Doctors have denied information about the effect of the sun on baldness
The question of the effect of the sun and heat on the condition of the hair is regularly discussed in the summer. Experts note that external factors can indeed affect the quality of hair and the condition of the scalp, but genetic predisposition and hormonal mechanisms still play a key role in the development of baldness. All the details are in the Izvestia article.
The real causes of alopecia
The main cause of male pattern baldness remains androgenetic alopecia, which is caused by heredity and the sensitivity of follicles to hormones. As explained by Maria Polner, a cosmetologist and dermatovenerologist at Olympus Clinic Sadovaya, the sensitivity of the bulbs to male sex hormones is responsible for thinning hair, not weather conditions.
Anna Ukrainskaya, an endocrinologist, nutritionist, and nutritionist at Olympus Clinic MARS, added that testosterone, under the influence of an enzyme, turns into dihydrotestosterone, which disrupts growth cycles. This process is embedded in the DNA and does not depend directly on the climate, although the external environment can become an additional negative factor.
The effect of the sun on follicles
According to Polner, solar radiation cannot cause baldness in a healthy person in one vacation, but it provokes oxidative stress. This supports the inflammation around the follicles and can accelerate the already started hair loss processes. The quality of hair also suffers from ultraviolet radiation: it becomes dry, brittle and dull.
"The scalp is also prone to burns, which is especially important for men with existing receding hairlines. Studies on cell cultures show that intense heat and radiation damage the DNA of matrix cells, but moderate urban heat alone does not lead to bulb death," the doctor said.
Seasonal hair loss and stress
Increased hair loss in late summer and early autumn is often associated with natural seasonal fluctuations in the growth cycle. This condition is temporary, and over time, the density is restored. However, severe thinning can be caused by iron deficiency, thyroid problems, or the effects of infections.
According to Anna Ukrainskaya, telogen effluvium is of particular importance — diffuse hair loss that occurs 2-3 months after severe physiological stress, high fever or serious illness. In such cases, the loss is reversible.
"In this case, the mechanism is completely different: the body shuts down functions that are not essential for survival, including hair growth. However, we emphasize that this is a temporary condition," the doctor noted.
Methods of prevention and treatment
Experts recommend using hats and special sunscreens for the scalp to protect your hair. If the problem has already manifested itself, modern cosmetology offers special methods that improve microcirculation and deliver nutrients directly to the follicles.
Maria Polner spoke about the mechanism of action of professional restorative procedures.
"Platelet growth factors stimulate the dermal papilla, prolong the hair growth phase and improve microcirculation in the follicle area," the dermatovenerologist said.
