Hair health doesn't exist in isolation. Your stress levels, sleep quality, exercise habits, and mental state all influence your follicles. Understanding these connections helps you optimize from multiple angles.
Stress and Hair: The Science
Chronic stress elevates cortisol, which can push hair follicles into the telogen (resting) phase prematurely. This manifests as telogen effluvium—diffuse shedding that occurs 2-3 months after a stressful period. While different from pattern hair loss, stress can accelerate existing androgenetic alopecia.
The Feedback Loop: Hair loss causes stress. Stress worsens hair loss. Breaking this cycle requires addressing both the physical treatment and the psychological response.
Sleep and Growth Hormone
Most growth hormone is released during deep sleep. Growth hormone supports cellular regeneration, including hair follicle function. Poor sleep quality may impair your body's ability to maintain healthy hair growth cycles.
Exercise: The Balance
Moderate exercise improves circulation, reduces stress, and supports overall health—all good for hair. However, extreme endurance exercise or overtraining can elevate cortisol chronically, potentially working against you.
The Integrated Approach
- Treat the physical: Evidence-based medical treatments
- Manage stress: Meditation, therapy, or lifestyle adjustments
- Prioritize sleep: 7-9 hours of quality rest
- Move regularly: Moderate exercise most days
- Reframe mindset: Progress over perfection
