Hello, I'm an expert in the field of biology with a focus on human physiology. When it comes to the question of whether beards can change color, the answer is yes, they can. Just like the hair on our heads, beard hair is subject to the same biological processes that can lead to color changes.

Beard hair, like head hair, is made up of keratin, and its color is determined by the presence of pigments called melanin. As a person ages, the cells that produce melanin can gradually decrease in number or stop producing melanin altogether, leading to graying or white hair. This process can also affect the hair in one's beard.

Additionally, certain medical conditions, nutritional deficiencies, or the use of certain medications can also impact the color of beard hair. For example, conditions like vitiligo can cause a loss of pigment in the skin and hair, leading to patches of white or gray.

In summary, beards can indeed change color due to aging, genetic factors, and other health-related reasons.
