Hair Loss Factoids

• It is normal to lose 50-100 hairs from the head each day
• Each hair on the head grows for about 3-5 years before being shed
• 30 million women suffer from hair loss
• Scalp hair grows at a rate of about 1 cm (just under 1/2 an inch) a month
• We each have about 100,000 hairs on the scalp
• In the United States, there has not been an elected bald President since the television age began.

How Hair Grows

The portion of the hair that we can see is called the shaft. Each shaft of hair protrudes from its follicle, which is a tube-like pouch just below the surface of the skin. The hair is attached to the base of the follicle by the hair root, which is where the hair actually grows and where it is nourished by blood capillaries. Like the rest of the body, hairs are made of cells. As new cells form at its root, the hair is gradually pushed further and further out of the follicle. The cells at the base of each hair are close to the blood capillaries and are living.

As they get pushed further away from the base of the follicle they no longer have any nourishment, and so they die. As they die, they are transformed into a hard protein called keratin. Each hair we see above the skin is dead protein. It is the follicle, which lies deep in the skin, that is essential in growing hair. The thickness of each hair depends on the size of the follicle from which it is growing.

Hair growth is not a continuous process, it has several stages:

• ANAGEN PHASE. The first phase is the growing stage. Hair grows at about 1 cm each month, and this phase lasts between 2 and 5 years.
• CATAGEN PHASE. As this phase begins the bulb detaches from the blood supply and the hair shaft is pushed up.
• TELOGEN PHASE. This is followed by a resting stage, during which there is no growth. This phase lasts about 5 months.
• At the end of the resting phase, the hair is shed, and the follicle starts to grow a new one.
• At any moment, about 90% of the hair follicles of the scalp are growing hairs in the first phase; only about 10% are in the resting phase.
• If a follicle is destroyed for any reason, no new hair will grow from it.

How Baldness Occurs

If any hair growth stage is disrupted, the individual may become bald. For example, if follicles shut down (meaning that they stay in the resting phase, and then shed the hair) instead of growing new hairs, there will be less hair on the head. Another reason might be interference with root formation in new hair cells, during the growing phase. If follicles have been destroyed (ie., a burn, loss of layered skin or trauma), there will be baldness in that area. An individual can also look bald if the hairs are growing but are so fragile that they break just as they emerge from the follicle.

Recently, scientists at Columbia University in New York announced the discovery of a gene that appears to be the 'master switch' for hair growth. They found the gene after comparing the genes of hairless mice belonging to a mutant breed, and comparing the genes of 11 members of a family who had lost all their hair. This discovery is a step towards understanding how the hair follicle works and how baldness happens. This may lead to effective treatments becoming available in the future.

Female Pattern Baldness

For women, thinning hair can occur throughout the entire scalp or in random patterns. In many cases, hormonal changes and age will cause thinning over the entire scalp while certain genetic conditions and medical treatments can result in spotty or total hair loss. For these cases, Hair Club may incorporate several technologies to achieve a desired result.

The Hormonal Factor:

Dihydrotestosterone (DHT), a derivative of the male hormone testosterone, is the main culprit of female hair loss.  Hair follicles in areas that are destined to become bald seem to be especially sensitive to DHT and shrink when exposed to it.

Knowing that each case of hair loss is unique, Hair Club has made several options available to help both men and women with thinning hair.

Hair Loss: True or False?

Brushing the hair 100 times a day will stimulate the circulation and prevent hair loss
» False
Vigorous brushing is more likely to injure the hairs and make the problem worse.

Some hairstyles, like braiding can cause hair loss
» True
Styles that pull or put tension on the hairs - such as tight ponytails or corn-rows - can cause hair loss.

Hats encourage hair loss because the hair can't breathe
» False
Hair does not need to breathe. Only the root of the hair is alive, and this gets its oxygen from the blood in the scalp.

Frequent shampooing makes hair fall out
» False
The 50-100 hairs we lose each day often become tangled with the rest of the hair but are washed out when we shampoo. So we see what seems like a lot of hair in the shower after shampooing, but in reality these hairs have been shed earlier.

Blow-drying can worsen hair loss
» True
The reason is that extreme heat damages the proteins in the hairs making them fragile and liable to break off. Brushing the hair during blow-drying causes more damage. If you use a hair dryer, it should be set on the coolest setting.

Hair coloring, perm solutions and hairsprays worsen hair loss
» False
Hair dyes, perms and hairsprays do not affect thinning hair. Perms and hairsprays can help to disguise the problem. Remember, it is the follicle, which is located beneath the skin, that produces the hair. Chemical treatments can damage the hair strands but can't affect the follicle.

Baldness can be linked to heart attacks
» Inconclusive
In 1999, doctors at Harvard Medical School found that men who had lost hair at the crown of the head had a 32% increased chance of coronary heart disease. Hair loss at the front of the head hardly increased the risk at all. Regardless of how accurate this study could be, to promote a healthy lifestyle, you should stop smoking, eat healthy, have your blood pressure checked and do some exercise.

Suggestions

• Wash your hair daily with a mild shampoo. Dirty hair lies flatter and looks more sparse.
• Avoid anything that could make the hairs liable to break. After washing don't rub your hair vigorously or use a hot hairdryer. Rather, pat the hair dry with a soft towel or use a low setting on the dryer or, even better, let it dry naturally. Use a brush with soft bristles. Use a creame rinse detangler to undo any tangles, rather than pulling with a comb.
• Protect bald areas from sun damage. Maxxam Hair Styling Products with sunscreen have been specially prepared for this purpose, and is available from Hair Club Centers. It is non-scented and non-greasy.
