How Stress and Poor Nutrition Are Making You Lose Your Hair — And What to Do About It

How Stress and Poor Nutrition Are Making You Lose Your Hair — And What to Do About It - Tasic Pure Oils

Introduction: The Hair-Body Connection

Your hair is a mirror of your internal health. It is one of the first body systems to reflect the state of your nutrition, your hormone levels, and your stress load — and one of the last to receive nutrients when your body is under duress. If you've been experiencing increased shedding, thinning, or a lack of growth and you've ruled out external causes, it may be time to look inward.

The connection between stress, nutrition, and hair loss is not a wellness myth. It is a well-documented, extensively researched biological reality — and understanding it is the first step to doing something about it.

The Problem: Shedding That Seems to Come From Nowhere

Telogen effluvium (TE) is the medical term for diffuse hair shedding triggered by a physiological or psychological stressor. It is characterised by a sudden, significant increase in the number of hairs entering the telogen (resting/shedding) phase, resulting in noticeable shedding across the entire scalp — typically 2–3 months after the triggering event.

According to a review published in the Journal of Clinical and Aesthetic Dermatology, telogen effluvium is one of the most common forms of hair loss seen in clinical settings, affecting women disproportionately. Triggers include major illness, surgery, childbirth, crash dieting, significant emotional stress, and nutritional deficiencies.

The Emotional Weight of Hair Loss from Stress

There is a cruel irony in stress-related hair loss: the hair loss itself becomes a source of stress, which can perpetuate further shedding in a devastating feedback loop. Research published in the British Journal of Dermatology documented that hair loss — regardless of cause — is associated with significant psychological distress, including depression, anxiety, and reduced social functioning.

For many people, noticing their hair thinning in the months following a stressful event is confusing and frightening. They don't connect the hair loss to its root cause, and they don't know what to do about it. This post is here to change that.

How Stress Affects the Hair Growth Cycle

The Biology of Stress-Induced Hair Loss

When the body experiences significant psychological or physical stress, it activates the hypothalamic-pituitary-adrenal (HPA) axis, releasing cortisol and other stress hormones. Research published in Nature (Kim et al., 2021) demonstrated that elevated cortisol levels directly inhibit the activation of hair follicle stem cells — the cells responsible for initiating each new anagen (growth) phase.

In practical terms: chronic stress keeps your follicles stuck in the resting phase, preventing them from transitioning into active growth. The result is diffuse thinning, increased shedding, and the heartbreaking experience of watching your hair seemingly disappear without explanation.

The Role of Nutrition in Hair Loss

Hair follicles are among the most nutritionally demanding structures in the body. They require a continuous, optimal supply of specific micronutrients to function properly. When nutritional intake is inadequate — through poor diet, restrictive eating, malabsorption, or increased metabolic demand — the body prioritises essential organs, and the hair follicle is among the first to be deprived.

Key nutrients whose deficiency is linked to hair loss:

  • Iron: Iron deficiency (even without anaemia) is the most common nutritional deficiency associated with hair loss in premenopausal women. A study in the Journal of the American Academy of Dermatology found that serum ferritin levels below 30 ng/mL were significantly correlated with increased shedding.

  • Biotin (Vitamin B7): Biotin deficiency is associated with brittle hair and diffuse alopecia. While true deficiency is rare in developed countries, subclinical deficiency is more common than recognised.

  • Zinc: Zinc plays a critical role in DNA synthesis and protein production within the hair follicle. Zinc deficiency has been found in multiple studies to correlate with alopecia, particularly in telogen effluvium cases.

  • Vitamin D: Receptors for vitamin D are found in hair follicle cells. Research published in Skin Pharmacology and Physiology found that vitamin D deficiency was significantly more prevalent in women with female pattern hair loss and telogen effluvium compared to controls.

  • Omega-3 Fatty Acids: These essential fats support scalp health, reduce inflammation, and have been shown in a 2015 study in the Journal of Cosmetic Dermatology to reduce hair loss and improve hair density when supplemented over 6 months.

A Two-Front Approach

Internal: Nutrition and Stress Management

Address nutritional deficiencies through a diet rich in iron (lean meats, legumes, dark leafy greens), zinc (seeds, nuts, shellfish), biotin (eggs, sweet potatoes), vitamin D (fatty fish, fortified foods, sunlight), and omega-3s (salmon, walnuts, flaxseed). Consider a comprehensive blood panel to identify specific deficiencies. Manage stress through regular exercise, mindfulness practice, adequate sleep, and professional support where needed.

External: Long And Strong Hair Care System by Tasic Pure Oils

While addressing internal contributors is essential, external support is equally important — particularly in the recovery phase, when the hair needs maximum nourishment as new growth emerges. Long And Strong supports your external hair health by:

  • Nourishing the scalp to create an optimal environment for new follicle activation
  • Strengthening existing strands to minimise breakage during the vulnerable regrowth period
  • Delivering anti-inflammatory botanical ingredients that calm a stress-reactive scalp
  • Providing essential fatty acids topically to support scalp barrier function


Used consistently during recovery from stress-related hair loss, Long And Strong helps ensure that every hair your follicles produce is as strong, nourished, and resilient as possible.

Final Thoughts

If your hair is falling out, your body is telling you something important. Listen to it. Address the internal causes through nutrition and stress management — and support your hair externally with the targeted nourishment of Long And Strong. Recovery is possible, and it starts with understanding.
