Top 10 Awesome Hair Facts 

Hair is one of the coolest features the human body owns. It reflects beauty, style, and personality, while at the same time carrying biological roles and showing one's state of health. Despite such an important position in our life, most of us never know the impressive science surrounding hair. So here are 10 cool facts that will blow your mind.

1. Hair is the Second Fastest Growing Tissue in the Body
Hair is one of the fastest-growing tissues in the human body, second only to bone marrow. On average, human hair grows about 0.5 inches (1.25 cm) per month or around 6 inches (15 cm) per year. However, this growth rate depends on factors like age, genetics, diet, and overall health.

Fun Fact:If a person never cuts their hair, it would grow to 30 feet in their lifetime!

2. Hair is Composed of Keratin
Hair is made up mainly of a protein called keratin, the same one that makes up our nails and the outer layer of our skin. Keratin is a tough and elastic protein that gives hair its strength and elasticity. Curious, keratin also makes the horns, hooves, and claws of animals.

Bonus Insight: While your hair feels alive, the strands themselves are dead tissue. Only the follicles embedded in your scalp are living.

3. Hair Color- Genetics and Pigments
The natural color of hair is determined by the melanin pigments present; the type and amount of melanin determine the color. Of the two primary types, eumelanin contains black and brown hues and pheomelanin contains red and yellow tones. A combination of both creates the spectrum of the natural hair colors.

What About Gray Hair? As we age, the pigment-producing cells in our hair follicles gradually die, which causes the gray or white color of our hair.

4. Hair is Surprisingly Strong 

Hair may look very weak and fragile, but it can withstand up to 100 grams of weight with one strand of hair. Cumulatively, all of the hair on one's head can potentially support the weight of two elephants!

Pro Tip: Avoid overprocessing and exposure to excess heat to keep up with this strength.

5. We Lose Approximately 50-100 Hairs per Day
It's totally normal to lose somewhere in the range of 50 to 100 hairs a day. Shedding is part of the natural life cycle of the hair. This cycle has growth or anagen, rest or telogen, and shed or catagen stages.

When to Worry: Significant hair thinning or bald patches may be an indicator of underlying health issues, such as stress, hormonal imbalance, or nutrient deficiencies.

6. Hair Can Reveal Your Health
Hair can act as a diagnostic tool for your overall health. The texture, strength, and quality of your hair can reflect your diet, stress levels, and even medical conditions.

Example:Hair loss or thinning can be an indicator of iron deficiency, thyroid problems, or stress. Brittle hair may be a sign of dehydration or malnutrition.

7. Everyone Has Different Hair
Just like fingerprints, every person's hair is unique in texture, color, and growth pattern. Even identical twins have slight differences in their hair characteristics due to environmental factors and lifestyle.

Did You Know? On average, every human scalp has about 100,000 to 150,000 hair follicles. Actually, blondes have relatively more hair strands-about 150,000 while on the other hand, people with red hair have fewer than the others, that are approximately 90,000.

8. Hair grows faster in summer
Human hair grows slightly faster in summers. It is because warm climatic conditions stimulate the amount of blood circulation. Similarly, metabolism in the human body increases in summers leading to hair growth.

Tip for Growth: Scalp massages and balanced diets rich in vitamins and proteins can further enhance hair growth.

9. Hair is Waterproof
Hair is hydrophobic by nature. It means that it has the tendency to repel water. This will help prevent water from getting into the strands and weakening it. The cuticle of the hair shaft is the outermost layer and plays an important role in this protection function.

Why Does Hair Feel Heavy When Wet? Although hair repels water, it can absorb up to 30% of its weight in water, making it feel heavy.

10. Humans Have Hair Everywhere Except a Few Places 
Hair covers almost every part of the human body except for the palms, soles of the feet, lips, and certain parts of the genitals. Even areas that appear hairless, like the forehead, have tiny, fine hairs called vellus hairs.

Interesting Evolutionary Fact:Over time, humans lost most of their body hair to adapt to their environments. However, scalp hair remained to protect the brain from UV rays and regulate body temperature.

Bonus Fact: Hair Can Live Long After Death
Hair, and nails, can still seem to grow for days following a person's death. This is a myth however, as it's created by the dehydration of the skin, which contracts back and makes the hair and nails appear longer.

Conclusion
Hair is far more than just a beauty accessory. It is a complex, multifunctional structure with a fascinating biology and history. From its rapid growth to its unique properties, hair continues to amaze scientists and stylists alike. Understanding the science of hair can help you take better care of it and appreciate its role in your identity.

So, next time you run your fingers through your hair, remember it is not just strands of keratin—it is a biological marvel!
