The monsoon season in Mumbai brings welcome relief from the scorching heat, but it also brings a surge of monsoon hair fall that catches most people off guard. If you have been noticing more hair on your pillow, in your shower drain, or on your brush during the rainy months, you are not alone. Increased hair shedding during the rainy season is one of the most common concerns we see at Adore Skin Clinic, and the good news is that it is largely preventable and treatable with the right care.
In this guide, our dermatology experts break down exactly why hair fall during the rainy season spikes and the science-backed tips you need to protect your hair health through every monsoon.
Why Does Monsoon Cause Hair Fall?
Before you can tackle seasonal hair fall, it helps to understand what is actually happening beneath the surface. Here are the main culprits:
- High humidity and scalp infections: Monsoon air is damp and warm, the perfect breeding ground for fungal and bacterial growth on the scalp. Dandruff, scalp folliculitis, and seborrhoeic dermatitis all flare up during this season, weakening hair at the root.
- Disruption of the hair growth cycle: Research shows that seasonal shifts in daylight and temperature can push a large number of hair follicles into the telogen (shedding) phase simultaneously, a phenomenon known as “telogen effluvium,” and monsoon is one of its biggest triggers.
- Hard and acidic rainwater: Rainwater often carries pollutants and has a different pH from what your scalp is used to. Direct exposure can strip natural oils, cause dryness, and lead to increased breakage and hair thinning during monsoon.
- Nutritional dips: Many people unknowingly experience drops in Vitamin D, iron, and zinc during the monsoon months (less sunlight exposure, dietary changes), all of which are directly linked to hair loss
- Stress and lifestyle changes: The monsoon disrupts routines, irregular sleep, indoor activity, and comfort eating, all of which can feed into stress-related hair shedding.
Expert Approved Tips to Control Monsoon Hair Fall
Keep Your Scalp Clean, But Not Over-Washed
A clean scalp is a healthy scalp. During monsoon, aim to wash your hair every 2–3 days with a mild, pH-balanced shampoo. Over-washing strips natural oils; under-washing allows fungal buildup. If you have an oily scalp or dandruff, opt for an anti-fungal or salicylic acid shampoo recommended by a dermatologist.
Rinse Rainwater Off Your Hair Immediately
Never let rainwater sit on your hair for long. The moment you get indoors, rinse with clean water and pat dry gently. Rainwater’s acidic pH and pollutant load can directly aggravate hair fall during the rainy season.
Dry Hair Completely Before Bed
Sleeping with damp hair is one of the worst things you can do during monsoon. It creates a warm, moist scalp environment that fungi love. Use a microfiber towel and allow your hair to air-dry fully before lying down. Avoid harsh heat styling on wet hair.
Oil Your Scalp Once a Week
A weekly scalp oil massage with coconut, argan, or castor oil improves blood circulation, nourishes hair follicles, and forms a protective barrier against humidity. Massage gently for 5–10 minutes, leave for 30–60 minutes, and wash off with a mild shampoo. This is one of the most effective hair fall remedies during monsoon.
Eat a Hair-Friendly Diet
Hair is made of protein, so load up on eggs, lentils, nuts, and fish. Pair these with foods rich in biotin (sweet potato, almonds), vitamin C (amla, citrus fruits), and iron (spinach, beans) to fight seasonal hair fall from within. If you are showing signs of nutritional deficiency, consult your dermatologist for a targeted supplement plan.
Switch to a Wide-Tooth Comb
Wet hair is at its weakest. During monsoons when hair is frequently damp, replace your regular brush with a wide-tooth comb and always detangle from the ends upward. Avoid elastic bands and tight hairstyles that pull on the scalp.
Use a Mild Conditioner, But Only on the Lengths
Conditioner adds moisture and reduces friction-related breakage, but applying it to the scalp can clog follicles. Always apply from mid-length to the tips. Look for lightweight, humidity-resistant formulas during the rainy season.
Treat Dandruff Aggressively
If dandruff is your trigger for hair loss in monsoon, treat it seriously. An over-the-counter ketoconazole or selenium sulfide shampoo used twice a week can significantly reduce flaking and scalp inflammation. If it persists beyond two weeks, visit a dermatologist in Mumbai for a prescription-strength solution.
Protect Your Hair from Humidity
Light hair serums containing silicone or argan oil can form a barrier against frizz and humidity-driven damage. Apply a pea-sized amount to damp hair before stepping out. Additionally, wearing a loose bun or a dry-fit cap on rainy days physically protects your strands from rainwater.
Do Not Ignore Excessive Hair Fall, See a Dermatologist
Losing 50–100 strands per day is considered normal. If you are losing significantly more, or noticing thinning patches, scalp tenderness, or widespread shedding, it is time to get a professional evaluation. What seems like monsoon hair fall could be an underlying condition like androgenetic alopecia, thyroid dysfunction, or iron-deficiency anemia that requires targeted hair fall treatment.
When Home Remedies Are Not Enough: Clinical Hair Fall Treatments
Sometimes, lifestyle changes alone are not sufficient, especially if monsoon hair fall has exposed an underlying hair loss condition. At Adore Skin Clinic, Dr. Madhavi Valvi offers clinically proven treatments tailored to your scalp and hair type:
- PRP Treatment for Hair Loss: Platelet-Rich Plasma therapy uses your own growth factors to stimulate dormant follicles and dramatically reduce hair shedding.

Frequently Asked Questions
Yes. A temporary increase in hair fall during the rainy season is normal due to hormonal shifts, humidity, and the natural telogen phase of the hair cycle. However, if shedding exceeds 150 strands/day or lasts beyond 2–3 months, consult a dermatologist.
Keep your scalp clean, oil regularly, eat protein-rich foods, rinse off rainwater immediately, and use a wide-tooth comb on wet hair. These basic monsoon hair fall remedies can make a significant difference within 4–6 weeks.
Rainwater itself is not the direct cause, but its acidic pH and pollutant content can irritate the scalp, strip moisture, and trigger hair thinning during monsoon. Always rinse hair with clean water after rain exposure.
A mild, sulfate-free shampoo is ideal for everyday use. If dandruff is a concern, use a medicated shampoo containing ketoconazole or zinc pyrithione 2–3 times a week. Always choose based on your scalp type, your dermatologist can guide you.
Typically, seasonal hair fall linked to monsoon lasts 6–8 weeks. Most people see a natural reduction in shedding as weather stabilises. If it continues beyond 3 months, it may indicate an underlying condition requiring treatment.
PRP (Platelet-Rich Plasma) is highly effective for hair fall triggered by follicle weakness, thinning, or androgenetic alopecia. While PRP for hair fall works best when started before or during the shedding phase, it delivers visible results over 3–6 sessions.
It is advisable to avoid chemical treatments during peak monsoon. High humidity affects colour absorption and can increase the risk of scalp irritation, which worsens hair fall during rainy season. Wait until weather stabilises, ideally in October, November.
Biotin, Vitamin D, Vitamin B12, Iron, and Zinc are the most critical nutrients for combating hair loss in monsoon. Have your levels tested before self-supplementing, as excess iron or Vitamin A can also cause shedding.
Yes, a weekly scalp oil massage improves circulation, strengthens roots, and conditions the scalp without causing buildup (as long as you wash it off properly). Stick to lightweight oils like argan or cold-pressed coconut oil to avoid heaviness in humid weather.
See a dermatologist for hair fall if you notice patchy bald spots, a rapidly receding hairline, visible scalp through thinning hair, scalp pain or itching, or shedding that has lasted more than 2–3 months despite home care. Early intervention leads to far better outcomes.
