You do not usually end life with the same bunch of hair that you grew up with when you were born. Unlike the eyes or nose, your hair keeps regenerating, shedding and growing.

As you turn older, you start experiencing hair loss. This natural process of ageing starts when you turn 50. However, for some people the process starts much earlier. This article examines the various causes of hair loss in men and women.

#1 Stress and Lifestyle

The fast and hurried lifestyles of today make many compromises on your diet. Emotional upheavals can cause health complications that have an adverse impact on the quality of your hair. Lack of cleanliness of the scalp and excessive dandruff problems can also cause hair loss.

#2 Hormonal imbalances

Hair growth and health depends on hormones such as thyroid and pituitary glands. Any disorders in these glands can cause hair loss. The excessive presence of a component of the male hormone - DHT can also cause hair loss. This is a genetic predisposition.

#3 Genetic factors

Inherited causes of hair loss effect the unlucky that have a family history of premature balding. In men, it is called Male Pattern Baldness, in which the hair starts receding first at the temples in a classic 'M' shape. In women, it is called Female Pattern Baldness. This is less common. It starts at age 30 and is characterized by overall thinning of hair.

#4 Side effects

Certain drugs taken for other purposes can cause hair loss as a side effect. The following is a possible list of medicines and drugs that could cause hair loss.

Cholesterol-lowering drugs
Ulcer drugs
Anticoagulants
Agents for gout
Drugs derived from Vitamin A
Anticonvulsants taken for epilepsy
Antidepressants
Blood thinners
Anabolic steroids
Chemotherapy Drugs

However, not all prescription drugs under these categories have hair loss as a side effect. This has to be checked with the doctor.

#5 Other factors

Research is being continuously conducted on the causes and solutions for hair loss. Recently, Japanese scientists concluded from studies that excessive sebum could clog the hair roots and cause hair loss. An excessive intake of some nutrients such as Vitamins A and E can actually promote hair loss.

There is no dearth of solutions, prescriptions and treatments available for hair loss. Every once in a while, a new 'wonder' drug such as Rogaine will enter the market. Not every solution will cure hair loss. The correct diagnosis has to be made before deciding on a course of action for hair loss.
