During which hair growth stage is hair color typically darker?

• A. Telogen
• B. Anagen
• C. Catagen
• D. Exogen

Answer: (B)

The hair growth stage in which hair color is typically darker is the anagen phase. During this stage, which is also known as the growth phase, hair is actively produced and receives nutrients directly from the follicle. As a result, the melanin production in the hair follicles is at its peak, leading to richer and darker hair color. The anagen phase can last several years, contributing to longer hair lengths and, consequently, a more vibrant color.

In contrast, the other stages have different characteristics. The telogen phase is a resting stage where hair may shed or fall out, making it unlikely for color to be prominent. The catagen phase is a transitional stage that lasts a couple of weeks, where growth stops, and the hair prepares to shed, which does not involve significant color development. The exogen phase is part of the shedding cycle, where hair is released from the follicle, and again, darker pigmentation is not a factor as hair is actively falling out. Thus, the anagen phase is distinctly associated with darker hair color due to active melanin production and nutrient supply.
