Yes, hair can change from straight to curly, or vice versa.
Factors Affecting Hair Curls
Several factors can influence hair texture, leading to changes in curl pattern:
-
Hormonal Changes: Puberty, menopause, and pregnancy significantly impact hormone levels. These fluctuations can alter hair's structure, causing a shift from straight to curly or vice versa over several months. This is directly supported by the provided reference: "During puberty, menopause and pregnancy, many people will find their hair will go from straight to curly or vice versa over a period of months."
-
Stress: Prolonged periods of stress can also affect hair texture, potentially inducing changes in curl pattern. The reference notes this as well: "It's also interesting to note that even long periods of stress can be enough to change the texture of your hair."
-
Other Factors: While not explicitly mentioned in the reference, other factors such as genetics, diet, and hair care practices can also contribute to changes in hair texture over time. However, hormonal shifts and stress are specifically highlighted as impactful causes.
Understanding Hair Texture Changes
It's important to understand that these changes are usually gradual and occur over a period of months. The shift isn't instantaneous. Furthermore, the degree of curl change can vary greatly depending on individual factors.
