Hair Loss caused by Stress – How are they connected?
Hair loss caused by stress may occur when psychological stress affects the normal function of hair follicles, leading to temporary or, in some cases, long-term hair loss. In recent years, scientific literature has increasingly supported the connection between stress and hair loss.
But what are the mechanisms through which stress contributes to hair shedding?
How does stress affect the scalp?
Beyond its clinical manifestations, scientific research has begun to explore the mechanisms through which stress affects the structure and function of the hair follicle:
- Increased cortisol levels, also known as the stress hormone, which can affect the lifespan and activity of scalp cells.
- Impaired microcirculation, leading to reduced delivery of oxygen and nutrients to the hair follicles.
- Inflammatory scalp conditions, creating a less favorable environment for new hair growth.
- Neuroendocrine imbalance, which indirectly affects both the quality of the hair and its growth rate.
Studies have shown that heightened nervous system activity triggered by stress can negatively impact the cells responsible for hair renewal, delaying the natural hair growth cycle.
Types of hair loss associated with stress
Based on clinical observations and evidence-based research, three main types of hair loss have been identified as being associated with psychological factors:
- Diffuse Telogen Effluvium
Stress can disrupt the normal hair growth cycle, causing a large number of hair follicles to prematurely enter the telogen (resting) phase. This results in increased hair shedding, usually occurring a few months after the stressful event.
- Trichotillomania
A compulsive disorder in which individuals pull hair from the scalp or other areas of the body, often as a coping mechanism to relieve stress, tension, or boredom.
- Alopecia areata
An autoimmune form of hair loss in which the immune system attacks the hair follicles. Although it is not caused exclusively by stress, psychological stress is recognized as a contributing factor that may trigger or exacerbate the condition.
Management of hair loss
Hair loss related to psychological factors is, in most cases, not permanent. By restoring psychological balance and supporting scalp health, it is often possible to achieve regrowth and restore normal hair density. Management is based on three key pillars:
- Stress management
Incorporating techniques such as deep breathing, meditation, physical exercise, or psychotherapeutic support can play a significant role in regulating stress levels.
- Scalp care
The use of gentle shampoos, avoidance of excessive heat exposure, and adequate skin hydration help maintain a healthy environment for the hair follicles.
- Medical or trichological follow-up
Depending on the severity and pattern of hair loss, treatments such as minoxidil, mesotherapy, low-level light therapy (Soft Laser), or specialized hair-strengthening protocols may be recommended.
