Monsoon hair fall is real and the culprit might be your scalp
First come the clouds, then comes the hair fall. You find it on your pillow, in your brush or coiled around your bathroom drain. Monsoon hair fall isn’t just seasonal drama: it’s biology, scalp science and sometimes, neglect. Rainwater dries on your roots, sebum gets trapped under sweat and your scalp turns into a damp buffet for fungal growth.
The good news is that it’s rarely permanent. The better news is that it doesn’t require a 12-step routine but a shift in how you care for your scalp when there's high humidity.
Why monsoon hair fall happens in the first place
Monsoon hair fall can be a byproduct of humidity, inflammation and a disrupted scalp microbiome. “High humidity traps sweat and sebum, disrupting the scalp’s microbiome and encouraging overgrowth of Malassezia fungi and certain bacteria,” a dermatologist tells Vogue India. “This leads to itching, inflammation and flaking. Think of your scalp in the monsoon as a tropical greenhouse—warm, damp and perfect for fungal overgrowth.”
And it’s not just seasonal chaos. A celebrity skin expert explains, your scalp is “a mini-ecosystem”—home to nearly 1,00,000 follicles and vulnerable to build-up from natural oils, sweat and product residue. “It’s important to treat the scalp like you’d treat your face.” Skipping too many wash days or letting rainwater dry on your scalp only worsens this imbalance.
How to reduce hair fall during the monsoon season
Clarify, don’t strip
Use a gentle exfoliating or clarifying shampoo once a week to dislodge build-up. Avoid harsh surfactants, but look for scalp-focused ingredients like salicylic acid, piroctone olamine or tea tree oil to counter fungal overgrowth.
Don’t let rainwater sit
Rainwater is often acidic and full of pollutants. Letting it dry on the scalp without rinsing can worsen flaking, itching and breakage. “Careful drying after every wash and avoiding rainwater on the scalp” are key steps, says a Dr.
Keep conditioners off your roots
This should be the rule, regardless of the season. Apply conditioner only to mid-lengths and ends, and rinse thoroughly. If you have finer hair, a lightweight conditioner is enough. Skip leave-ins and heavy oils that weigh the scalp down or clog follicles.
Avoid wet-hair brushing (unless necessary)
Hair absorbs moisture, which causes it to swell and more prone to breakage. Avoid brushing your hair when it's wet. For people with curly hair, a wet-brushing is often a part of their CGM routine. Be as gentle as you can.
Reframe your relationship with oiling
Dr Prachi Bodkhe, dermatologist at Envi Aesthetics, says, “Heavy, sticky oils like castor oil, mineral oil or thick unprocessed coconut oil should be avoided, as they can trap sweat and dirt, making the scalp a breeding ground for yeasts, other fungal flare-ups and hair follicle infections. Avoid overly fragranced oils as they may irritate an already sensitive scalp.”
If you’re prone to dandruff or seborrheic dermatitis, skip oiling altogether.
You may think that you're shedding like a German Shepherd, but stress will make the situation worse. Focus on scalp-first care, and if you're losing an immense amount of hair for a long period of time, a trip to the doctor is worth it.
