Do you think you know a lot about hair? Think again, my friend. Today’s blog post tells ten exciting and fun facts about hair that will surprise you (and hair haha.). Grab a cup of smoothie or some tea, and enjoy reading!
1. Hair is mainly made of keratin.
Keratin is the same protein we find in the outer layer of skin and nails, and surprisingly also makes up the hooves, claws, and feathers of animals. Who knew that we have a lot in common with animal friends?
2. In a warm climate, the growth rate of hair may be faster.
Heat stimulates circulation in the body (including the scalp) and promotes hair growth. Despite this situation, genetics and diet also play an essential role in our hair growth-obviously!
3. Wet hair can be stretched to 30% of its average length.
Have you ever been disappointed when you realize that your recently cut wet hair looks longer? And then found that it shrank suddenly when the hairstylist dried it? Don’t worry; it’s not just you-this happens because water stretches your hair, making it longer than natural stretching!
4. All the hair we can see is dead.
The only hair that is not dead is the hair still inside the epidermis of our scalp-how weird is this? It is surprising because we often focus on the outer hair, and what we should consider very much is that what we put in the body directly affects the hair we can see!
5. Black is the most common hair color, and red is the rarest color.
1% of the world’s population has natural red hair, and the second rarest hair is blonde (2% of the world’s population). Dark colors are the most common, and black is the most common. Embrace natural hair, no matter what color it is!
6. Hair contains essential information, which is used as forensic evidence in experiments.
The scary fact: hair contains information contained in blood in the past. Scientists only need a handful of hair to know your diet, drinking, and environment!
7. Each hair can support up to 100 grams of weight.
To see this through, let us use a mental image. If each of your hair can support 100 grams, and people have an average of 100,000 to 150,000 hairs on their scalp, your entire head can support the equivalent of two elephants-yikes!
8. Hair is the second-fastest-growing tissue in the human body.
The fastest is bone marrow.
9. Blow drying changes the shape of the hair by changing its hydrogen bond.
Water also changes the hydrogen bonds, making our hair smoother after the shower. May explain why some women hate humidity-water in the air can change the silkiness and structure of the hair, causing some hair to become fluffy or fluffy.
10. Cutting hair will not affect its growth rate.
It is unfortunate because many of us are told the opposite and try to reduce too much. However, it is essential to remember that split ends prevent our hair from growing, which means that there is no choice but to cut them when they appear.
