What causes hair discoloration in adults?
Several factors can cause hair discoloration in adults, including:
1. Genetics: Hair color is determined by the genes inherited from both parents. Genetic variations can lead to different hair colors, including blonde, brunette, redhead, and black.
2. Age: As people age, their hair follicles gradually produce less melanin, the pigment that gives hair its color. This can result in gray or white hair.
3. Hormonal changes: Hormonal changes, such as those that occur during pregnancy, menopause, and certain medical conditions, can affect hair color. For example, pregnancy hormones can cause hair to darken, while menopause can cause hair to gray or lighten.
4. Medical conditions: Some medical conditions, such as thyroid disease, anemia, and vitamin B12 deficiency, can cause hair discoloration.
5. Medications: Certain medications, such as chemotherapy drugs, can cause hair to lose its pigment or change color.
6. Environmental factors: Exposure to sunlight, pollution, and harsh chemicals can cause hair to fade, turn brittle, or change color.
7. Lifestyle factors: Smoking, stress, and poor diet can contribute to hair discoloration.
It's important to consult a healthcare professional if you notice a sudden or significant change in your hair color, especially if it's accompanied by other symptoms, to rule out any underlying medical conditions.
