The average person – both male and female – has 100 000 hairs. Approximately 100 of these hairs are shed each day as part of the hair growth cycle. Similarly, 100 new hairs commence growing each day, resulting in a constant head of hair. Hair shed in this way is natural and is no cause for concern. Problem hair loss occurs when either more than 100 hairs are shed each day or when the 100 hairs that are shed naturally each day are not replaced by new hairs. In both instances, hair loss exceeds hair growth, and if left unchecked, will eventually lead to thinning hair.
Causes of behavioural hair loss?
A stressful lifestyle can result in nutritional deficiencies and therefore your scalp and hair follicles may not get all the nutrients required for normal hair growth. Environmental pollution also places extra stress on your hair and scalp. Pollutants on the scalp may result in an unhealthy scalp environment. Build-up of debris could block follicles resulting in thinner hair. Pollutants and a stressful lifestyle can contribute to thinning hair.
A lack of essential nutrients in our every day diet can be detrimental to normal hair growth and can result in hair falling out of its normal hair growth cycle.
Some medication can cause a decreased absorption or availability of nutrients necessary for normal hair growth and can result in abnormal thinning of hair density.
Infections & Illnesses
Infections or illnesses can result in a decreased availability of nutrients that are essential for normal hair growth to the scalp and hair follicle. This can result in abnormal thinning of hair density.
