Your burning hair related questions answered by Toppik
We've previously considered some of the wild and not so wild myths told about hair, but perhaps even more surprising are some the facts about this incredible structure. Toppik answers some of the most commonly asked questions about hair.
How strong is hair?
For its size, a single strand of hair is incredibly strong. Maybe not as strong as steel, but certainly a match for aluminium, copper or kevlar. The disulphate bonds in your hair are the strongest naturally occurring bonds. These bonds can be broken by chemicals and heat though, so be careful of harsh products and your curling tongs!
How far can a hair stretch?
Hair when healthy and dry can stretch up to a third of its length before breaking. When wet however it absorbs water and can stretch a good deal further, especially if damaged. Wet hair, however, is particularly susceptible to being overstretched and broken, hence why you should never brush your hair when wet.
How fast does hair grow?
Hair is a remarkable substance, it grows at a rate of half an inch per month, making it the fastest growing of any part of your body other than the marrow in your bones.
Does hair always grow?
Your hair grows in cycles, it has a growth phase, known as the anagen stage. This phase can last for as long as five years at a time. From there, your hair enters an intermediary stage knows as the catagen stage, from there it moves to the telogen stage, where hair is shed and the follicle it grew from rests for a few months. At any one time, around 90% of your hair follicles are actively growing hairs.
Why does hair get thinner with age?
Hair follicles are the tiny pockets in your skin from which your hairs grow. When you're born, you have all the hair follicles you'll ever have, you can't make more. As you age, hair follicles stop working at a rate which is mostly determined by genetics. Once you've lost around half of your hair follicles their absence starts to become noticeable as hair loss.
What is hair made from
One of the most common hair related questions. For the most part, each hair strand is composed of two to three layers of a protein called keratin. This is the same substance the outer layer of your skin is made from, it's also responsible for giving your nails their hardness. The beaks, claws, horns and hooves of animals are also constructed of this versatile protein.
Do blondes really have more fun?
There's no definitive answer to that one, but blondes DO have more follicles. Naturally blonde hair is finer than many other hair colours, so the follicles take up less room on the scalp and consequently more can be squeezed into the same space.
