What Makes Hair Curly ?

By


If you like your curly hair, you can thank, your genes, your shampoo, your climate and your hairdresser. But the fact is they’re all bit players.

When we touch our skin, it feels very smooth, but when we observe it under a microscope, it looks like this -



           


A notched mountain range with large holes sprouting hair. 

These pits are known as follicles, and they're responsible for making hair straight or curly. Straight hair are produced by round follicle, wavy hair are produced by an oval-shaped follicle and very curly hair are produced by a flat follicle. 

The texture of hair chiefly relies upon the shape of the hair that can be observed in cross-section under a microscope. The shape of straight hair is round, that of wavy hair is oval and that of curly hair is flat. 

The number of hairs depends upon your being brunette or blond. Blonds have around 1,40,000 hairs on their head and redheads have an average 90,000 hairs and the people who have black or brown color, they have about 1,10,000 hairs. Most of the hair follicles have oil glands, which are also known as Sebaceous glands. This gland emits oil into the follicle and this oil strengthens hair, lubricates it and makes it soft.  

Quick Facts 

  • Hair grows with about 1 cm every month.
  • Hair is made mostly of a protein called keratin.
  • Human facial hair grows faster than any other hair on the body.
  • On average, we lose 50 to 100 strands of hair a day from the scalp.
  • Human hair grows faster in warm weather because it stimulates hair growth. 
  • When people become old, their hair becomes either Grey or white because the pigment called melanin, which provides color to the hair forms no longer.

Nutcase Couple Hang From Cliff 2700ft Above Rio

By
While most people get a little bit worried about heights when climbing up a ladder, Leonardo Edson Pereira, 23, and his girlfriend Victoria Medeiros Nader, 18, are very different. In fact, after seeing images of the couple hanging off a 2,700 ft cliff in Rio, Brazil, it’s safe to say the couple pretty much break the mould when it comes to heights and being daredevils. Pereira took his girlfriend with him on his latest thrill seeking adventure, with Pedra de Gavea their conquest this time. The images really are breathtaking and depict just one of the many times Pereira has climbed the Pedra de Gavea. He claimed: "I love living on the edge! I know people think it’s dangerous and crazy but it makes me feel alive,’ Leonardo says. It is really high and I do just hang on using my arm strength. I have to trust myself not to fall." The literal translation of the rock’s name means ‘Rock of the Topsail’, and while the images certainly are something, given ...

What Is The Largest Number?

By
Humans have been using numbers for thousands of years. It is believed that the concept of numbers first originated when prehistoric humans began using their fingers to count. This eventually evolved into sign language and then tally marks on objects like sand, walls and sticks. We’ve come a long way. Now we use calculators and computers to count our large numbers. We even have a word for numbers that are without a limit. Sometimes, it seems like the only people who can make sense of it all are the mathematical savants. One reader wanted to know: What is the largest number in mathematics? NOT SO OBVIOUS So what’s the largest number? The answer should be pretty obvious. Infinity, right? But that’s not entirely correct. Infinity in the strictest sense, is not a number at all. It’s a concept. An idea. And a mind bending one at that. Infinity is a concept which means “a quantity without bound or end”. The definition of infinity in mathematics states that no matter how big a nu...
