Human hair varies enormously.& Different people have hair that differs in color, in length, in diameter, and in its distribution on the body.

Types of hair
(2) kind of hair grow on the human body.
1-Vellus hairs
Vellus hairs are short hairs, only a centimetre or two long, and contain little or no pigment. The follicles that produce them do not have oil glands (often called sebaceous glands), and never produce any other kind of hairs Most women have vellus hair on their chest, and face. It can be darker and more noticeable in some women than others, especially those with darker complexions. Vellus hair helps the body maintain a steady temperature by providing some insulation

2-Terminal hairs
Terminal hairs are the long hairs that grow on the head and in many people on the body, arms and legs too. They are produced by follicles with sebaceous glands. In people who have inherited a tendency to baldness the hairs in these follicles gradually become thinner and shorter until they look like vellus hairs Terminal hair is there to provide cushioning and protection
**Lanugo hair
This is the hair that develops on an unborn baby

Hair Stucture
The chemistry of hair

Keratin is, the main constituent of hair(80%). is a remarkable protein which is resistant to wear and tear. It is the protein that makes up feathers, claws, nails and hoofs, as well as hair. Like other proteins, keratin has very large molecules made up of smaller units called amino acids, joined together in chains like beads on a string.
Hair also contains fats, pigment (melanin), small amounts of vitamins, and traces of zinc and other metals. Hair also contains water which, although it makes up only 10-13% of the hair, is extremely important for its physical and chemical properties .Hair is composed of strong structural protein called keratin. This is the same kind of protein that makes up the nails and the outer layer of skin

Each strand of hair consists of three layers.
1. An innermost layer or medulla which is only present in large thick hairs.
2. The middle layer known as the cortex. The cortex provides strength and both the color and the texture of hair.
3. The outermost layer is known as the cuticle. The cuticle is thin and colorless and serves as a protector of the cortex.

Structure of the hair root
• Below the surface of the skin is the hair root, which is enclosed within a hair follicle. At the base of the hair follicle is the dermal papilla. The dermal papilla is fed by the bloodstream which carries nourishment to produce new hair. The dermal papilla is very important to hair growth because it contains receptors for male hormones and androgens. Androgens regulates hair growth

The Hair Growth Cycle

Anagen Phase - Growth Phase
Approximately 85% of all hairs are in the growing phase at any one time. The Anagen phase or growth phase can vary from two to six years. Hair grows approximately 10cm per year and any individual hair is unlikely to grow more than one meter long.
Catagen Phase - transitional phase
At the end of the Anagen phase the hairs enters into a Catagen phase which lasts about one or two weeks, during the Catagen phase the hair follicle shrinks to about 1/6 of the normal length. The lower part is destroyed and the dermal papilla breaks away to rest below.
Telogen Phase - resting phase
The resting phase follows the catagen phase and normally lasts about 5-6 weeks. During this time the hair does not grow but stays attached to the follicle while the dermal papilla stays in a resting phase below. Approximately 10-15 percent of all hairs are in this phase at an one time.
At the end of the Telogen phase the hair follicle re-enters the Anagen phase. The dermal papilla and the base of the follicle join together again and a new hair begins to form. If the old hair has not already been shed the new hair pushes the old one out and the growth cycle starts all over again.

The regeneration of hair is influenc by many factors:

i. health
ii. hereditary factors
iii. diet
iv. hormone balance
v. age
vi. physical condition
vii. climate
viii. chemical effects
ix. sex
x. effects of disease

Reasons for removing hair

Medical reasons
In Ancient Egypt, many people depilated their entire bodies to prevent infestation by lice, fleas, and other parasites. Ancient Egyptian priests also shaved or depilated all over daily, so as to present a 'pure' body before the images of the gods.
Patients' body hair was once shaved before surgery for

reasons of hygiene

Social, cultural, or sexual reasons

For religious reasons Head-shaving is a part of some Buddhist, Christian, Muslim, Jain and Hindu traditions

In military institutions
Many military organizations also require males to maintain clean-shaven faces because facial hair can prevent an air-tight seal between the face and breathing or safety equipment, such as a pilot's oxygen mask, a diver's mask, or a soldier's gas mask

Hair removal methods

Hair removal describes any method of removing hair, especially from the human body.

Methods according to effected part

ü Depilation
affects the part of the hair above the surface of the skin. The most common form of depilation is shaving. Another popular option is the use of chemical depilatories, which work by breaking the disulfide bonds that link the protein chains that give hair its strength, making the hair disintegrate.

ü Epilation
removal of the entire hair, including the part below the skin and is therefore longer-lasting. Some individuals may use waxing, sugaring, epilation devices, lasers, threading, intense pulsed light or electrology. Hair is also sometimes removed by plucking with tweezers

Methods according to time
· Temporary
Depilation", or that, lasts several hours to several days and can be achieved by

1. Shaving or trimming

2. Depilatories

3. Friction

Epilation", or removal of the entire hair from the root, lasts several days to several weeks and can be achieved by

1. Plucking

2. Waxing

3. Sugaring

4. Threading

5. Burning off with hot wax can damage the cells and prevent hair from ever growing in the unwanted spot again.

6. Epilators
7. Prescription oral medications
8. Enzymes

· Permanent
Permanent hair removal involves several imperfect options. A number of methods have been developed that use chemicals, energy of varying types, or a combination to target the areas that regulate hair growth. Permanently destroying these areas while sparing surrounding tissue is a difficult challenge. Methods include:

1. Electrolysis
2. Laser
3. Intense Pulsed Light•

Temporary ways

1. Depilatories
How They Work: A depilatory is a cream or liquid that removes hair from the skin's surface. They work by reacting with the protein structure of the hair, so the hair dissolves and can be washed or wiped away.
How Long They Last: Several days to 2 weeks
Pros: Depilatories work quickly, are readily available at drugstores and grocery stores, and are inexpensive. They're best on the leg, underarm, and bikini areas; special formulations may be used on the face
Cons: Applying depilatories can be messy and many people dislike the odor. If you have sensitive skin, you might have an allergic reaction to the chemicals in the depilatory, which may cause a rash or inflammation. Depilatories may not be as effective on people with coarse hair.
be sure to apply the product only for the recommended amount of time for best results

2. Waxing

How It Works: A sticky wax is spread on the area of skin where the unwanted hair is growing. A cloth strip is then applied over the wax and quickly pulled off, taking the hair root and dead skin cells with it. The wax can be warmed or may be applied cold. Waxing can be done at a salon or at home.
How Long It Lasts: 3 to 6 weeks
Pros: Waxing leaves the area smooth and is long lasting. Waxing kits are readily available in drugstores and grocery stores. Hair regrowth looks lighter and less noticeable than it is after other methods of hair removal, such as shaving.
Cons: Many people say the biggest drawback to waxing is the discomfort: Because the treatment works by pulling hair out at the roots, it can sting a bit as the hair comes off
Professional waxing is more expensive than other hair removal methods
• Teens who use acne medications such as tretinoin and isotretinoin may want to skip waxing because those medicines make the skin more sensitive.
People with moles or skin irritation from sunburn should also avoid waxing.
Tips: For waxing to work, hair should be at least ¼ inch (about 6 millimeters) long. So skip shaving for a few weeks before waxing. Waxing works well on the legs, bikini area, and eyebrows

3. Shaving
How It Works: Using a razor, a person removes the tip of the hair shaft that has grown out through the skin. Some razors are completely disposable, some have a disposable blade, and some are electric. Guys often shave their faces, and women often shave their underarms, legs
How Long It Lasts: 1 to 3 days
Pros: Shaving is fairly inexpensive, and you can do it yourself. All you need is some warm water, a razor, and if you choose, shaving gel or cream.
Cons: Razor burn, bumps, nicks, cuts, and ingrown hairs are side effects of shaving. Ingrown hairs can happen with close, frequent shaving. When the hair begins to grow, it grows within the surrounding tissue rather than growing out of the follicle. The hair curls around and starts growing into the skin, irritating it.
Tips: You'll get a closer shave if you shave in the shower after your skin has been softened by warm water. Go slowly, pulling looser areas of skin taut before running the razor over them. Change razors often to avoid nicks. Using shaving cream may also help protect sensitive skin, like the skin around the genitals. If you’re nervous about cutting yourself, you can try an electric razor instead.
• Although most people shave in the opposite direction from the hair growth, if you want to avoid ingrown hairs it can help to shave in the direction the hair grow

Smile رد: طرق ازالة الشعر والحلاقة

1. Plucking
How It Works: Using tweezers, a person stretches the skin tightly, grips the hair close to the root, and pulls it out.
How Long It Lasts: 3 to 8 weeks
Pros: Plucking is time-consuming because you can only remove one hair at a time. However, it's inexpensive because all you need are tweezers.
Cons: Plucking can be painful, so it's best to do it only on small areas, such as the eyebrows, upper lip, and chin. If the hair breaks off below the skin, a person may get an ingrown hair. After plucking it notice temporary red bumps because the hair follicle is swollen and irritated.
Tips: Make sure you sterilize your tweezers with rubbing alcohol before and after use to reduce the chance of infection

2. Sugaring
(also known as Persian waxing) is a method of hair removal that has been in use for thousands of years.[citation needed] The process is similar to waxing. However, sugaring is supposed to be less painful because it only sticks to the hair (wax will also attach to the skin.) Nevertheless, as with other hair removal methods, there is some risk of skin irritation, sensitivity, or reaction. Though the process leaves a sticky mess, sugar is soluble in water and therefore sugaring involves a relatively easy cleanup with warm water.
• Sugaring paste is prepared with common household food items, such as sugar, lemon juice, honey or molasses.

3. Threading

is an ancient method of hair removal which originated in India, practiced in the Middle and Far East, and is now gaining popularity in Western countries. It is as popular with men in Arabic countries as it is with women, though men still shave the beard part of their face with a traditional safety or straight razor, doing their ears and eyebrows with thread. It is also popular in Persian culture, and is called Bande Abru ("Abru" means eyebrow, and "Band" is the thread). Threading the entire face is widely spread amongst Iranians, but it was originally practiced when a woman was getting marriedThin, twisted cotton threads are rolled over untidy hairlines, moustaches and so on, plucking the offending hair.
• Practitioners use a pure cotton thread. They generally twist the hair and threading pulls out a whole row of hair, as opposed to tweezing where only one single hair is pulled out. Threading is often preferred to tweezing because of the naturally straight lines of hair removed by the thread. It is pulled out from the follicle
• Like other methods of hair removal such as plucking or waxing, threading can result in skin irritation and ingrown hairs, however, hair re-growth becomes finer and more sparse after regular treatments[citation needed]. As the top layers of skin are not peeled or traumatized, threading is also recommended and an excellent option for those who have sensitive skin

4. epilator

is an electrical device used to remove hair by mechanically grasping multiple hairs simultaneously and pulling them out. The way in which epilators pull out hair is similar to waxing. Aside from the spring in early spring-type epilators, there are no parts in epilators that require regular replacement. Epilators come in corded, rechargeable and battery operated designs.
Epilation can be painful to some people because, as with waxing, it involves pulling hair out of the roots. Because of the pain involved being particularly bad on the first epilation of an area, some people prefer to have the area professionally waxed first, then use epilation to remove regrowthThe first type of epilator was the original Epilady, released in

5. Enzymes

(fx. the Epiladerm-Complex) that inhibit the development of new hair cells. Hair growth will become less and less until it finally stops; normal depilation/epilation will be performed until that time. Hair growth will return to normal if use of product discontinued. Products include the prescription drug Vaniqa (active ingredient eflornithine hydrochloride inhibiting the enzyme ornithine decarboxylase).

6. Prescription Treatments

A cream called eflornithine is available by prescription to treat facial hair growth in women. The cream is applied twice a day until the hair becomes softer and lighter — more like vellus hair. Side effects may include skin irritation and acne.
• Antiandrogen medications are another method that doctors prescribe to reduce the appearance of unwanted hair. Because androgen hormones can be responsible for hair growth in unwanted areas, these medications can reduce hair growth by blocking androgen production.
• Doctors often prescribe oral contraceptives in conjunction with these medications to enhance their effect, avoid pregnancy (since antiandrogens can be harmful to a developing fetus) and help regularize the menstrual cycle in girls who need it.
