pigmentation, a type of melanin. This hair type contains a much more dense quantity of eumelanin in comparison to other hair colors, such as brown, blonde and red.
Despite the claims made online and by product marketers, it's not possible to reverse white hair if the cause is genetic. Once your hair follicles lose melanin, they can't produce it on their own.
It may also look darker than it actually is next to the gray hair. But brown hair often turns blackish as we age, this is bc the part of the hair pigment that contains 'warmth' (red or red-gold tones for brunettes) is strongly lessened in that area, so you are just left with the color part.
A variety of genetic, metabolic, nutritional, and acquired disorders result in hair color changes. When the underlying defect can be corrected, hair color usually returns to normal. The flag sign can occur as a result of nutritional insults or due to medications.
Having one particularly dark, coarse hair on your body is not unusual. Those hairs typically pop up due to changes in hormones, in response to pregnancy or menopause, or if you're genetically predisposed to having slightly higher androgen levels than average.

Graying reversal won't work for everyone
If strands are about to go gray anyway — perhaps near middle age — a stressful event might push hair cells past that threshold earlier, the study noted. Then when the stress ends and the hair is just above the threshold, it could revert back to dark.
The most common hair color in the world is black and its found in wide array of background and ethnicities. About 75 to 85% of the global population has either black hair or the deepest brown shade. People with black hair vary widely in skin tone, from pale white skin to very dark skin.
To expel the black pigment out of your hair, Ashley notes that you can either use straight-up color remover to strip the hair color (like Color Oops Hair Color Remover: $11.99) or a bleach to remove and lift. In many cases, both will be used together to get your mane back to sunnier days most effectively.
Baking Soda Paste
Baking soda can be an effective way to remove permanent hair dye naturally because of its lightening properties. Try mixing baking soda with lemon juice, which is acidic, to create a paste. Then, work the paste through your hair, allow it to sit for five minutes, and rinse thoroughly.
For the most part, having back hair is completely natural. It's up to you if you want to remove it. There are many options, from affordable, frequent treatments to more lasting and expensive ones. In some cases, having back hair may be a sign of an underlying health condition, especially for women.
The hair cycle and hair follicle structure are highly affected by various hormones. Androgens—such as testosterone (T); dihydrotestosterone (DHT); and their prohormones, dehydroepiandrosterone sulfate (DHEAS) and androstendione (A)—are the key factors in terminal hair growth.
The reason for this change is because the amount of eumelanin in your hair increases as you mature, according to some research.
Can White Hair Turn Black Again? 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.
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.
Just like a person's skin, hair goes through five specific signs of aging, says AGEbeautiful. They are: thinning hair, wiry gray hair, graying hair, dryness and dullness.
The bottom line: Several factors can change the color and texture of hair throughout your lifetime. They include stress, chemical hair treatments, heat styling, genetics, aging, medical conditions and illness. and pregnancy.
Hair color is due to a pigment called melanin, which hair follicles produce. Hair follicles are structures in the skin that make and grow hair. With aging, the follicles make less melanin, and this causes gray hair.
Chemical treatments and heat styling alike can cause changes in hair texture. Coloring, relaxing, perming, blow drying on high heat, and flat ironing can all damage hair, leaving it dry and wiry.
Trichonodosis is characterized by knotted hair on the distal portion of the hair shaft. This may be spontaneous or secondary to mechanical factors like vigorous scratching or combing the hair. Trichonodosis may be associated with abnormal scalp and body hair growth.
