Understanding Hair Growth Cycles And Hair Decline
Understanding Hair Growth Cycles And Hair Decline We all lose a certain amount of hair each day - anywhere from 50 to a hundred to a hundred twenty five hairs. True hair decline takes place when these hairs we lose don't grow again, or when the amount of hair we lose each day exceeds this normal range. Idea: More than 60% of adult men have some kind of decline of hair, starting in their mid-twenties everyone must get ready for it. DHT is a byproduct of testosterone, and hunts down your hair and damages it, so particular things must be done to reduce your chances of this happening. Hair decline can occur as a result of medications, such as chemotherapy treatments or blood thinners, which can damage the telogen hairs, or stop the natural cell division that then produces weakened hair that is susceptible to breaking. High doses of vitamin A can also guide to hair decline as well. The most common type of hair decline, however, is where more and more hair follicles enter what is called the resting phase (telogen phase) in the hair growth cycle. Idea: If you are a male experiencing excessive hair decline, there is a good way to relieve into accepting it. If you are losing your hair, there are some haircuts that will still look good on you. Overall, hair grows continuously from the scalp, but it moves away from the scalp in 3 phases. Hair is not all uniformly in one phase. Different parts of the scalp will be in different phases, so at any one time you should have hair follicles in all 3 levels. Generally, most (90%) of the hair will be in the anagen phase, 10 to 14% of the hair will be in the telogen phase, and only 1 to 2% of hair in the catogen phase. Idea: Take in more vitamin C if your want to reduce hair decline. It helps the blood flow and makes your capillaries stronger. The first phase is the Anagen phase, which is the growth phase. This can last anywhere between 2 and 8 years. A shorter anagen phase will limit how long your hair can grow. Hair cells at the root divide rapidly, which lengthen the hair shaft. Idea: If you're worried about your hair thinning, then encourage hair growth by stimulating your scalp. You can do this by brushing dry hair and your scalp with a hard bristle brush. In the next phase, the catagen phase, the outer root of the hair follicle shrinks and attaches to the root of the hair. Hair growth stops here. This phase lasts 1 to 2 weeks. Idea: Your hair style may be contributing to your hair decline. Avoid excessively pulling your hair, or keeping it tied limited with a rubber band. The telogen phase is the resting phase. This lasts from 5 to 6 weeks in normal hair. Hair doesn't grow in this phase, but it stays firmly rooted in the scalp as long as the follicle stays in a resting phase below it. New growth commences at the end of the resting phase, and this is when natural hair shedding will happen, as the new growth pushes the old hair out. In male pattern baldness, more hairs enter the telogen phase. This effects of this are an increase in hair shedding. Hair gradually becomes thinner and shorter, and in the end, the hair follicles shut down.
