It’s very important to understand the hair growth cycle in order to recognize and understand many of the problems you can encounter with your hair. The hair growth cycle consists of three distinct stages – anagen, catagen and telogen.
Hair loss, hair thinning and problems with hair growth occur when your growth cycle is disrupted. This can be triggered by conditions such as metabolic imbalances, illness or improper nutrition.
For instance, 6 weeks after restrictive dieting or a high fever you can experience telogen effluvium (diffuse hair fall). This occurs when your anagen phase is cut short and many hairs enter the telogen phase all at the same time. If your hair growth cycle is constantly challenged, or not supported, you may find that your hair won’t grow as long as it used to. This is because your hairs are never allowed to stay in the anagen (growing) phase long enough for your hairs to reach the desired length.
