Sudden increases in hair shedding are most often caused by telogen effluvium, a temporary shift in the hair growth cycle triggered by stress, illness or fever, surgery, childbirth, rapid weight loss, or a new medication, usually showing up two to three months after the trigger. Other frequent causes include iron, vitamin D, or protein deficiency, thyroid disease, hormonal changes such as PCOS or menopause, genetic pattern hair loss, autoimmune alopecia areata, scalp conditions like seborrheic dermatitis or fungal infection, and tight hairstyles that pull at the roots. Patchy bald spots, scalp pain or scarring, or shedding paired with fatigue, weight changes, or irregular periods point to causes that need medical evaluation rather than watchful waiting. How long the shedding has lasted, whether it is diffuse or localized, and which other symptoms accompany it all change what is likely going on and what treatments help, so see below for the important details before assuming it will resolve on its own. Because the same amount of hair loss can mean anything from a passing stressor to an untreated thyroid or nutritional problem, a free, instant, online symptom check can help you sort through your specific pattern and symptoms and understand which next step, and which type of clinician, makes sense for you.

Why Is My Hair Falling Out More Than Usual?
Hair naturally goes through growth, rest and shedding phases. It’s normal to lose 50–100 hairs a day. But if you suddenly notice more strands on your brush, pillow or in the shower drain, it’s natural to wonder “why is my hair falling out more than usual?” Below, we look at common causes, when to worry and practical steps you can take.
Understanding Normal Hair Shedding
Hair grows in cycles:
At the end of telogen, old hairs fall out to make room for new growth. If more hairs enter telogen at once, you’ll notice shedding beyond the usual 50–100 strands a day.
Common Causes of Increased Hair Fall
Physical or Emotional Stress
• Major surgery, serious illness or high fever
• Emotional upheaval (bereavement, job loss, relationship stress)
• Childbirth (often 2–4 months after delivery)
– This is called telogen effluvium. Hair usually regrows in 6–9 months once stress eases.
Nutritional Deficiencies
• Iron deficiency (one of the most common causes)
• Low protein intake
• Inadequate zinc, biotin or other B-vitamins
– A balanced diet with lean protein, leafy greens, whole grains and nuts supports healthy hair growth.
Hormonal Changes
• Thyroid disorders (over- or under-active thyroid)
• Polycystic ovary syndrome (PCOS) in women
• Menopause (estrogen and progesterone levels drop)
– Hormone imbalances can shift hair into the shedding phase.
Medications and Treatments
• Chemotherapy or radiation
• Blood thinners, antidepressants, beta-blockers
• High-dose vitamin A or retinoids
– Check with your doctor or pharmacist about side effects.
Genetic Factors
• Androgenetic alopecia (male- or female-pattern baldness)
– Often begins gradually with thinning at the temples or crown in men, widening part in women.
Autoimmune Conditions
• Alopecia areata causes patchy hair loss when the immune system attacks follicles
• Lupus can lead to diffuse thinning or scarring alopecia
– A dermatologist can diagnose and treat these conditions.
Scalp Health and Hair Care
• Over-styling (tight ponytails, braids or buns) causes traction alopecia
• Harsh chemicals (bleaching, perms, frequent coloring)
• Infrequent washing leading to buildup of oil or dandruff
– Use gentle shampoos, avoid tight hairstyles and limit chemical treatments.
Environmental Factors
• Changes in season (more fall-phase hairs in summer)
• Sun exposure, swimming in chlorinated water
– Wear a hat, rinse hair after swimming and use UV-protective sprays.
When to Seek Medical Advice
Most causes of increased shedding are temporary and resolve in months. But speak to a doctor if you notice:
You can try a free, online symptom check, using the doctor approved Ubie Symptom Checker if you’re unsure whether your symptoms warrant a visit to the clinic.
Practical Steps to Manage and Reduce Hair Loss
Track Your Shedding
• Keep a hair‐fall diary: note how many hairs you lose daily, any new symptoms or changes in health
• Take photos of thinning areas to monitor progress
Improve Your Diet
• Aim for 1.0–1.5 g protein per kg body weight (eggs, fish, poultry, legumes)
• Eat iron-rich foods (spinach, lentils, lean red meat) and vitamin C to boost absorption
• Include sources of zinc (nuts, seeds), biotin (eggs, almonds) and omega-3 fatty acids (salmon, flax)
Adopt Gentle Hair Care
• Use a wide-tooth comb on wet hair
• Limit heat styling; air-dry when possible
• Choose sulfate-free, pH-balanced shampoos and conditioners
• Avoid tight hairstyles and give your hair regular breaks from extensions or clips
Manage Stress
• Practice relaxation techniques: deep breathing, progressive muscle relaxation or guided imagery
• Regular exercise (30 minutes most days) can lower stress hormones and boost circulation to the scalp
• Get adequate sleep (7–9 hours) to support overall health
Consider Supplements (With Caution)
• Only if testing shows a deficiency (eg, iron or vitamin D)
• Avoid high-dose supplements without medical supervision
• Talk to your healthcare provider before starting any new supplement
Professional Treatments
• Topical minoxidil (over-the-counter foam or solution) can help certain types of hair loss
• Finasteride (prescription pill) for men with androgenetic alopecia
• Platelet-rich plasma (PRP) injections or low-level laser therapy under dermatologist guidance
– Always discuss risks, benefits and realistic expectations with your doctor.
When to Be Concerned
If hair fall is accompanied by:
…see a healthcare provider promptly. Some serious conditions—like thyroid disease, autoimmune disorders or infections—require early diagnosis and treatment.
Key Takeaways
If you’re worried about your hair loss or notice any alarming symptoms, speak to a healthcare professional for personalized advice.
