The primary reason your hair likely became wavy after puberty is due to hormonal changes, specifically an increase in estrogen levels.
Hormonal Shifts and Hair Texture
During puberty, the body undergoes significant hormonal changes. For girls, this includes a notable rise in estrogen.
- Estrogen's Role: As estrogen levels increase, they can affect hair follicles.
- Hair Texture Change: This hormonal shift can alter the shape of the hair follicle, causing straight hair to become wavy or curly.
- The change is not sudden; it develops gradually through puberty.
Summary of the Impact of Estrogen on Hair
| Hormone | Effect on Hair |
|---|---|
| Estrogen | Can change the shape of the hair follicle, leading to straighter hair becoming wavy or curly. |
Reference: Estrogen is the hormone responsible for feminine traits like breast development, wider hips, and hair curl. As estrogen levels rise during puberty, many straight-haired girls will notice their hair taking on a wavy or curly texture.
In short, the rise of estrogen during puberty significantly influences your hair's texture, and that’s why many women find their hair becoming wavy or curly during this time.
