15 Factors That Make Hair Curly: Unraveling the Science Behind Your Locks

This article explains the science behind curly hair and presents creative ways to style it.



Curly hair is often inherited, with specific genes determining the curl pattern passed down from parents to offspring.



Fluctuations in hormone levels can alter the texture and curl pattern of your hair over time.



Humidity swells the hair strand, enhancing the curls by disrupting hydrogen bonds within each hair.

Heat Styling

Chemical treatments alter hair’s structure to produce or enhance curls through permanent reshaping.

Hair Follicle Shape

Curly hair roots from the asymmetrical shape of the follicle, causing strands to spiral as they grow.

Sulfur Bridges
