Hair Loss Anatomy


Hair is considered a troublesome affair for both sexes. Hair is formed inside the bulb by a complex bio- chemical method. The bulb gets the required energy and food from the blood circulation which carries basic substances which enter into the production of hair; just like fibre proteins (keratin), amino acids (cystine acid) and some other substance; such as Carbon, Magnesium, Calcium and Phosphate.

Hair is composed of two basic elements, which are:

The inner section or division of the skin root

The outer section of the skin stem, which is formed of hair shaft cells.
The inner section or division of the skin root; which is composed of hair roots cells; such as, hair follicle, hair papilla, hair bulb matrix with pigment cells, dermal papilla, cortex, outer root sheath, inner root sheath, hair follicle medulla, cuticle object and connective tissue.

The root is the centre of the growth of the hair. It is rich in veins and nerves. It has the characteristic of vacuolar encapsulation. This characteristic had been absent from most of the scientists and the hair research centres in the world. This is because they believed that when a human being looses his hair, and becomes bald, the hair bulbs die and so the hair does not grow once more.

This is a great scientific mistake, because the roots and bulbs of the hair, in case of their death- and there are thousands of the root cells- they may form a conducive atmosphere for bacteria multiplication. This causes the inflammation of the scalp by abscess, of about 80 to 100 abscess per day.

The hair has non- voluntary muscles, which are called the hair straightening muscles. They have a pivot angle which determines the direction of the growth of each hair in the scalp. They constrict when exposed to cold or fear: or when the adrenaline substance increases, this constriction causes the hair to stand up. So, it becomes straighter. The skin, in this case, shall be called the “goose skin”.


A sebaceous gland is connected to each hair; and which has a small duct. These glands are spread on the skin of the scalp, face, the opening of the anus, the opening of the mouth and the exterior ear. But; they are not found on the palm of the hand, nor on the bottom of the foot. If these glands are blocked, they form abscess. The sebaceous glands have an important role in the protection of the body from the poisonous materials; such as, the hair dye, which they absorb and excrete outside the body; especially in the scalp.


They also play an important role in the encapsulation and vacuolar stage when loosing the hair in the stage of baldness. This is done through filling the vacuum around the bulb which size would start to gradually contract, because of the weak blood flow and basic substances to inside of the bulb. Hair is divided into
six types: soft; very soft; thick, very thick, rough and very rough. The colour of the hair depends on the quantity of the colouring material, which is known as (melanin cells).

There are about 16 hair colours; as follows:

1- The dark, blackish dark and very blackish dark.
2- Brown, dark brown and very dark brown.
3- White, pure white, grey and leaden.
4- Golden, pale golden, dark golden.
5- Red, pale red, dark red.

Hair covers most of the parts of the human body, except a few parts. Hair varies in its length, colour and thickness, and amongst the various races of humans.

For example:
– The white race is distinguished by the density and softness, especially in the scalp (around 150,000- 160,000 hairs.)
– The Asians, Arabs and Latin Americans: they are distinguished by the thickness and softness of the hair, especially on the scalp (about 120,000-140,000 hairs.)
– The Africans hair: It is scarce, rough and thick, especially in the scalp (about 60,000 to 100,000 hairs).

Hairs grows in varying ways in the part of the body, or in a successive way (about 2 to 3% in the month on the scalp.)

It grows in helical way inside the bulb matrix. But; the outer root sheath grows progressively, some times, with noticeable length and thickness; such as, the scalp hair, the eye-brows, the moustache, beard, in the axilla, pubic hair and kneader area. The natural growth of the hair varies from a race to the other; and from a part of human body to the other.

The endocrine glands play an important role in the distribution of hair in the body, for example:
(a) The hair of the white man grows from 1 to 2 cm per month.
(b) The hair of the Asian, Arab and Latin American man grows from 0.5-1 cm per month.
(c) The hair of the African man grows from 0.5 to 1 cm per month.

The distribution of hair is different in women than in men. Hair grows in a man’s chest, stomach and neck; and also in the limbs.

In females, hair grows during the period of pregnancy, as from the 4th month. The fluffy hair covers the surface of the whole body in the remaining period of pregnancy. Then it starts to fall after delivery, from all the parts of the body, with the exception of the scalp. Such hair is usually soft to touch; then it falls after delivery, in a period of one to three months. Then it enters in the normal growth phases which take from four to seven years. These are three phases:-

1- The Anagen phase; which continues for 30 months with the white people, 36 months with the Asians, Arabs and the people of Latin America and 60 months with the Africans.
2- The Catagen phase; which continues for 12 months with white people, 9 months with the Asians, Arabs and Latin Americans and 30 months with the Africans.
3- The Telogen phase; which continues for about 12 months with the white people, 9 months with the Asians, Arabs and the Latin Americans and 3 months with the Africans.

These three phases occur successively. This is the opposite with animals where all hair take one phase of growth. Sometimes, all the hair falls at once from all parts of the body every three years.

The Natural Hair Fall:
The natural hair falls out in the Telogen phase:
1- For the whites; between 80-100 hairs per day.
2- For the Asians and Arabs; from 60-80 hairs per day.
3- For the Africans; between 10-20 hairs per day.
Cause of the Hair fall:
There are several causes for the fall out of hair. Some are external and others are internal causes:-
(a) External (natural) causes:

1- The much uses of the head cover (Taqiya), head cap (Beret) and (Qatra). These press on the scalp and the hair. With women, it is the tight scalf which presses on the front muscle of the scalp, and this assists in hair fall. The result is the pressure on the scalp, and accordingly on the blood capillary tubes. This decreases the quantity of the nutrition going into the bulb and weakens the growth of the hair. In this case, the bulb would be in a state of relative standstill (sleepy).
2- Pulling hair during thinking.
3- Period of pregnancy.
4- Period of lactation.
5- When undergoing medical surgeries and full or partial anesthesia.
6- The much fatty excretions on the scalp which prevents the natural ventilation of the scalp.

This is considered a conducive atmosphere for the multiplication of bacteria and fungi. This obstructs the natural growth of hair.

Histology of the skin

The skin is formed of an outer epidermis or cuticle; and an inner dermis or leather. Hair follicles penetrate the epidermis and have their bulbs deeply buried into the dermis. Attached to the hair follicle are sebaceous glands with their ducts opening into the follicle, sweat glands open into the epidermis.

The Natural Hair

The type of skin is divided into 4 parts: dry; oily; moderate and mixed. In the case of the natural fall out, the hair could return to its natural state gradually; without treatment.

Internal (natural) causes for hair loss

(a) Hemoglobin deficiency in the blood (anemia).
(b) The excessive menstruation.
(c) Use of contraceptives.
(d) Treatment by hormones (such as, those used for strengthening muscles).
(e) The diabetes disease (which slows the rate of growth of hair by about 40%).
(f) Deep thinking which consume high energy and reduces the quantity of glucose and oxygen in the blood.

This blood feeds the brain cells and results in the deficiency of the amount of energy which is required for feeding the front muscle which contains thousands of hair bulbs. This weakens growth and leads to hair fall and then baldness.

Anatomy of blood supply of the scalp

The skin of the scalp is thin skin. It contains hair, sebaceous glands. Hence the scalp is the commonest site for sebaceous cysts; sweat glands erector pile muscles and, of course, vessels and nerves.
The optical (or eye) artery feeds the front muscle of the forehead, after passing from inside the brain.

External causes (non-natural)

1. Excessive use of soap and shampoos which contain chemical materials; specially sodium hydroxide, potassium hydroxide and lead to capsulation, and vacuolar encapsulation.
2. The much use of swimming pools which contain chemical substances; such as, chlorine.
3. The mush use of chemical dyes, leads to the weakness of the ratio of melamine in the scalp.
4. The much use of hair creams has very harmful effect on the scalp. This is because creams for hair dressing contain alkaline chemical compounds of the derivatives of sodium salts. This leads to the weakness of the ratio of keratin in the scalp; which is the main source of the production of hair. This results in the weakness of the ionic links between parts of the hair, heavily. The impact may be, on the long-terms level, which may lead to local baldness.
5. keratins are the major protein components of hair, wool, nails, horn hoofs, and Quills of leathers.

These proteins generally contain large quantities of the sulfur containing amino acids, particularly cysteine. The helical keratin molecules twist around each other to form elongated strands called intermediate filaments.

The formation of a covalent chemical bond called disulfide bridge between the sulfur atoms on two cysteins on separate polypeptide chains of deratins allows for the cross chains and results in a fairly rigid aggregate. This phenomenon is seen to be consistent with the physiological role of the keratins, which provide a tough, fibrous matrix for the tissues in which they are found.

Human hair is approximately 14% cystine (cysteins cross-linked by disulfide brides)

6. The much use of oil baths.
7. The much use of the hair-drier at the coiffeur.
8. In the case of exposure to radiation or the chemical therapy.
9. Undulation of the hair: This is done by applying some acidic chemical substances on the hair; such as, the Theoglycolic acid which disintegrates the links amongst the parts of the hair; (These links make the hair hold together; preserve its strength, solidity and shape. This causes the hair to be curly and an oxidizing substance is applied to it, while the method of separation and its undulation does not only lead to the fall out of the hair, it also harms the scalp.

This cause harm to it, as a result of applying dyes and chemicals: In fact, there is a lot of exaggeration in the change of the colour of the hair with some ladies. Some of these dyes are only very harmful poisons and they may cause cancer.

An example is the paraffin line Dycine, (which is called in Sudan ‘the stone dye’ and which the Sudanese women mix with the ‘Hinna’. There are several cases- some of which are criminal and others are not criminal which resulted from the misuse of this type of dye. The disease of this type of dye is well known to everybody. Another hazard is leaving the remainder of the dye, negligibly, in pots, which are handy to children. This causes poisoning to children, indirectly. The dyes and their use, cause kidney failure to the individual, on the long-term. Also, it is known that some hair dyes contain thelium substance; (which is used for poisoning mice and may cause nervous tension.)

– The environmental pollution: The increase of the ratio of led and carbon mono-oxide in the atmosphere, especially with the inhabitants of the crowded towns.
– The much use of the hair drier (Estishoir) leads to breaking the hair, irritation of the scalp and the increase of the dandruff.
– Pulling the hair in some combing models; such as, (the cake and the horse tail), leads to the hair fall out, rather lightly, in the direction of the growth of the hair, sometimes. Therefore, it is advised to tie the hair in a light way in the direction of the growth of the hair itself. For washing the hair, Senhoryol shampoo shall be used.
– The non-use of the sharp hair brush, which injures the scalp. So, it is advisable to use the brush and the comb with the ball ends and the SAN COMB.

The Dandruff

Dandruff is a common problem. They are fatty-dry excretions which multiply by the irritation of the skin; and with certain persons of those with the fatty skin. Fear, anxiety, concern, grief and depression are psychological factors which increase these fatty excretions. Removing of these excretion had become easy with the use of Hair Control.
