Crash dieting can lead to hair loss, a phenomenon known as telogen effluvium. This is caused by the body's reaction to a lack of nutrients, which can be triggered by sudden changes in diet and exercise. Restrictive diets that cut out food groups or severely limit calories can cause nutritional deficiencies, including a lack of iron, zinc, protein, selenium, and fatty acids, all of which are essential for hair growth. While hair loss from crash dieting is not permanent, it can be a warning sign of other health complications, such as anaemia, heart problems, and depression.

What You'll Learn
Nutritional deficiencies
The human body requires a range of nutrients, including proteins, irons, vitamins, and minerals, to support hair growth. A well-rounded diet that includes these nutrients is essential for maintaining healthy hair.
Deficiencies in specific nutrients, such as iron, zinc, protein, selenium, and essential fatty acids, have been linked to hair loss. Iron, in particular, plays a crucial role in hair growth, and an undersupply can trigger unexpected hair loss. Vegetarians and vegans, for example, may need to ensure adequate iron intake through alternative sources such as white beans, lentils, spinach, and soybeans.
Vitamin B12, riboflavin, folate, and biotin are also essential for healthy hair. A lack of these nutrients can contribute to hair loss. Additionally, a diet high in mercury, saturated fats, or processed sugar can negatively impact hair health, leading to increased shedding and thin, brittle strands.
It is important to note that while hair loss due to nutritional deficiencies is typically not permanent, seeking professional advice from a healthcare provider or dermatologist is recommended to address any underlying issues and receive personalized advice for hair regrowth.

Stress and exercise
While not all hair loss is caused by stress, it is often associated with hair loss. Chronic stress has long been linked to hair loss, and anxiety disorders like generalized anxiety, panic attacks, phobias, and OCD can trigger or worsen it. When we are stressed, we may adopt behaviors that help us find relief, such as hair pulling or trichotillomania, which can cause further stress due to body image issues.
Stress can cause a range of physical symptoms, including headaches, high blood pressure, an upset stomach, chest pain, and sleep problems, and it can also lead to emotional problems like depression, anxiety, and panic attacks. Research has shown that a major stress hormone puts hair follicle stem cells into an extended resting phase, halting hair growth while we continue to shed hair. This can result in Telogen Effluvium (TE), where there is a change in the number of hair follicles that are growing hair, leading to shedding and thinning of hair.
Exercise is a form of physical stress that can negatively impact the body if done excessively during stressful periods. It is recommended to reduce the intensity or frequency of workouts during such times to prevent additional stress on the body, which can contribute to hair loss. Regular exercise, when done in moderation, can help relieve stress, increase blood flow, and boost hair growth.
To manage stress-related hair loss, it is important to identify and address the sources of stress through self-care practices, therapy, medication, or lifestyle changes. This may include improving sleep, nutrition, and exercise habits, as well as incorporating stress-relieving activities such as scalp massages. While stress-related hair loss is typically not permanent, it is important to be patient as hair recovery can take time after the stress has been relieved.

Telogen effluvium
The excessive shedding associated with telogen effluvium occurs because hair follicles prematurely enter the resting phase and shed when they are supposed to grow. This can be triggered by a variety of factors, including stress, nutrient deficiencies, and weight loss. In the case of crash dieting, the restriction of certain foods can lead to nutrient deficiencies, which can then trigger telogen effluvium.
Hair loss due to telogen effluvium is usually not a cause for concern as it is often temporary and self-correcting. In most cases, the body adjusts within a few months, and hair regrows. However, it is important to address any nutrient deficiencies that may have resulted from the crash diet to prevent potential health complications.

Crash diets and hair regrowth
Crash dieting can lead to hair loss, a lesser-known side effect that can affect anyone. This type of hair loss is called telogen effluvium, which is characterised by excessive shedding and overall thinning of hair. It is triggered by nutritional deficiencies and stress, which are common side effects of crash dieting. Telogen effluvium is generally not harmful or permanent, and hair regrowth can be expected within a few months as the body adjusts.
Telogen effluvium occurs when hair follicles prematurely enter the resting phase and shed when they are supposed to grow. This can be caused by a lack of vital nutrients, such as proteins, irons, vitamins, and minerals, which are essential for hair growth. When the body doesn't receive the necessary nutrients, it responds by shedding hair at a faster rate. Additionally, severe calorie restriction can lead to malnutrition, which can further contribute to hair loss.
To promote hair regrowth after a crash diet, it is crucial to focus on a balanced diet rich in essential nutrients. This includes incorporating nutrient-dense foods such as nuts, eggs, spinach, cashews, legumes, meats, white beans, lentils, and soybeans, which are high in hair-healthy nutrients like iron, zinc, and protein. It is also important to address any underlying issues by consulting with a healthcare professional or dermatologist and incorporating supplements as needed.
In addition to nutritional deficiencies, crash dieting can also exacerbate hair loss for individuals with androgenic alopecia, commonly known as male or female pattern baldness. While a balanced diet is crucial for healthy hair, it is important to note that other factors, such as family history, genetics, stress, and medical conditions, can also influence hair growth and loss.
Overall, crash dieting can lead to temporary hair loss, but by adopting a balanced and nutritious diet, hair regrowth can be encouraged. It is important to be patient and committed to sustainable dietary habits and proper hair care to ensure long-term hair health and prevent future episodes of hair loss.

Alternative solutions
If you're experiencing hair loss due to crash dieting, there are several alternative solutions you can try:
- Focus on a balanced diet: Instead of following a restrictive crash diet, opt for a balanced diet that provides your body with the nutrients it needs. Include a variety of nutrient-dense foods from different food groups to ensure you're getting adequate nutrition for healthy hair growth.
- Address nutritional deficiencies: Crash diets often lead to nutrient deficiencies, such as iron, zinc, protein, and essential fatty acids. Correcting these deficiencies by incorporating nutrient-rich foods or supplements can help stop hair loss and promote hair regrowth.
- Manage stress levels: Restrictive dieting and rapid weight loss can cause stress, which is linked to hair loss. Find healthy ways to manage stress, such as moderate exercise, meditation, or other relaxation techniques.
- Seek professional help: Consult with a healthcare professional or dermatologist to address any underlying issues and receive personalized advice. They can help identify the cause of your hair loss and provide guidance on improving your diet and overall health.
- Consider alternative treatments: If dietary changes alone do not improve hair loss, consider treatments to stimulate hair growth. This could include topical solutions, prescription medications, laser therapy, or other recommended procedures.
- Prioritize overall health: Maintaining a healthy body weight and focusing on sustainable dietary habits are crucial. This not only reduces the risk of chronic diseases but also promotes long-term hair health and prevents future hair loss episodes.
Remember, hair loss due to crash dieting is usually temporary, and with patience and a commitment to a balanced, nutritious diet, you can promote hair regrowth and restore your full head of healthy hair.
