Hair loss is frustrating for both men and women. Our hair is a statement of who we are and when our hair becomes thinner and we lose density, it can have an enormous impact on our phycological well being.
The underlying cause for hair loss, regardless of gender, is now believed to be the amount of DHT binding to receptors in the hair follicle ultimately shrinking them and causing thinner hair and eventually loss.
Although all causes of basic hair loss are not fully understood, there are several factors that have proven to contribute to the eventual loss of hair follicles.
Hair loss can be permanent or temporary, as well.
The most common reason is a surplus of DHT (dihydrotestosterone) in the scalp. Although most often testosterone is associated with men, DHT is present in men and women.
The hair's natural cycle is broken into three phases - Anagen, Catagen and Telogen
Roughly 70-85% of the hair on your head is in the Anagen phase of it's life cycle. This is when the hair is actively growing and it lasts from 2-6 years.
When your hair is in the Catagen phase, it is done growing and moving into position near the top of the skin layer in preparation for a new hair follicle to grow in its spot. Roughly 1-2% of the hair on your head is in this phase and it lasts from 2-3 weeks.
The final phase is Telogen phase or resting phase, which lasts for 100 days or so. The remaining hair on your head is in this phase and eventually falls out when the new hair beneath it pushes it out or it is forced out by an activity like brushing, showering or anything else that would put pressure on the hair.*
Eventually over time, the hair cycle will begin to change. The growth phase of hair (Anagen) will begin to shorten.
When this phase shortens, hair can become thinner and more brittle. One of the main underlying causes is increased DHT, which attacks the hair follicle and limits the growth cycle in many ways.
By blocking DHT, the hair's growth cycle can remain full and hair will be thick, strong and grow to its fullest potential.
