Why Does Hair Grow? By Monica C. At Isnare.com Ezine Articles

The human hair doesn’t simply grow out of the skin like it had immeasurable organic resources. Hair is not like fresh grass that you can just cut, cut, and expect that nothing would happen. Upon closer examination, it would be revealed that the business of growing hair is more complex that it looks.

The Dermal Papillae

As you might have already come across in other references, the dermal papillae are actually the hair ‘originators’. This is because it is in these biological sites that hair cells are continually reproduced and transformed to the hair shaft, as we know it.

What happens when the dermal papillae are destroyed? In certain cases, like second-degree burns and failed attempts at a hair transplant, the dermal papillae’s basic structure might be altered for good. Does this mean that these sites will halt in producing hair cells?

Fortunately, the answer is a resound “no”. The human body is so efficient in repairing and regenerating itself that damaged dermal papillae are actually regenerated and re-activated when the skin reverts to some condition of normalcy.

Will the hair look the same after such situations? Unfortunately, the answer to this question is still a “no”. This is the basic problem of very basic hair transplantation methods. Usually, when these biological sites are cut from the underlying tissue, the hair produced becomes irregular, fuzzy and thinner than normal.

How Hair Erupts from the Skin?

Do hair strands emerge one by one? Nature decided that this would be too organically taxing for the primordial cell reproducers, so the human body was able to devise a more efficient method of reproducing hair strands.

Hairs actually emerge at the surface of the scalp in groups. These groups are composed of more than three hair strands at a time. Then eventually, these hair strands find their own place on the scalp and begin to mature, until their cortexes are fully-grown.

How Healthy is Your Hair?

We could adjudge health by looking at the amount of organic reproducibility there is. Terminal hairs on the scalp under normal conditions are continually protected by non-terminating papillary processes. Young adults and males who are not suffering from male-pattern baldness have at least 90% of their terminal hairs under the anagenic phase.

How Long Does Hair Grow Each Month?

For something composed of mostly dead cells, human hair grows surprisingly quickly. The estimated rate for hair growth has been aptly estimated at 0.44 millimeter a day (about 1/2 inch a month). Some healthier scalps have faster growth rates, while some experience an inverse condition: the growth is very slow.

How long does hair stay ‘alive’ (in the anagenic phase)? Fortunately for us, we shed our hair every five months. This means that damaged terminal hairs would be replaced by healthier, more robust hairs. What happens when the telogenic phase begins?

Again, under normal circumstances, the old hair shaft is simply pushed out by the newcomer (the new hair shaft). In male patter baldness, the hair falls out but is never replaced by new hair shafts. This is what modern science wishes to explore further: can certain devices stimulate the scalp once again into producing new hair?
