Why is the hair curly
Hair curls are a common phenomenon, and many people will wonder why their hair will be naturally curly. The degree of curl of hair is mainly determined by genetics, hair follicle shape, keratin structure and external environmental factors. This article will combine recent hot topics and scientific data to analyze the reasons for hair curls and attach relevant structured data.
1. Genetic factors
The degree of curl of hair is largely determined by genetic genes. Scientific research shows that hair curls are closely related to the shape of hair follicles. If the hair follicles are oval, the hair tends to be curled; while round follicles are more likely to grow straight hair. Here are the popular data on recent genetic research on hair curls:
| Research Institutions | Discover time | Main conclusion |
|---|---|---|
| Chinese Academy of Sciences | November 2023 | 3 key genes that affect hair curls |
| Harvard University | October 2023 | Confirm the direct association between hair follicle shape and hair curl |
2. Keratin structure
Keratin is the main component of hair, and its structure determines the strength and elasticity of the hair. Curly hair usually contains more asymmetric disulfide bonds, which can cause hair fibers to bend. Here are the recent research data on keratin and hair curl:
| Research topics | Publish a journal | Key Discovery |
|---|---|---|
| Keratin and hair curl | Nature-Genetics | Mutations in keratin genes are found to cause increased hair curls |
| Disulfide bond distribution | "Scientific Report" | Confirm that the disulfide bond distribution in curly hair is uneven |
3. Environmental and nursing factors
In addition to genetic and biochemical factors, external environment and personal care habits can also affect the degree of curl of hair. Here are the hot topics on social media recently about hair care:
| topic | platform | Discussion hot topic |
|---|---|---|
| "How to keep curly elastic" | Little Red Book | 1.2 million+ views |
