What Is Anorexia Hair Loss And How Can You Treat It?

Anorexia-related hair loss is usually caused by severe nutritional deficiencies and hormonal disruption.
When the body lacks essential nutrients, hair growth is deprioritized, leading to diffuse shedding. In most cases, hair loss is reversible with nutritional rehabilitation, medical support, and sustained recovery.

What Is Anorexia Hair Loss?

Anorexia nervosa is a serious eating disorder marked by extreme calorie restriction and significant weight loss. One of its physical consequences is hair loss, which can be emotionally distressing and visible.

Hair loss linked to anorexia is not a separate condition but a physical response to prolonged malnutrition. It reflects the body’s attempt to conserve energy by redirecting nutrients away from non-essential functions such as hair growth.

Why Does Anorexia Cause Hair Loss?

Healthy hair growth requires adequate protein, iron, zinc, essential fatty acids, and B vitamins. During starvation or severe restriction, the body prioritizes vital organs like the heart and brain.

As a result, many hair follicles prematurely enter the resting phase of the growth cycle. This leads to a form of diffuse shedding known as telogen effluvium. Hormonal changes, including reduced estrogen levels, further weaken follicles and slow regrowth.

Common Signs Of Hair Loss Caused By Anorexia

Hair loss related to anorexia typically affects the entire scalp rather than forming patches. Common signs include:

Noticeable thinning across the scalp
Excessive shedding during washing or brushing
Dry, brittle, and fragile hair texture
Slower hair growth and increased breakage

Some individuals may also develop lanugo, a fine body hair that appears as the body attempts to retain heat during extreme weight loss.

How To Treat Hair Loss Caused By Anorexia

Nutritional Rehabilitation

Restoring adequate nutrition is the most important step. A structured plan developed with an eating disorder specialist or dietitian should focus on sufficient calories, protein, iron, zinc, omega-3 fatty acids, and B-complex vitamins.

Hair regrowth cannot occur until the body feels safe and nutritionally stable.

Psychological And Stress Support

Chronic stress and anxiety disrupt hormonal balance and prolong shedding. Therapy approaches such as CBT or DBT play a central role in recovery and indirectly support hair regrowth.

Mental health stabilization is as important as physical nourishment.

Gentle Hair Care Practices

Hair weakened by malnutrition is more prone to breakage. Heat styling, tight hairstyles, and harsh products should be avoided.

Using mild shampoos, minimizing mechanical stress, and allowing hair to air-dry can reduce further damage during recovery.

Medical And Dermatological Support

In some cases, dermatologists may recommend topical treatments to support regrowth once nutrition is restored. These options should only be considered as supportive measures, not primary solutions.

Medical supervision is essential, especially when hair loss persists after weight stabilization.

Is Hair Loss From Anorexia Reversible?

Yes, in most cases anorexia-related hair loss is reversible. Once consistent nutrition is restored and hormonal balance improves, hair follicles gradually return to their normal growth cycle.

Regrowth usually begins several months into recovery. Full density may take longer, and patience is required. Ongoing restriction or relapse can delay or reverse progress.

When To Seek Professional Help

Hair loss associated with anorexia signals a serious level of physical stress. Anyone experiencing ongoing shedding alongside disordered eating should seek medical and psychological support promptly.

Early intervention improves both overall recovery outcomes and the likelihood of full hair regrowth.
