Despite being more common in men, androgenetic alopecia affects about 5% of the female population in Brazil. But the good news is that the disease, which causes hair loss, can be controlled through topical and oral medications and home use of LEDs that help with hair growth.
“Characterized by partial or complete loss of hair, androgenetic alopecia, which is more frequent in men due to the greater amount of testosterone circulating in the body, has the same causes in both genders, being mainly linked to genetic and hormonal factors, especially sensitivity to testosterone, the male sex hormone, ”explains Dr. Flávia Betini, a dermatologist member of the Brazilian Society of Dermatology and the American Academy of Dermatology.
While in men, androgenetic alopecia generally affects only the
front and the crown of the scalp, sparing the lateral and
posterior areas , in women there is a diffuse rarefaction of hair, with
flaws in some regions, and the hairs also become thinner – although they rarely reach full baldness. “Unlike the male condition, in which baldness starts at the frontal line, ascending to the parietal region, with the formation of entrances and the patient loses hair and exposes the friar’s crown, the woman has a frontal rarefaction, but mainly in the line capillary mean.
If we streak in half, we will see a diffuse rarefaction where the scalp begins to become evident throughout this region. Then the hair implantation line goes up, getting taller, and the hair gets thinner, thinner in the entire region of the central scalp area from the midline towards the sides ”, details the dermatologist Dr. Claudia Marçal, member of the Brazilian Society of Dermatology and the American Academy of Dermatology.
This problem can be identified when the daily amount of falling hair is greater than 100, since they are not yet fully grown and are smaller than those left in the head. “In addition to hair loss, in androgenetic alopecia there is atrophy of hair follicles and miniaturization of hair, which over time does not grow more than one hair”, says dermatologist Dr. Flávia.
As this is a problem of genetic pattern, dermatologist Dr. Claudia Marçal advises that, when a female patient knows she has a history of genetic baldness, she should see a dermatologist or trichologist. “She should start to worry, since post-puberty,
usually the most aggressive and most acute cases start at the stage
when the girl enters menarche, has her first menstruation and there is a change in the quality of the hair, which will getting thinner, more miniaturized, with growth deficiency, with a picture where she perceives a constant fall ”, she says.
According to doctor Dr. Flávia Betini, because it is directly linked to
hereditary factors, androgenetic alopecia cannot be prevented, but it is possible to delay and control the condition through supplementation, lasers sessions and the use of oral medications, as hormone blockers, and topicals, like Minoxidil. “As for the treatment, it can vary according to the severity of the hair loss, which may include the supplementation of multivitamins, trace elements and growth factors and the use of vasodilator drugs, antiandrogens, contraceptives and dihydrotestosterone inhibitors”, completes the Dr. Flávia.
In addition, microneedling sessions can be done on the scalp followed by the application of medications such as Minoxidil and, in more severe cases, it is also possible to opt for a hair transplant. However, it is necessary to understand that the disease has no definitive cure, so the treatment must be continuous and
with a regulated care routine so that there is a significant improvement.
In addition to the methods mentioned above, it is also possible to use, both for
treatment and to delay the onset of the condition, home use equipment based on photobiomodulation, such as the Capellux I9 from Cosmedical, which has the ability to transform the light energy of LEDs in physiological effect, with each wavelength acting on specific chromophores (targets) and generating therapeutic responses.
“The equipment stimulates stem cells and the production of growth factors and promotes vasodilation in the hair veins that irrigate the hair follicle, consequently increasing the ATP (energy) production of the cells. With this, the device stimulates the appearance of new hair in the follicles that have not yet atrophied, in addition to reducing the amount of hair that falls out daily, ”says Dr. Flávia. As for the mode of use, the Capellux i9 helmet must be worn every day for seven minutes.
