Cause Of Thinning Hair

In knowing the causes for thinning hair, we have to know a little bit about the growth cycle of hair. Doctors have figured out that hair grows in three main phases. One is the anagen cycle. This cycle is the two to six year growing phase of the hair. The next is the catagen. This is the transitional phase which should last only three weeks. The last is the telogen phase, which is the resting phase.

People who have normal hair that have entered the telogen phase remains formant in the scalp for two to four months. The hair is then shed, and new hair will start to grow from the same bulb as it pushes it out. Hair is growing, but you do not easily see them. Sometimes the nearly invisible hairs are called vellus hairs.

So when we look at the cause of thinning hair, we can tell that before the bulbs on your scalp whither away and are no longer able to produce hair, they replace the thick hair that you are used to seeing with skinny hairs that are hardly noticeable. Those are the vellus hairs that we mentioned. If you look carefully in a magnifying mirror, you can see some of these vellus emergency from empty follicles. When it comes to male pattern baldness, this is what you will find and is a major cause of thinning hair.

So while at that given moment you are looking at the cause of your thinning hair, you can determine, that you may not necessarily have lost all of it just yet. Those little hairs will still be present. The thinning hair can last for many years before you actually see any real baldness.

Also when looking for the cause of thinning hair, there is the genetic link that has to be looked into. Levels of testosterone derivatives known as dihydrotestosterone are found within follicle cells and play a roll. There are two kinds of proteins that are found on the cell membranes. One group of proteins that is looked at in causes for thinning hair is the proteins that receive testosterone. The other group repels it. This is so the follicle can balance the amount of hair grown on the body.

How many of these protein receptors that we have seems to be determined genetically. Most male patterns of baldness are passed on genetically. Which can be a cause of thinning hair. Men and women who have a testosterone-receptive protein can have an overload of DHT in the hairproducing cells. That is most likely linked to hair loss as they go through life and is a cause of thinning hair.

When DHT becomes more active, it reacts with the sebum and cholesterol that is found on the follicles. It then slowly narrows the tiny opening causing the follicle to become shorter and more shallow. Whent his happens the lifespan of hair that is growing is shortened and will fall out sooner than it normally will. These are the major reasons for the cause of thinning hair.
