Why Monsoon Causes Hair Fall & How to Stop It | CAMIA Hair Care

Monsoon and Hair Fall: It's Not a Coincidence

If your hairbrush fills up faster every June, you're not imagining it. Monsoon is clinically the most common season for a spike in hair shedding, and humidity is the main culprit. What most people don't realise is that the problem doesn't start at the strand. It starts deep at the root.

Understanding the why is the first step to stopping it.

How Ambient Moisture Weakens Hair Roots

Hair is made primarily of keratin, a hygroscopic protein, meaning it absorbs moisture from the surrounding air. During monsoon, when relative humidity sits between 70–90%, your hair shaft is in a constant state of swelling and contracting as it absorbs and releases ambient moisture.

This repeated cycle does two things:

1. It disrupts the hair's pH balance.
The scalp's natural pH is mildly acidic (4.5–5.5). Prolonged exposure to rainwater,  which can be slightly acidic due to dissolved pollutants,  and high ambient humidity shifts this pH. A disrupted scalp pH weakens the hair follicle's grip on the root, loosening the anchoring of the hair shaft in the follicle. The result: strands that shed with far less mechanical force than normal.

2. It makes the hair shaft structurally brittle.
As the cuticle (the outer protective layer of each strand) repeatedly swells and contracts, it lifts and chips. This leaves the cortex,  the protein core of the strand,  exposed and vulnerable to breakage. Humid air also creates the ideal environment for fungal growth on the scalp, including Malassezia, which triggers dandruff and inflammation around hair follicles, further weakening roots.

The combination of follicle loosening + cuticle damage + scalp inflammation is what makes monsoon hair fall feel so aggressive compared to other seasons.

The CAMIA pH-Balanced Approach to Monsoon Hair Care

Addressing monsoon hair fall starts with restoring and maintaining scalp pH. CAMIA's pH Balancing Shampoo is formulated to cleanse without stripping the scalp's acid mantle,  removing excess humidity-driven sebum and fungal buildup while keeping the scalp environment stable.

Follow with the Deep Nourishment Conditioner, which works to re-seal the lifted cuticle after washing, reducing the porosity that makes monsoon-exposed hair so prone to breakage. Together, they form CAMIA's pH Balanced Hair Care Duo,  built specifically for the seasonal challenges of a tropical climate.

A note on washing frequency in monsoon:
Contrary to common belief, washing hair 3–4 times a week during monsoon is healthier than washing daily (which strips protective oils) or washing too infrequently (which allows fungal buildup). Find your scalp's rhythm and stay consistent.

Quick Guide: Low-Tension Hairstyles for Monsoon

High-tension styles,  tight ponytails, buns, braids pulled from wet hair,  apply mechanical stress directly to already-loosened follicles. During the monsoon, this is a primary trigger for traction alopecia and accelerated shedding.

Switch to these low-tension alternatives:

Golden rule: Never style hair when it's wet. Wet hair is at its weakest; the hydrogen bonds that give hair structure are broken by water. Styling, tying, or detangling wet hair in the monsoon is one of the fastest ways to accelerate shedding.

Microfiber Towel Drying: Why It Matters More in Monsoon

Standard cotton towels have a coarse, looped texture. When you rub your hair dry with one, you're creating hundreds of micro-abrasions along the raised cuticle,  especially damaging when hair is swollen with moisture and already fragile.

Microfiber towels work differently:

• Their ultra-fine fibres absorb water through capillary action rather than friction

• They dry hair 50% faster than cotton, reducing the window of vulnerability when hair is wet and weak

• They cause significantly less cuticle disruption, frizz, and breakage

How to use a microfiber towel correctly:

1. After washing, do not rub. Gently squeeze water from roots to ends.

2. Wrap hair in the microfiber towel using a "plop" method,  bend forward, lay the towel flat, lower hair onto it, and wrap loosely.

3. Leave for 10–15 minutes. The towel draws moisture out without mechanical stress.

4. Air-dry for the remainder, or use a diffuser on low heat if needed.

Frequently Asked Questions

Q: Why does hair fall increase so much during the monsoon?
A: Monsoon humidity causes the hair shaft to repeatedly swell and contract, weakening the cuticle and disrupting scalp pH. This loosens follicle grip and makes strands shed far more easily than in other seasons.

Q: Is it normal to lose more hair during the rainy season?
A: Yes,  a moderate increase in shedding during the monsoon is common and well-documented. However, if hair fall is excessive (more than 100–150 strands per day) or accompanied by scalp irritation, it's worth consulting a dermatologist.

Q: How does rainwater affect hair?
A: Rainwater in urban areas carries dissolved pollutants and can be slightly acidic. Regular exposure to rainwater disrupts the scalp's natural acid mantle (pH 4.5–5.5), weakening hair roots and increasing susceptibility to fungal infections and shedding.

Q: Should I oil my hair during the monsoon?
A: Yes,  a weekly pre-wash oil massage strengthens roots and reduces the brittleness caused by humidity-induced cuticle damage. Apply 1–2 hours before washing; avoid leaving oil on overnight during monsoon, as prolonged moisture + oil on the scalp can worsen fungal conditions.

Q: Does a microfiber towel actually reduce hair fall?
A: Yes. Microfiber towels absorb water through gentle capillary action rather than friction, dramatically reducing the cuticle damage and breakage caused by traditional cotton towel rubbing,  which is especially damaging when hair is wet and structurally at its weakest.

Q: What hairstyles should I avoid during the monsoon to prevent hair fall?
A: Avoid tight ponytails, high buns, and any style that pulls directly on the scalp,  especially on wet hair. These apply mechanical stress to already-loosened follicles and are a leading cause of traction-related hair fall during the rainy season.
