These days, we often meet men and women with sparse hair or total baldness, that no one can feel protected against hair loss. It can affect each of us, regardless of gender.
Hair loss causes are distinguished as Endogenous (internal) and Exogenous (external).
Endogenous causes – hormonal changes, autoimmune disorders, infectious diseases, feeding disorders; including vitamin deficiency, genetic predisposition, and disbacteriosis.
Exogenous causes – stress, physical, chemical, infections, radiological injuries of the scalp, physical overexertion, unfavorable ecological factors, and side effects of some medications.
Hair Loss Types:
There are 5 main types of hair loss; each requiring a specific treatment:
- Androgenic alopecia (male pattern)
- Temporary hair loss (female pattern)
- Focal alopecia
- Hair growth high frontal line
Androgenetic alopecia accounts for 95% of hair loss among men and 5% among women. Hair is affected by the derangement of renal metabolic processes, especially due to testosterone neutralization and secretion disturbance. During pubescence, when a considerable increase of the testosterone level is observed, the first signs of hair loss are detected by the age of 20 years old.
Temporary hair loss occurs among 95% of women. As opposed to the androgenetic type, temporary hair loss occurs in the top area while the frontal hairline is preserved. It is thought to be primarily conditioned by genetic predisposition, age, one’s endocrine system and hormone (androgen) quantity disorder.
Matter of Concern to Each 3rd Man
Alopecia among men is a condition of testosterone converting into dehydrotestosterone. This leads to hair papilla atrophy, spasm of hair root vessels and feeding disorder; resulting in hair loss which can occur at the ages of 30 and 60 years old.
Hair Loss Due to Thyroid Gland Function Disorder
Excessive hair loss (more than 60-100 hairs a day) can be the result of thyroid gland hyperfunction (hyperthyroidism) or hypofunction (hypothyroidism).
Anxiety, stress, emotional shock
Long lasting stress can also cause hair to fall out. Deep emotional and physical troubles can cause excessive hair loss even 2-3 months after the stressful event.
Women sometimes notice a temporary hair quality improvement during pregnancy. Hair becomes luxuriant because of increased estrogen levels during this period. However, 2-4 months after childbirth, the normalization of estrogen levels can lead to hair loss.
This type of baldness, which is conditioned by deep emotional experience, is characterized by different sizes of the bald foci. This is the result of a self-aggression. The organism seems to perceive the hairs as foreign particles and tries to get rid of them.
Female Hair Loss Resembling Male Baldness
This type of hair loss is a result of an increase of male hormones (the female body has a small amount of these hormones). The hair loss is found in women from 18-44 years of age. It does not lead to hair loss, instead hair becomes thin and the bald top becomes apparent. Parallel to this condition, seborrhea is often observed.
The gradual decrease in the production of female hormones, estrogen and progesterone, leads to a predomination of male hormone levels. The age of 50 for women is a crucial time. Stress and the psychological nature of menopause can often lead to hair loss.
Chemotherapy & Radiation Therapy
Chemotherapy causes hair follicle growth suspension. Once therapy is completed, the hair growth cycle is restored.
Radiation therapy, widely used in oncology, can lead to irreparable damage to the hair, especially in cases where radiation is directed at the scalp. This often damages the hair follicles causing an irrevocable alopecia.
