The Science of Stress and Hair Loss

Hi friends! I am back again to give you a gist on one of my favourite topics in Dermatology, hair loss, focusing on one aspect that dramatically causes it but not many know of and that is stress. Stress affects almost every aspect of our health, and our hair is no exception. When life gets hectic, and the levels of stress rise, one of the first places it shows is on your scalp. But what exactly is happening beneath the surface? Let’s dive into how stress can lead to hair loss and what you can do to protect your follicles. 

How Stress Impacts Hair Growth 

Your hair grows in cycles, consisting of three main phases: 

1. Anagen Phase (Growth Phase): This is when your hair is actively growing. It lasts for 2-7 years, depending on your genetics. 
2. Catagen Phase (Transition Phase): This short phase lasts about 2-3 weeks, during which hair growth slows down, and the follicle begins to shrink. 
3. Telogen Phase (Resting Phase): The hair rests for about 3 months before eventually shedding, making room for new growth.

In normal circumstances, about 85-90% of your hair is in the anagen phase, actively growing. However, when you’re under extreme stress, your body’s response can disrupt this balance. 

The Role of Stress Hormones 

When you experience stress, your body releases cortisol and other stress hormones. These hormones are mainly designed to help you deal with immediate threats by prioritizing essential functions like heart rate and energy supply. Unfortunately, hair growth is not considered an essential function of the body, so the body diverts resources away from your follicles. 

This shift then causes more hair follicles to enter the telogen phase prematurely, a condition known as telogen effluvium. This means your hair may stop growing and gets into a resting phase, which leads to increased shedding. One type of hair loss that is caused by stress is called 

Alopecia areata which is an autoimmune condition that leads to sudden patchy hair loss rather than gradual thinning. 

Signs of Stress-Induced Hair Loss 

If you’re noticing more hair falling out than usual, especially after periods of intense stress, you might be experiencing telogen effluvium. Some of the common signs are: 

Increased hair shedding, specifically during brushing or washing. 

Hair feeling thinner or less voluminous. 

Patches of thinning hair, though this is less common. 

Stress-induced hair loss usually appears 2-3 months after the stressful event, which makes it tricky to pinpoint the exact cause. 

How to Manage and Reverse Stress-Related Hair Loss 

But wait, I have good news! Stress-induced hair loss is usually temporary. Once the stress is managed, your hair growth cycle can return to normal. Here’s how you can support your hair: 

1. Stress Management: Introduce stress-reducing practices into your daily routine, such as meditation, deep-breathing exercises or Yoga. Getting enough sleep and regularly doing physical activities is also crucial. 
2. Nutrition: A balanced diet rich in vitamins and minerals, especially those that support hair health like biotin, iron, and zinc, can help nourish your follicles. 
3. Scalp Care: Gentle scalp massages can improve circulation and help create a healthy environment for hair growth. Avoid harsh hair treatments and opt for mild, nourishing products. 
4. Seek Professional Help: If you’re concerned about hair loss, a dermatologist can provide treatments like topical minoxidil or other therapies personalised to your exact concerns.

Stress will always be part of life, but understanding how it affects you can assist you in taking control of the situation. By managing your stress levels and caring for your scalp and hair, you can minimize its effects and keep your hair looking great. Remember, most stress-related hair loss is reversible, so with the right approach, you can regain your hair’s health and strength.
