So, an understanding of how hair grows and the factors affecting is very essential to understand hair loss.
The most important part of your hair is the "hair follicle". Follicles helps hold your hair strands on the scalp and nourishing them. The average lifespan of a single strand of hair is around 4-5 years. During this period, the follicle also goes through a life cycle which consists of the following stages:

* The Anagen/active phase (childhood, teenage and most of active adulthood) comprises around 85% of its life span. The longer the hair stays in this stage, the better it is for hair growth.

* The Catagen/transitional  phase lasts for around 2-3 weeks. This is when the hair follicle shrinks to 1/6th its size, hair is detached from its blood supply and stops growing but doesn’t necessarily fall out.

* The Telogen/Resting phase is the last phase which lasts for around 2-4 months(App.10-15% of hair). The hair still doesn’t fall off at this stage but may loss since it is lacking blood supply and is loosely attached to the scalp.

* When the hair moves from the Telogen to the Anagen phase again, hair loss occurs and forms new by pushing the old one out. About 50-100 strands per day are lost due to this normal cycle.

Factors affecting the hair growth are:
*Hormonal factors: Childbirth, Hormonal deficiencies, Birth control pills, Stress
*Disease/Illness: Local infections of scalp (ringworm), Severe systemic infections, Major surgery, Chronic illnesses, Cancer treatments, Thyroid disease
*Deficiencies in diet – Low protein, Low serum iron, Anorexia, Bulimia
*Medications: Drugs used for Gout, Arthritis, for thinning blood, for Depression, for Heart problems.
*Mechanical causes: Behavioral problems like hair pulling (Trichotillomania), Incorrectly done chemical hair treatments, Hairstyles like tight braids.
Whatever the cause, the treatment has to be done by taking all the possible factors.

The normal cycle of hair growth lasts for 2 to 3 years. Each hair grows approximately 1 centimeter per month during this phase. About 90 percent of the hair on your scalp is growing at any one time. About 10 percent of the hair on your scalp, at any one time, is in a resting phase. After 3 to 4 months, the resting hair falls out and new hair starts to grow in its place.

It is normal to shed some hair each day as part of this cycle. However, some people may experience excessive (more than normal) hair loss. Hair loss of this type can affect men, women and children.

Hair loss affects men and women in different ways and can have a dramatic impact on our lives. Hair loss will affect most men at some point in their lives and it affects many women too to some degree. DHT, or Dihydrotestosterone in full, is a steroid and hormone that plays an influential role in hair loss. Find out more about DHT and how you can mitigate its effects in our blog post.
