This is how cortisol affects hair growth
Stress is omnipresent in our modern, fast-paced world. Whether it's professional challenges, private obligations or constant availability - our body reacts to it, especially by releasing the stress hormone cortisol. But how exactly does cortisol affect our hair growth? In this article we will shed light on why the stress hormone plays a central role in hair loss and what you can do about it.
What is cortisol?
Cortisol is a hormone produced in the adrenal cortex and plays a key role in our ability to cope with stress. It helps the body to deal with stressful situations by stimulating various functions in the body: it mobilizes energy reserves, influences blood sugar levels and at the same time suppresses inflammatory reactions.
In the short term, this hormonal response can be useful. But chronic stress and the associated long-term release of cortisol can have negative effects - especially on hair growth.
Cortisol and Hair Growth: The Connection
Hair growth occurs in cycles . In the so-called anagen phase, the hair grows actively, followed by a transition phase (catagen phase) and finally the resting phase (telogen phase), in which the hair falls out and new hair grows back.
Chronic stress and elevated cortisol levels can disrupt this natural cycle. How exactly? Researchers have found that cortisol forces hair follicles into an extended resting period, meaning hair growth stops. In extreme cases, this process can lead to increased hair loss, also known as telogen effluvium.
Another negative influence of cortisol is its effect on blood vessels. It reduces blood circulation in the scalp, which in turn affects the supply of nutrients to the hair follicles. Without an adequate supply of oxygen and nutrients, hair cannot grow healthily.
Hair loss due to stress: symptoms and treatments
Stress-related hair loss usually occurs evenly over the entire head and is manifested by an overall thinning of the hair. Unlike genetic hair loss, which primarily affects the hairline and the top of the head, stress-related hair loss causes hair loss over the entire head. Increased shedding when combing or showering can also be a sign.
When cortisol affects hair growth, it is important not only to take external action, but also to reduce stress. Here are some tips:
- Stress management: Relaxation exercises such as yoga, meditation or breathing techniques can help reduce stress levels.
- Balanced diet: Nutrients such as zinc , biotin and iron are essential for healthy hair growth.
- Healthy scalp: Good scalp care can help promote hair growth. Products that stimulate blood flow and nourish the follicles are ideal.
- Regular exercise: Sport not only helps to reduce stress, but also promotes blood circulation - and this has a positive effect on hair growth.
Conclusion
Cortisol is an essential hormone for our bodies, but in chronically high doses it can severely impair our hair growth. Anyone who is worried about their hair should not only pay attention to external factors such as care products, but also focus on internal causes such as dealing with stress. A holistic approach can help minimize hair loss and promote healthy, strong hair.
With the right measures and a conscious lifestyle, the negative influence of cortisol on hair growth can be successfully reduced.
