According to the provided information, a moustache became brown because the melanin pigment in its hair cells lost its ability to give color. This change in the melanin's properties can be attributed to factors such as poor nutrition, stress, or genetic factors.
Understanding Hair Color
The natural color of hair, including a moustache, is primarily determined by a pigment called melanin. This pigment is present in the cells of the hair follicles. Different types and amounts of melanin produce the wide range of hair colors we see, from black and brown to blonde and red.
Factors Influencing Moustache Color Change
Based on the provided reference, certain internal and external factors can affect the melanin in hair. These factors include:
- Poor Nutrition: Lacking essential nutrients can potentially impact the health and function of cells, including those responsible for producing or maintaining melanin.
- Stress: High levels of stress are suggested as a factor that can influence the body's processes, potentially affecting hair pigment over time.
- Genetic Factors: An individual's genetic makeup plays a significant role in various biological processes, including how and when melanin is produced and how its properties are maintained throughout life.
The reference specifically states that due to poor nutrition, stress or genetic factors, the melanin pigment may lose its color giving properties.
How Melanin Affects Moustache Color
When the melanin pigment in the hair cells loses its color-giving properties because of the factors mentioned above, it can result in the hair changing color. In this specific case, the reference indicates that this loss of color-giving property can lead to the moustache hair turning brown. This is distinct from complete melanin loss, which typically results in grey or white hair.
Essentially, the pigment is still present, but its functional ability to impart color is diminished, leading to a brown appearance as described in the source.
