Environmental Factors: Certain factors like exposure to the sun can cause black hair to lighten, taking on a red, copper, or even blonde hue. Natural oils produced by the scalp may also interact with the sun's ultraviolet radiation to alter hair color over time.
Underlying Pigments: Black hair has a lot of eumelanin, which is dark and can lead to warm undertones (like orange or brassy tones) when lifted. When the hair is lightened, the darker pigments are removed first, revealing the warmer tones underneath.
Any time you go lighter than your natural color, you will bring up your natural underlying pigments.” Brown and black hair have darker orange and red underlying pigments than naturally blonde hair, which is why these hair colors tend to turn more brassy once lightened.
The fading of black hair dye to a brassy reddish color is a common issue and can be attributed to several factors: Oxidation: Hair dye contains pigments that can oxidize over time when exposed to air, light, and heat. This process can cause the darker pigments to fade, revealing underlying warm tones.
That's because the hairs natural pigment has been exposed. If the hair is really dark it will go through a red/orange/yellow phase. The lighter your hair, the less naturally occurring pigment you have (so yellows), the darker your hair the more red you have.
Try using a toning shampoo containing blue, purple, or green pigments to remove the red, orange, and yellow tones. Secondly, always wear a hat or use UV protectant spray to prevent sun damage, which leads to oxidization.
Melanin goes through significant pigmentation changes throughout a person's life. In other words, your hair color doesn't stay the same color. This is why a blond child may become closer to a brunette in their teen and adult years. The sun's UV rays can break down (oxidize) your hair's melanin.
What does sun damaged hair look like? There are several signs that you've got sun-damaged hair. Firstly, its colour may begin to lose its vibrancy and lustre; you may also notice that your colour becomes lighter and brassier, as excess sun exposure can bleach your hair.
Except when people are of mixed ancestry, red hair in Africans is usually caused by a kind of albinism. When people think of albinism, they may picture people with white hair, pale skin and pink eyes. But the reality is different! Albinism comes in many different varieties, and can look different on different people.
Vitamin A, C and B12 are the most needed vitamins to increase the melanin production in your hair. Add citrus fruits like oranges, grapes, pineapple, and melon to your diet. Also eat vegetables like potatoes, carrots, beans, etc. Non vegetarians can try adding red meat, chicken liver, fish, and eggs to their diet.
Environmental Factors: Certain factors like exposure to the sun can cause black hair to lighten, taking on a red, copper, or even blonde hue. Natural oils produced by the scalp may also interact with the sun's ultraviolet radiation to alter hair color over time.
Violet hued shampoos will neutralize yellow brassiness. Blue (silver) toned shampoos will cancel out copper brassiness.
Bleach your hair (optional). If you have dark hair, you may need to bleach it first in order to achieve a bright copper color.
If you have dark brown to black hair
If you're someone with a darker hair color and have chosen a permanent color that is more than two shades lighter than your natural color, chances are that your hair will come out with a brassy orange color – and there's science behind it.
Brassy brown hair happens in color-treated brown hair and refers to the orange and red undertones that appear in the base color over time. When hair is lightened, the pigments are stripped, which leads to these unwanted warm tones that come to the surface.
Greying of hair, also known as greying, canities, or achromotrichia, is the progressive loss of pigmentation in the hair, eventually turning the hair grey or white which typically occurs naturally as people age.
While it is relatively rare, it is possible for Black individuals to have different eye colours, including blue, green, or hazel. Eye colour is primarily determined by the amount and distribution of melanin in the iris, which is influenced by genetic factors.
Sun exposure, hard water build-up, diet, and even certain deficiencies such as Vitamin B12 could be responsible for this color shift. Age, genetics, medications, stress, and diet can also induce changes in hair color, potentially leading to a red hue (source, source).
To put it simply, brown hair can look red in the sun due to the UV rays having a “bleaching” effect on your locks, revealing the underlying red tones in your hair.
A damaged hair strand refers to a hair fiber that has lost its natural structure and strength due to various factors such as heat styling, chemical treatments, and environmental stressors. Damaged hair strands may appear dry, brittle, and dull, and can also have split ends and frizz.
Coconut oil can have many benefits for your hair and scalp. It is used to relieve dandruff, restore luster to dry and damaged hair, tame frizz, and protect hair against styling damage. It is safe to use on all hair types.
Hair naturally contains pigments, primarily eumelanin (which gives black and brown tones) and pheomelanin (responsible for yellow and red hues). When exposed to UV rays, the sun oxidizes these pigments, breaking them down, which makes underlying warm tones, especially the red and yellow pigments, become more visible.
Oculocutaneous albinism (OCA) is an inherited form of hair color change that affects hair globally. In OCA type 1, where tyrosinase activity is absent, hair is diffusely white. In OCA type 2, pigmentary dilution leads to yellowish hair, and in OCA type 3 (rufous albinism), hair is orange or red.
Exposure to Sunlight: The ends of your hair have been exposed to the sun and other environmental elements for a longer period than the roots, leading to natural lightening. Age: As we age, hair follicles produce less melanin, the pigment that gives hair its color, leading to lighter hair, especially at the ends.
As you get older, your hair follicles may produce less eumelanin, allowing pheomelanin to become more prominent.
