Far from being just an aesthetic issue, hair loss can indicate hormonal disorders.
This reality challenges the common notion that hair loss is just a natural process.
What is your body trying to communicate with this noticeable change? Understanding the underlying causes is the first step to finding a solution.
Understanding the Hair Cycle and Hormonal Influence
Hair has a fascinating life cycle, divided into three phases. The first, anagen, is the active growth phase.

Next comes the catagen, a period of transition. Finally, the telogen It is the resting phase, where the hair is released from the follicle.
What not everyone knows is that hormones are the conductors of this process.
They are responsible for regulating the timing and intensity of each phase. Hormonal imbalance can affect this orchestra.
A hormonal imbalance is like an out-of-tune conductor, altering the rhythm of the hair cycle.
This can cause the anagen phase to be shortened, leading to a greater number of hairs in the telogen phase and, consequently, accelerated hair loss.
The Main Hormones and Their Relationship to Hair Loss
The connection between hormones and hair loss is complex and multifaceted.
Several hormones may be involved. Androgens, such as dihydrotestosterone (DHT), play a crucial role.
Testosterone, through the enzyme 5-alpha reductase, is converted into DHT.
In genetically predisposed people, DHT can bind to receptors in hair follicles, leading to miniaturization and ultimately atrophy.
Other hormones, such as thyroid hormones, are also vital for hair health.

Hypothyroidism, for example, can cause a hair loss diffuse and noticeable, as low hormone production affects metabolism and cell growth.
Additionally, female sex hormones such as estrogen and progesterone also play a significant role.
During pregnancy, for example, the increase in these hormones prolongs the hair growth phase.
After childbirth, the sudden drop in hormone levels can lead to postpartum telogen effluvium, a temporary but intense hair loss.
Warning Signs: When Hair Loss Is a Concern
After all, how to differentiate one hair loss normal or something more serious? The main difference is in the consistency and quantity.
If hair loss becomes persistent, it is a sign that something may be wrong.

Androgenetic alopecia, popularly known as male or female pattern baldness, affects millions of people globally.
The Brazilian Society of Dermatology estimates that it affects 80% of men and 40% of women at some stage in their lives.
Hormonal Investigation and Accurate Diagnosis
If you suspect a hormonal problem, the best course of action is to seek out a specialist.
Only a dermatologist, endocrinologist, or general practitioner can perform a complete evaluation and order the necessary tests. hair loss should not be ignored.
The investigation usually includes blood tests to check levels of thyroid hormones, testosterone, prolactin, and others.
The doctor may also request a trichogram, which analyzes the condition of the hairs and follicles.

Without it, therapy may be futile, and the underlying problem will persist. Self-medication, for example, is dangerous and ineffective.
Imagine that hair health is like the foundation of a house.
If the foundation (hormonal balance) is compromised, the structure (your hair) will also be affected, no matter how well you care for the outside. You need to address the root of the problem.
Treatment Options and the Role of the Professional
Treatment for hormonal hair loss depends on the cause.
If the cause is hypothyroidism, hormone replacement therapy may be the solution.
In the case of PCOS, medications that control androgens are often prescribed.
Topical therapies, such as minoxidil, may also be indicated to stimulate follicle growth.
In other cases, the use of oral medications, such as finasteride, to inhibit the 5-alpha reductase enzyme, is common.
