In this detailed blog post, we will uncover: Major causes of hair fall

• Vitamin and nutrient deficiencies responsible for weak hair

• Common lifestyle and grooming mistakes

• Scientifically backed ways to fix hair loss naturally

Let’s dive deep into everything you need to know to stop hair fall and restore healthy hair growth.

Let’s start by identifying the main triggers of hair fall, which often work together and not in isolation

🔸 Vitamin D Deficiency

Low Vitamin D levels shrink hair follicles and disrupt hair growth cycles.

Fix:

Get 15–20 minutes of sunlight daily

include eggs, mushrooms, and fortified dairy in your diet

🔸 Biotin (Vitamin B7) Deficiency

Biotin helps in keratin production — the protein that forms hair. Deficiency leads to hair thinning.

Fix:

Eat almonds, walnuts, sweet potatoes, and bananas

🔸 Vitamin B12 Deficiency

Low B12 levels affect oxygen supply to hair follicles, slowing growth.

Fix:

Consume dairy, fish, and B12 supplements (especially for vegetarians)

🔸 Iron Deficiency (Anemia)

Iron helps red blood cells carry oxygen to hair roots. Low levels weaken follicles.

Fix:

Add spinach, lentils, pumpkin seeds, and red meat to your diet

🔸 Zinc Deficiency

Zinc helps tissue growth and repair. Lack of it can lead to hair loss and scalp issues.

Fix:

Eat pumpkin seeds, chickpeas, and shellfish

Hair is made of keratin, a type of protein. Inadequate protein leads to weaker hair strands, breakage, and shedding.                                                      fix:                                                                             :          Add protein-rich foods: eggs, dairy, tofu, paneer, lentils, chicken                                                                    Eat a balanced diet including healthy fats and omega-3s                                                                     

🔸Emotional Stress (Telogen Effluvium)

After emotional trauma or chronic stress, hair enters the resting phase, leading to sudden shedding.    

Fix:

Practice meditation, yoga, or breathing exercises daily

Get 7–8 hours of sleep

🔸 Hormonal Changes

PCOS, thyroid issues, menopause, or post-pregnancy hormonal shifts can disrupt hair growth.

Fix:

Consult a doctor for proper diagnosis and hormone testing

Focus on whole foods, regular exercise, and stress reduction

Many people unknowingly damage their hair through common grooming mistakes.

❌ Over-Washing or Under-Washing

Washing too often strips natural oils; not washing enough leads to scalp buildup.

Fix:

Wash hair 2–3 times a week depending on scalp type

❌ Using Hot Water

Hot water dries out the scalp and causes breakage.

Fix:

Use lukewarm or cold water for rinsing

❌ Tight Hairstyles

Constant ponytails or buns stress hair follicles and cause traction alopecia.

Fix:

Keep hair loose or in soft hairstyles

🛢 5. Wrong Hair Oils & Products

Some oils and styling products can clog pores or irritate the scalp, worsening hair fall.

🚫 Mineral Oil or Petroleum-Based Oils

These block scalp pores and do not nourish hair.

Fix:

Use cold-pressed, natural oils like coconut oil, castor oil, argan oil

🚫 Sulfate or Paraben Shampoos

These strip moisture and irritate the scalp.

🔸 1. Telogen Effluvium

Triggered by:

Surgery

Childbirth

Fever (post-COVID)

Stress

Sudden diet changes

Hair enters the resting phase abruptly and falls in clumps.

🔸 2. Alopecia Areata (Autoimmune Hair Loss)

Your immune system attacks hair follicles.

Shows up as patchy bald spots.

🔸 3. PCOS (Polycystic Ovary Syndrome)

Hormonal imbalance increases androgens → hair thinning on the scalp, growth on the face.

🔸 4. Thyroid Disorders

Both hypothyroidism and hyperthyroidism can thin out hair.

🔸 5. Fungal Infections

Dandruff, psoriasis, or ringworm can block follicles and affect growth.

Cortisol, the stress hormone, shrinks follicles and shortens the anagen (growth) phase.

Poor sleep disrupts melatonin, which regulates hair growth.

Fix:

7–8 hours of quality sleep

Deep breathing, mindfulness, or yoga

Reduce screen time before bed
