It is normal to shed hair every day, and at any time we can loose up to 10% of our hair, which is usually not noticed in most heads of hair.

But however, some people experience more hair loss than is normal.

Loosing hair is part of a aging process, called Androgenetic Alopecia, – what is Androgenic Alopecia?
Androgenic alopecia is hair loss that occurs due to an underlying susceptibility of hair follicles to androgenic miniaturization.

It is the most common cause of hair loss and will affect up to 70% of men and 40% of women at some point in their lifetime.

In men it is noticed first by receding hairline and baldness at the top of the head, which most men are conscious of, and try many ways to hide the fact, that they are losing hair.

With women, on the other hand, they don’t go entirely bald even if their hair loss is severe, hair loss is spread out evenly over their entire scalp, but be aware that some women do lose all their hair, but it can be covered up with wigs, and sometimes you will never know about their loss of hair,for years, as i found out about one of my relations.

Sometimes it is only patches of head that have loss hair, but with all the hair pieces available, and clever hair dressers, it can be overcome to make the wearer, feel completely at ease with the hair loss.

Androgenetic Alopecia is only one reason for hair loss, there are other reasons, such as medical conditions, and quiet a few other reason which I will cover in a article later, hormones play the biggest role when talking about hair loss.

Another way in which individuals experience hair loss is due to mechanical stressors on the hair and scalp.

Wearing pigtails, pony tails, cornrows or tight rollers that end up pulling on the hair, can scar the scalp and cause permanent hair loss, also migraine headaches, which is caused by the the constant tension of all the hair being pulled together into a confined spot at the back of your head, and is straining every hair follicle out of it’s natural growth direction which tenses your whole scalp preventing your scalp from free healthy blood flow, which is depriving the scalps blood flow, this could also not help men that have long hair tied back as well.

If hair is coming out in clumps, or you notice circular patches of balding spots, well, there is definitely, a problem, and treatment will be based upon the specific cause.

The following causes should be investigated if you are experiencing more-than-normal hair loss:

1. Diet: An unbalanced diet, especially one without enough protein, can cause temporary hair loss. Women who are anemic often experience loss.
2. Menopause: Because of the change in hormones during this period, hair loss can escalate, and, unfortunately, this can be permanent.
3. Frequent Shampooing: Shampoos contain a lathering ingredient called surfactant. This can be irritating to the scalp and cause itching and scratching, thus increased hair loss.
4. Improper Care: If you manipulate your hair too much, color and treat too much, blow dry and heat with curling irons and hot rollers too much, you will see increased hair loss.
5. Psychological/Physiological Stress: Increased hair loss can occur with pregnancies, major surgery, or a major life event, such as a death or divorce. These causes are temporary and hair growth will return to normal eventually.
6. Heredity: Heredity plays a part and comes from both sides of the family.
7. Other Health Conditions: Thyroid problems, lupus, and diabetes can accelerate hair loss. Obviously, these need to be diagnosed by a physician.
8. Alopecia Areata: This is an autoimmune condition characterized by circular patches of baldness. Basically, the body is attacking the hair follicles. Cortisone shots in the affected areas are required, and the earlier the better.
Take heart.
Hair products such as hot oil treatments and chemicals used for permanents can cause inflammation to the hair follicles which can also result in scarring and hair loss.

Some medications such as blood thinners, gout medication, birth control pills and too much vitamin A can cause sudden or abnormal hair loss as can following a crash diet, sudden hormonal changes, chemotherapy and radiation.
