Hair waviness is primarily determined by the shape of your hair follicles. Follicles that are round produce straight hair, while flattened or ellipsoid follicles create waves, curls, or kinks. The more flattened the follicle, the greater the wave or curl.
Here are some additional factors that can contribute to hair waviness:
- Hormonal changes: Fluctuations in hormones, such as during pregnancy or menopause, can affect hair texture.
- Mineral levels: Changes in mineral levels, particularly those involved in hair growth, can also alter hair texture.
- Hair thickness: Thicker hair tends to hold curls better than thinner hair.
- Genetics: Hair texture is largely determined by genetics, so if your parents have wavy hair, you are more likely to have wavy hair too.
- Styling techniques: Using heat styling tools or certain products can temporarily alter hair texture.
It is important to note that hair texture can change over time due to various factors. For example, you may have had straight hair as a child and developed waves or curls as an adult. This is because hair follicles can change shape throughout your life.
