Hair loss: Why it happens, and can it be stopped

The hairs of a protein called keratin are a small shaft. They are anchored in a group of specialized cells called hair follicles, which provide oxygen and nutrients for the root (or your bulb) of hair, and which design the substance with an oily substance called sebum.

The human body is completely covered with hair follicles, except on hands, feet and lips. Mostly, hair follicles are tiny, and the hairs they produce do not grow long.

Areas where hairs (and which appear above the skin) occur include the backbones, face, around the habitats, the back of the breast, the back, and most, of the scalp of the head. Usually there are about 100,000 hair follicles in the scalp.

The hair is in a continuous cycle of growth, relaxation and renewal. The hairs grow and then they are thrown, but as they grow at different rates they don’t lose at all.

It takes about three years to produce hair follicles that grow,  falls out and then varies, meaning that the scalp loses between 50 and 200 hairs per day.

When men start going bald

In some of the men, the hair growth process puts down.

The growth phase of each hair is gradually shorter, and the relaxation phase becomes longer. Eventually, the growing hairs become as short as they come from their hair vacuum.

The process starts on the head and patches on the crown, and expands from there. As the hair disappears, the patch goes more too.

This is called male pattern baldness, orrogenetic alopecia. It is the most common type of baldness, which affects about half of all men under 50 years of age and more than 80 percent under 70 years of age.

What about women?

Women also get pattern hair loss, but it is more common than men (although it is still the most common cause of hair loss in women).

The pattern of hair loss is different, however: it becomes thin over the top of the scalp rather than as a result of patch baldness, dermatologist.

“Often in women, it will affect 50 per cent of their hair, so many women will not go to the depression, but their hair can be so thin that it could be a big problem for them, ”says Associate Professor.

Over 50 percent of women have little hair loss as they grow older, and about 20 percent of women develop moderate or severe hair loss.

It’s nature, not nurture

Despite what people could say about washing and wearing a hair hat, patterned hair loss is due to genetic and hormonal factors.

The androgen hormones in our body (produced in different sizes by men and women) are thought to reduce hair follicles and stop them growing in people with genetic tendency.

Genes are the person who decides whether this happens to a particular person or not, at the age it starts.

Some genes are thought to determine how susceptible you are to losing your hair, and these can come from your mother and father.

“How these genes play determines what is happening in the passage,” says Professor.

“It’s not all phenomena or anything – it’s not like brown eyes or blue eyes. It’s a quantitative characteristic … so there’s the question that you go bald, but how many baldness will you get.”

Other causes of hair loss

Surrender to the hair only applies to genetics – there are a number of reasons why people may lose their hair.

Alopecia areata is an autoimmune condition in which one’s own immune system attacks the body’s hair follicles. It is often seen as one or more children, but in extreme cases it can affect their whole body.

Hair loss can be a consequence of some medications, medical treatments and illnesses. It can also occur after major surgery, stress periods, and people suddenly get shock. Hair loss in these cases is usually temporary but can be chronic.

Excessive hair (by focusing or drying) or treatments can create hair loss.

Hormonal changes or imbalances (which may occur during pregnancy or some medications) can cause hair loss.

Is there a cure?

In short: no. It is difficult to change age-related hairy recession.

“When you deal with people with hair loss, you can encourage a partial revival, but you are unlikely to get a full recovery,” says Professor.

While some people use products such as vitamin supplements or herbal remedies to tackle hair loss, there is no strong evidence to show these treatments.

There are, however, a number of treatments that may help to slow down or reduce hair loss, or encourage partial reconstruction.

“I try to prevent the action of [androgen] in the block, or try to encourage the hair,” says Associate Professor.

To block hormonal action and to help delay hair loss progress in men, a doctor or dermatologist may prescribe, one prescription medication designed to be taken once a day. Side effects of the drug are rare, but include driving reduced sex and sexual dysfunction.

When it comes to stimulating hair growth, a doctor or dermatologist may use minoxidil, lotion – to form a tablet – which has been used since the 1970s, and is available without prescription (and suitable for men and women).

Again, side effects are rare, but include scalp dryness, itching and dermatitis.

There are also some specific medications for women that inhibit the effect of androgen hormones, and helps to delay hair loss progress.

Whether a particular treatment is effective or not depends on a number of factors, including the amount of hair loss a person has.

“The longer he goes on, the more hairs will be lost back,” says Professor.

Apart from medical treatments, wigs and hair pieces can be viable cosmetic options for people with hair loss.

Hair transplant surgery

For people whose loss is too heavy for oral medicines or hair lotions, they may consider hair transplant surgery.

This is a procedure whereby a surgeon removes strips or hair plugs from the back or side of your head, and places them in areas where there is no hair, or between hairs in thinning areas.

The procedure may take several hours, and you may need some treatment sessions to get satisfactory results.

It can be expensive and there is a risk of difficulties, so – together with the treatment of hair loss – it is important to talk to a dermatologist or a family doctor first.
