What factors can affect hair texture?

Hair texture is influenced by a combination of genetics, hormonal changes, and environmental factors. Genetics plays a crucial role in determining the fundamental characteristics of hair, such as its thickness, curl pattern, and overall health. These inherited traits dictate the shape of the hair follicle, which in turn affects how straight, wavy, or curly the hair will be.

Hormonal changes can also significantly impact hair texture. For instance, fluctuations during puberty, pregnancy, or menopause can lead to changes in sebum production, hair growth cycles, and even the body's overall metabolism, resulting in alterations to the texture of the hair.

Environmental factors add another layer of complexity. Elements such as humidity, temperature, and exposure to chemicals (like those found in hair products) or pollutants can affect the hair's moisture levels, leading to changes in texture. For example, high humidity can cause hair to swell and appear frizzier, while dry conditions can make hair feel brittle and coarse.

Taking these factors into account provides a comprehensive understanding of why hair texture can vary significantly from person to person and even change over time for the same individual.
