Natural growth of hair

About 90% of the hair grows all the time, and the period required for hair growth may range from two to six years.

The remaining 10% of the hair, during that time, falls asleep for a period that may extend from two to three months, then this hair falls out with the end of the rest period.

When hair falls out, new hair from the follicles hair grows, starting a new growth cycle, from the beginning.

Head hair grows between 10 to 15 millimeters each month. However, as a person gets older, their hair growth begins to slow.

Mostly, the phenomenon of hair loss is due to the natural growth cycle of the hair. Falling at a frequency of 50 to 100 hairs per day is considered very natural.


Causes and risk factors for hair loss

Hair loss at a high rate can be caused by a large number of reasons.

In some cases of hair loss, new hair grows in place of the hair that fell out. In other cases, it is possible to successfully treat the phenomenon of falling by referring to a dermatologist.

As for the other cases, which do not have any treatment until today, many ongoing studies are being conducted, and it appears at first glance that optimism about the future and its implications can be seen.

However, it is worth talking to your dermatologist about the best and most effective hair loss treatment options for the eye condition.    

The most important causes of hair loss are summarized in:

1- The use of harmful chemical preparations

There are many women and men who use chemical preparations for hair care. Among these products:
Hair dyes
  • Colors and color-lightening materials
  • Hair straightening materials
  • Various materials used for creasing.
If these products are used according to the instructions, the possibility of damaging them with hair is very little.

However, if these products are used more often than not, the hair may be weak and tend to split (Trichorrhexis).

If the use of these preparations leads to weakening and fragmentation of hair, it is desirable to stop using them, until the hair is regenerated and recovered, and the damaged hairs disappear.
2- Hair loss and hereditary baldness
This phenomenon is known by its scientific name "Androgenetic alopecia / Calvities".

It is the most common cause of hair loss , as it is genetically transmitted from the mother or father.

Women who suffer from this phenomenon, their hair is usually very light and very little, but they do not develop Bald completely.

It is possible that this phenomenon may begin to appear in the second, third, and even fourth years of life.

3- macular alopecia areata 

It is not known what are the reasons that lead to the phenomenon of partial hair loss, known as " Alopecia Areata " (Alopecia Areata), but the prevailing belief is that it is linked to the problems affecting the immune system (as the body produces anti - self for his hair itself).

This phenomenon can occur in children or adults at any age.

People who suffer from it usually have a healthy general condition. But the injury is characterized by the emergence of bald areas, small and round, the diameter of which is equivalent to the diameter of a coin, or slightly larger.

Although alopecia areata is a very rare phenomenon, it may lead to the loss of all hair on the head and body, completely. In most cases, the hair returns to growth again, but treatment by a dermatologist will accelerate the regenerative process of hair.

4- Telogen Effluvium

Illness, stress or psychological tension , and other factors that may cause a large amount of hair to enter into the so-called "terminal phase" (the rest phase in the effectiveness of the follicular cells - Telogen) as part of the natural cycle of hair growth, which leads to hair loss at a pace High and accelerated (Effluvium), without resulting, mostly, completely bald spots.

In most cases, this type of hair loss stops automatically, after a few months.    

   Among the factors that cause crappy (chronic) hair loss:
  • Temperature high, severe acute pollution and influenza (Influenza) Acute
  • Complex surgery or chronic disease
  • Diseases of the thyroid gland (Thyroid gland)
  • Low protein feed
  • Iron deficiency in the blood
  • Take medications
  • Take birth control pills
  • Treatments for cancer
5- Ringworm of the head
Caused tinea capitis  (Tinea Capitis) for fungal contamination, caused by a skin fungus (Dermatophyte) and is characterized by the appearance of patches covered with dandruff (Dandruff) on the scalp (Scalp).

These spots get bigger, widen and spread and cause hair breakage, redness of the skin, puffiness, and sometimes even fluid from the scalp.

This disease is very infectious, and it is very common in children. This disease can be treated with medication.

6- Trichotillomania

This disease is characterized by the patient wrapping and bending hair, pulling and pulling it out, whether it is head hair, eyebrow hair or eyelashes (hair) in children, and sometimes in adults as well.

In some cases, this phenomenon is not only a bad habit, it disappears after obtaining professional advice and an explanation about the damage and side effects that can be caused by trichotillomania . But the phenomenon of trichotillomania may, in other cases, be an emotional reaction to stress or psychological stress, and sometimes it may be a serious and severe psychological disorder .

7- Scarring alopecia

 Cicatricial alopecia is a very rare phenomenon that causes bald spots accompanied by itching and / or pain.

The formation of inflammation around the hair follicles, causing damage and leading to the appearance of scars and hair loss, rather than growth.

The factor that causes alopecia areata is not known, but treatment is done by stopping the spread of inflammation and preventing its transmission to other parts and places of the scalp.

Diagnosis of hair loss

A correct diagnosis can help the majority of hair loss sufferers. As a dermatologist can examine the patient and diagnose the cause of hair loss and  baldness , then he knows whether this phenomenon will disappear on its own or whether there is a need to give the patient medication treatment.

Hair loss treatment

Hair loss treatments differ, and the most important of them are:

1- Hair surgery

Dermatologists and surgeons perform several types of surgeries aimed at restoring hair, restoring and restoring the places from which they fall, in addition to giving the hair a natural look, as possible.

The people who are most likely to undergo such surgeries, and who need them most, are those whose baldness appears most noticeable, who have very light hair and whose hair falls out due to scalp injury or as a result of burns .

The type of operation to restore hair is determined by the extent and shape of baldness. The dermatologist can recommend one of the below detailed types of surgeries, in order to get the best possible result.

2- Hair Transplantation

Hair transplantation depends on the "prevailing donation" principle (preferred), that is, taking hair from a healthy location and transplanting it, during the surgery, in order to grow again in the place affected by baldness. Hair transplantation requires the following:

  • Removing Streaks from the skin of the scalp: which contains hair from the back and sides of the scalp (these places are called "donation areas", since they contain hair that continues to grow for life).
  • Repair and restoration of the "donation area": a process that usually results in the appearance of a small scar, which is covered by the surrounding hair.
  • Cut scales from the skin of the scalp: which contains the hair, from the donation area, and divide them into groups of implants (implants) in order to transplant them into bald spots prepared for that.
The area that can be covered by hair transplantation varies depending on the size of the bald spot and the method of transplantation.

After about a month of the procedure, the bulk of the transplanted hair falls out. Two months later, new hair begins to grow, and then continues to grow at the normal pace. After six months, the transplanted hair will acquire a look and feel similar to that of the natural hair.    

3- Reducing the scalp

Shrinking the skin on the head is a solution for those who suffer from widening baldness.
This treatment is a surgical procedure during which the space of bald spots is narrowed and, in some cases, it is completely hidden, by removing some centimeters of hair-free skin, and then tightening the ends of the pieces toward each other and connecting them to the suture.
The scalp reduction process can be done on its own, or combined with another hair transplant.    

4- Scalp skin expansion / tissue tightening
Two devices are implanted under the skin of the scalp for three or four weeks.

The function of these two devices is to tighten the skin that holds the hair, in order to encourage and improve the results of surgery to shrink the skin of the scalp.

The tensioning device works with a technology similar to the elastic band, while the expansion device works like a balloon. They make it possible to reduce the amount of hair-free (bald) skin on the scalp.

When performing hair restoration, the person under treatment should expect:
  1. Anesthesia: Hair loss treatment is performed under local anesthesia , in a dermatologist’s office, in a private clinic, or even in the framework of a hospital.
  2. Daily activities: The ability to return to his daily routine activities, while refraining from undertaking major physical exertion or sporting activities until the doctor permits him to do so.
  3. Side effects: mild side effects appear, which may include: swelling and bruising around the eyes for two to three days (these side effects can be reduced by using ice packs and sleeping in a half-sitting position). In addition, the patient may lose sensation in the area from which the transplanted hair was taken, or in the area in which it was implanted. But this loss of sensation usually goes away within a period of no more than three months.
  4. Complex therapy: The treatment can be a combination of several medical procedures at different and different times, which means that the completion of treatment may require a long period of time that can last from a few months to a few years.
In all types of surgeries, there are always certain risks that may be part of this procedure. But post-treatment complications for hair restoration and repair are very rare.
