What are the common hair loss causes?
One of the most worrying aspects of hair loss treatment is the tendency of so many people to seek solutions without first determining what has caused their loss in the first place.
At best, sufferers may waste money on inappropriate 'wonder cures' or even legitimate treatments that unfortunately are not suitable for their particular needs. At worst, some people may be risking their health by self-prescribing powerful pharmaceutical drugs. I don't have a problem with hair loss sufferers saving money by purchasing cheap generic drugs on the internet, but I feel strongly that they should at least seek confirmation from their physician that a given drug matches their individual needs.
Before examining the most common causes of premature hair loss we need to understand that some shedding of hair is perfectly normal. Hairs grow from follicles that are tiny organs in the skin designed to grow a single hair that follows this repetitive cycle:
1. Lengthy growth period (Anagen Stage) - this phase usually lasts between two and seven years with an average growth rate of six inches (15cm) each year.
2. Short transition period (Catagen Stage) - this period of transition lasts for roughly two to four weeks. During this phase the hair shaft becomes detached and moves upwards within the follicle.
3. Resting period (Telogen Stage) - this phase lasts about three months allowing the hair to detach itself prior to falling out.
At this point a new hair begins to grow thus repeating the normal cycle of hair growth. Unfortunately a number of factors can interfere with the natural hair growth process leading to forms of hair thinning or premature baldness.
