When Does Curly Hair Come In? An Expert Explains

The question of “when does curly hair come in” has sparked curiosity among individuals with straight or wavy hair who yearn for those luscious curls. The answer, however, is not as straightforward as one might assume. The development of curly hair is influenced by a complex interplay of genetic, environmental, and hormonal factors.

Understanding the Genetics of Curly Hair

The formation of curly hair is primarily determined by genetics. The shape of hair follicles, which determines the curvature of hair strands, is influenced by the presence of certain genes. Genes responsible for curly hair are often inherited from both parents, but the exact inheritance pattern can vary.

The Role of Hormones in Hair Curvature

Hormones play a significant role in hair growth and development, including the formation of curls. Androgens, such as testosterone, are known to promote straight hair, while estrogens favor curly hair. This explains why some individuals experience a change in hair texture during puberty or pregnancy, as hormone levels fluctuate.

Environmental Factors and Curly Hair

While genetics and hormones are the primary determinants of curly hair, environmental factors can also influence its development. Exposure to humidity, for instance, can cause hair to swell and become more prone to curling. Similarly, certain hairstyles, such as tight braids or buns, can temporarily alter hair texture and create the appearance of curls.

The Developmental Timeline of Curly Hair

The timing of curly hair‘s appearance can vary greatly from person to person. Some individuals may notice curls from infancy, while others may not develop them until later in childhood or even adolescence. This variation is due to the complex interplay of genetic and environmental factors mentioned earlier.

When Curly Hair Loses Its Curl

Just as curly hair can come in at different times, it can also lose its curl over time. This can occur due to various reasons, including:

• Age: As we age, our hair follicles can become weaker, leading to straighter hair.
• Hormonal changes: Pregnancy, menopause, and other hormonal fluctuations can affect hair texture.
• Chemical treatments: Hair straightening treatments, such as relaxers and keratin treatments, can permanently alter hair structure and remove curls.
• Heat styling: Excessive heat from blow dryers and flat irons can damage hair and cause it to lose its curl.
