Beautiful hair is one of the most important sociological and psychological characteristics of every human being.
The hair follicle is renewed and grows every day. It is normal that we lose 50-100 hairs daily, in order for the hair follicle to start creating new hair. If the number of hairs that fall out per day is greater, it is necessary to pay attention and discover what is causing the increased hair loss.
What are the hair growth cycles?
Hair grows in cycles, and each hair follicle is independent in that cycle:
* The anagen phase is the phase of active hair growth, lasting for about 5 years
* The catagen phase is a short phase, lasting for a few days, when hair growth stops
* The telogen phase is the resting phase in which the hair falls out of the follicle, and it lasts for about 3 months
It is normal for about 85-90% of the hair on the scalp to be in the anagen phase, and about 10-15% of the hair in the telogen phase, when it eventually falls out.
What are the causes of hair loss?
The causes of hair loss can be different, and these are disorders within the body that affect the hair follicle. About 20% of people have seasonal hair loss, most often during September and October, which is caused by these hair growth cycles.
Physiologically, natural hair loss occurs after childbirth, when there is a drop in high levels of hormones that were maintained during pregnancy. A great amount of hair can fall out, but the condition always resolves entirely.
Increased hair loss is often caused by iron and ferritin deficiency in the body. After substitution therapy, hair loss stops and hair volume returns. Thyroid diseases, with hormonal disorders, whether it is thyroid hormone deficiency or thyroid hormone excess, strongly affect hair loss.
Lack of nutritional factors, especially protein due to rigorous diets, usually practiced by young girls, can cause irreversible hair loss. Also, the lack of trace elements, copper, zinc and others can contribute to hair loss.
Male-pattern hair loss is often seen in women with polycystic ovary syndrome (PCOS), caused by the effects of male hormones (androgens) – androgenic alopecia. Androgens affect the miniaturization of hair, which becomes thinner and thinner, giving the impression of significant thinning in the area above the temples and on the crown. If therapy is started on time, the process can be stopped and partially improved.
During menopause in women, also due to hormonal imbalance, hair loss and thinning may appear.
The intake of various medications can contribute to hair loss: beta-blockers, antihypertensives, oral contraceptives, retinoids, anticoagulants. Some chemotherapy drugs can cause complete baldness, almost always temporary.
Three months after big emotional stress or surgery and severe illness, the hair growth phase stops and it start falling out. After stressful situations have been eliminated, the hair completely recovers.
Constant hair tying, tightening the ponytail, brushing the hair too hard leads to mechanical damage to the follicles and hair loss.
How to prevent hair loss?
If your hair starts falling out more than usual and becomes thinner, it is necessary to contact a dermatologist.
With timely application of therapy, the process can be stopped, and the hair follicle can be stimulated to initiate growth.
Hormones, iron, trace elements, minerals are used in the therapy. It is necessary to treat the underlying disease.
Minoxidil 2% or 5% topical solution is prescribed, and shampoos are generally less effective.
