Hair is mostly made of keratin protein which is the same protein which we discover in the layer of our skin and fingernails. You may be surprised that this keratin is also found in our animal friends’ hooves, feathers and claws.
Hair is proven to grow faster in warmer weather. The fundamental behind is due to heat which stimulates blood circulation in the body which includes the scalp. Thus all this promotes hair development and growth. Of course, different individual hair growth rate will still be determined by their genetics and daily nutrition.
Do you know that a wet strand of hair can be stretched up to thirty percent of its typical hair length when it is dry. Are you disappointed that your hair appear to be shorter after it is dry as compared to the moment your stylist has just wet cut hair it. Do not worry, this happened to everyone of us as our hydrated hair indeed stretched to be significantly thirty percent longer than it naturally it.
You may be shocked to know that all the hair that we can see and touch on our scalp is actually dead hair. The only hair that is living is the hair that is hidden and still inside the epidermis of our scalp. But once the hair is at surface of the scalp, the cells within the strand of the hair are dead and that is the reason why when your hairdresser cuts your hair with scissors, there is no pain at all.
The lifespan of every strand of hair is only about two to six years. Thereafter, it will rest for a couple of months before it departs from you. It will normally be replaced by another new hair which begin to develop from that specific hair follicle.

Blow drying of your hair can change the shape of the hair by transforming their hydrogen bonding. Next, we all know that water will immediately make our hair flatter especially after shower due to the alteration of the hydrogen bonds. This is the reason why women dislikes humidity and the water vapour in the air as they changes the hair silkiness and the hair structures entailing puffy or frizzy hair.
Haircut will not affect the growth rate of your hair at all. This is a misconception as several of us have been told the opposite and have been trying to trim our hair frequently. However, another interesting fact is if you unfortunately have split ends, it will cause your hair to stop growing and the only solution is to trim them off so that your hair can continue to grow. Next, people also misunderstood that pulled out hair will stop growing. When we pull out a hair, there will be a bulb at the end of the hair which is the hair root. This is not the hair follicle that our hair actually develops out from, thus the bulb is not responsible for the hair growth. However, please bear in mind that repeat plucking of hair will certainly weaken the hair follicles. Hence many women experience thinner hair or hair growing slower after many years of waxing or plucking their body hair.
Our nose is not the only part of our body that has the ability to smell. Do you know that our hair can smell as well? Experts have researched that hair follicles have exactly the same type of olfactory receptors which line our nasal passage. Such receptors contain odour molecules that can signal our brain there are durian in the house or smelly trashes. However, the strength of hair detecting odours is weaker than nose. The greatest break through is the finding of hair liking the smell of sandalwood and the synthetic version called Sandalore will actually excite the hair follicles that will certainly lead to the boost to hair growth business.
