A permanent wave process inexpertly applied is probably the most damaging chemical treatment that hairdressers see. The cuticle scales on the hair is lifted up and separated from each other. They will never return to normal, and as soon as a comb passes over them they may break off. The cuticle may be completely stripped off, revealing the cortex underneath. This too is now exposed to weathering, and will probably not survive unbroken for long.

From straightforward styling to elaborate perms, from a temporary tint to a platinum bleach, all these processes depend on changing part of the structure of hair. The stylists and technicians who have to apply them are expected to have a thorough understanding of hair structure, the hair growth cycle and the continuing care of hair. They need a working knowledge of the disorders of the hair and scalp, the chemistry of hair care products and the ways in which they protect the hair, and the science that underlies the various cosmetic procedures.

Just as a doctor takes a 'history' of a new patient in the surgery, so the stylist looks at the history of a client's hiar and examines its condition, in particular whether there is evidence that it has been chemically treated previously. The doctor can only decide what can be done for the patient once that history is known and understood: in the same way, the most expert stylist can only decide what is or is not possible after that examination has been made.

Styling hair means temporarily or permanently altering its shape. Setting is different from perming in that there is no chemical reaction in the hair. All that happens is that some of the weak hydrogen bonds are broken by water and then re-form in the newly positioned hair as the water evaporates.

A curl can be produced by setting hair on a former such as a curler or roller - that is, allowing wet hair to dry while twisted round the former. (Fixing wet hair into pin curls has a similar effect.) After the curlers or rollers have been removed the hair holds its shape until it gets wet again.

In a perfect world, the hair could be left to dry naturally on the curlers or rollers and then combed out with a broad-toothed comb. But the pace and hurry of modern life makes this a luxury that we cannot afford, and the hair dryer has to be used to speed the process up. Heat is a great enemy to hair, however, and that means that dryers must always be used with great care and on a moderate setting.

Curls produced by setting are tight when they are first formed, but they can be brushed out into a lighter style. Using setting lotions or hair sprays gives a firmer effect, and helps to hold the temporary curl in for longer.

Softer, looser styles can be created by brushing and blow drying only, without using rollers. The principle is exactly the same as that of the setting process. The only difference is that the hydrogen bonds re-connect to form the style that has been shaped by the brush.

All hair gradually absorbs moisture from the air, and as the hydrogen bonds break it will in time lose its style - especially in damp weather!

The Perm
The strong disulphide linkages in hair are formed when the hair cells harden into keratin in the hair follicle. These are the bonds that keep the hair shaft in shape. In order to change its shape, the disulphide bonds have to be broken down and re-formed into a different pattern. We saw that changes to hydrogen bonds in the setting process are only temporary. Chemical changes to the disulphide bonds are permanent (hence, the PERM).

People have been trying to turn straight hair into waves and curls for thousands of years. The women of Ancient Egypt used to apply a mixture of soil and water to their hair, wrap it on crudely made wooden 'rollers' and then bake the muddy mess in the sun - the results would have been anything but permanent, however! In fact, as we have seen, temporary waving is still carried out by setting damp or wet hair into a new shape on curlers or rollers. Heat from a dryer and the use of a setting lotion give a firmer, longer-lasting style. But the changes to the hair are the same as the Egyptian ladies brought about: only the weak hydrogen bonds in the hair are affected, and the hair goes back to its original shape as soon as it is dampened.

The first truly permanent waves became available in 1920. The waving lotion was activated by heat from an electrical device. The early models did not have thermostats, and it was difficult to control their temperature.

Early in the 1940s the 'cold wave' was introduced. This was basically the perming process that we use today. The cold wave had many advantages: the unpleasant heat and weight of the old appliances were completely eliminated, and the hair could be waved closer to the scalp.

Going bald is something that no one wants to deal with. Not withstanding Britney Spears stunt at the hairdresser - there are however, a lot of adults that do have to face this problem at some point in time. There may even be a few teens that have to face premature hair loss. There are many different reasons why hair begins to fall out and for some of these reasons, it is possible to control or fix the problem.

Stress and mental anguish often is the cause for temporary hair loss (or excessive hair fall) in women, both adults and teens. Social pressures, family crisis, other health conditions, etc may cause psychological stress that could manifest itself in hair loss.

When young people start to deal with hair loss, this is usually due to a sickness or not eating right. There are some medical conditions that like need to be treated and sometimes the treatment like chemotherapy for cancer can cause hair loss. A lot of young people do not know that wearing their hair in a certain style for a certain length of time can also cause the hair to be weakened and it may start to fall out.

When anyone looses his or her hair, this is going to be stressful. This is certainly stressful and can cause anyone to become depressed. This is the main reason why it is important to find out everything there is to know about hair loss so that it can be taken care of. The first thing to do is find out what is causing the problem so that the hair can start to grow back.

The hair is made up of the shaft, the root and the follicle from which the hair grows. Most people will loose from fifty to one hundred hairs a day. These hairs are replaced by hair that grows back. This kind of hair loss is completely normal and nothing for anyone to worry about. If you are loosing a larger amount of hair than this or if you are seeing balding spots on your head, this may be an indication that something is wrong.

If you are dealing with unusual hair loss, it may a good idea to talk to your physician. It may be something simple like the lack of a vitamin or using the wrong shampoo. It may also be something else that needs treatment. A doctor will be able to run the appropriate tests for hair loss to find out what is going on.

Once you get treatment for hair loss, you may find that it will take some time before you start to see replacement hair start to grow. The main thing is to be patient and maintain a healthy diet. Do the recommended treatments and try to avoid stressful situations. These are all things that can cause hair loss. You will find that it is possible to have beautiful hair once again.

Hair loss creates baldness. A bald person looks older than his real age. This abnormal hair loss is technically called alopecia. It does not affect our health directly but indirectly it creates problems, such as low self esteem. When alopecia occurs at a young age, it creates an inferiority complex that leads to other health problems.

There are many treatments; some are medications and some are surgeries. You need to find the best hair loss treatment by consulting a specialist. If the condition is not severe, then, you can stop the hair loss with medication or natural supplements such as whey protein or vitamins.

hair_loss_types : Types of hair loss and their causes posted by ena-oopi

Different types of hair loss are caused by different things. Here is a look at various types and their causes.

Androgenetic Alopecia: This is by far the leading type of hair loss in men and women and is a result of genetics. This genetic hair loss is hereditary and can be inherited from either side of the family. Commonly known as male and female pattern baldness, this type of hair loss is due to the action of a chemical known as dihydrotestosterone (DHT) which attacks the hair follicles and causes hair loss.

Telogen Effluvium: This condition is also referred to as diffuse hair loss. In this type of hair loss, a lot of hair is lost in a short span of time. Leading causes for this condition are pregnancy, chemotherapy for cancer treatment, very high fevers, severe illnesses, and sometimes even high levels of stress can result in telogen effluvium. This is not a permanent condition and most of the lost hair does grow back within a few months.

Alopecia Areata: Any sudden loss of hair resulting in bald patches is the condition of alopecia areata. This is an autoimmune disesase where the hair follicles are attacked by the body. Why it happens has not yet been discovered. It can be a mild case and result in bald patches on the head or if it is severe it can affect the entire body hair. This condition usually treats itself without any medication although some doctors may prescribe certain steroid injections for repeated occurrence of localized alopecia areata.

Traction Alpoecia: This type of hair loss occurs in people who routinely pull on their hair through harsh brushing or hairstyles such as a tight ponytail that pull on the hair. One prime example of this condition is the braided hair popular with African-americans.

Medication Related Hair Loss: Certain medicines such as accutane, allopurinol, and anti-thyroid medicines are known to cause hair loss.

Diet Related Hair Loss: Temporary hair loss and hair shedding can result from poor nutrition and an unbalanced diet. If your body is deficient in certain minerals, vitamins, and/or iron, it can cause you (or him or her) to lose hair.
