Many women are concerned that excessive hair loss can have different origins. Unlike what common sense may indicate, the problem is not about poor circulation, clogged follicles or excessive hair washing. The causes usually have a much more complex origin. Genetic factors, hormonal changes, stress, inadequate nutrition, and even excessive chemistry are some of the examples that lead to an alteration of the normal hair cycle.
One of the most common causes is female androgenetic alopecia – popularly called baldness . As the name says, it is a genetic disease that has the characteristic of the progressive thinning of the threads that, at a certain moment, stop growing completely.
8 mistakes that end the health and beauty of hair
The problem is due to the hypersensitivity of scalp receptors to androgen hormones, such as testosterone. “Normally, women produce small amounts of this hormone, but after 40 years of age, there may be a significant increase in its production, leading to the onset of the condition. Or, in other cases, they may be exposed to hyperandrogenism (male hormone increase), also contributing to the development of the condition ”, explains dermatologist Anderson Zei Damasceno, from Clínica Visia.
There are also certain dermatological diseases that result in a similar scenario. “This is the case with alopecia areata, an autoimmune condition that attacks the hair follicle, destroying it. It is characterized by the loss of hair in round or oval areas of the scalp, reaching its total loss ”, explains the doctor.
In addition, irritative, inflammatory or infectious scalp processes may trigger the hair loss process. “Thus, the excess of chemicals, dyes, dryers and traumas will result in greater hair loss”, says the expert. According to him, stress is another factor that influences. “In this context, the person releases chemical mediating substances that alter hormonal cycles, leading or triggering capillary loss”, he explains. “A diet low in vitamins and nutrients can also compromise the health of the hair. This is the case of the lack of iron and vitamin A in the body ”.
Treatment requires detailed investigation
Today, there are countless possibilities. Capillary laser treatments, application of medicines on the scalp (drug delivery) with microneedling or laser, use of topical medicines, dietary reeducation and hair transplantation are some of the procedures available. But, first of all, it is necessary to make a diagnosis and identify the real cause of the problem.
The tricoscopia , a simple, noninvasive test, observe the situation of the wires and scalp, using a super – powerful zoom that increases up to 70 times the size of capillary structures. According to the doctor, only then is it possible to diagnose the disorders and direct the best treatment.
