Let's clear something up... humidity isn't your curls' enemy. Dryness is.
If you've ever left the house with beautifully defined curls only to catch your reflection later wondering where all the frizz came from, you're definitely not alone.
Summer brings sunshine, holidays, festivals and longer days outdoors. But it also brings humidity, chlorine, sea salt, UV rays and air conditioning, all of which can affect how your curls look and feel.
The good news?
Frizz isn't your hair misbehaving. It's your curls asking for moisture.
Whether you have loose curls, tight coils or 4C hair, understanding why summer frizz happens is the first step towards healthier, more hydrated hair.

In Short
Summer frizz happens because dry curly and coily hair absorbs moisture from humid air. This causes the hair cuticle to swell, making curls appear less defined and more prone to frizz. The best way to manage summer frizz isn’t to fight humidity. It’s to keep your hair consistently moisturised with a hydration-focused routine.

"Can we all agree that summer frizz has impeccable timing? Your curls behave perfectly until you've taken exactly one holiday photo."
Sound familiar?
Here's the thing...
Your routine probably isn't failing.
Your curls are simply responding to the environment around them.
Once you understand what's happening, managing summer frizz becomes much easier.
Why Does Curly Hair Get Frizzy in Summer?
Here's the tea... Humidity doesn't actually create frizz. It reveals where your hair needs moisture.
Hair is naturally hygroscopic, meaning it absorbs moisture from the air around it. Curly and coily hair has a naturally more lifted cuticle than straight hair, making it easier for moisture to move in and out of the hair shaft.
When your curls are already dry, they absorb moisture from humid air unevenly.
That's when you start noticing:
- Halo frizz
- Flyaways
- Less curl definition
- Puffiness
- Increased shrinkage
- Hair that feels dry, despite the humid weather
Healthy curls don't chase perfection. They chase moisture.
It's Not Just the Heat...
Most people blame the sunshine. But your curls are dealing with far more than that during summer.
Your hair may be exposed to:
- Humidity
- UV rays
- Chlorine
- Sea salt
- Air conditioning
- Wind
- Sweat
- More frequent washing after swimming or workouts
Each one gradually reduces moisture, making curls, coils and textured hair more vulnerable to dryness and frizz.
That's why summer haircare should always focus on hydration before styling.

Your Soft Life Summer Frizz System
Think of this as your simple summer routine not more products, just smarter haircare.
Step 1: Build Moisture at Wash Day
Healthy summer curls start in the shower.
Our Honey Love Collection is enriched with Manuka Honey and Avocado Oil to help replenish moisture from the very first step of your routine.
Choose the Moisture Rich Conditioner for your regular wash days.
If your curls feel drier than normal after swimming, travelling or spending long days in the sun, swap in the Deep Conditioning Hair Mask instead. You don't need to use both in the same wash routine the mask is your deeper conditioning treatment whenever your hair needs extra hydration.
Step 2: Give Your Curls a Drink
If there's one product we wouldn't skip during summer... It's leave-in conditioner.
Think of it as giving your curls a water bottle before they head into the heat.
Apply the Manuka Honey leave-in to soaking wet hair to help maximise moisture retention before styling.
Step 3: Lock That Moisture In
Hydration works best when it stays inside the hair.
Finish your routine with the Scalp & Hair Oil to help reduce moisture loss while leaving curls feeling soft and nourished.
Top tip: it also doubles as a nourishing pre-poo treatment before wash day.
Step 4: Style for the Forecast
Different summer days call for different styling products.
For lightweight definition and volume, our Curling Mousse helps create soft, bouncy curls.
Looking for longer-looking curls? Our Curl Elongating Gel helps define curls while helping to minimise the appearance of shrinkage.
Step 5: Refresh. Don't Restart
Not every frizzy day needs another wash day.
Sometimes your curls simply need a moisture boost.
Our Everyday Curl Refresher helps revive curls between wash days, making it perfect after a beach day, a hot commute or sleeping without your satin bonnet.

Summer Hairstyles That Help Reduce Frizz
If you're spending more time outdoors, protective and low-manipulation styles can help maintain moisture while reducing daily styling.
Summer-friendly options include:
- Wash-and-go styles
- Pineapple updos
- High puffs
- Slick backs
- Braids
- Twists
- Low buns
These styles won't stop humidity but they can help your curls stay looking fresher for longer.

Summer Frizz FAQs
Does humidity cause frizz?
Not directly. Humidity highlights dryness. When curly hair lacks moisture, it absorbs water from humid air, causing the cuticle to swell and curls to lose definition.
Why is my curly hair frizzier on holiday?
Swimming, sunshine, chlorine, sea salt, travel and air conditioning can all leave curls feeling drier than usual. Combined with humidity, this often leads to increased frizz.
Is frizz always a sign of damaged hair?
No. Some frizz is completely natural, especially during warm weather. Persistent dryness, however, may be a sign that your hair needs more moisture and conditioning.
Should I use conditioner and a hair mask together?
Usually not. Use your conditioner on regular wash days and switch to a hair mask whenever your curls feel particularly dry or need a deeper conditioning treatment.
Can I reduce frizz without washing my hair?
Yes. Refreshing curls with a lightweight curl refresher can help restore moisture and definition between wash days.
Does 4C hair get frizz in summer?
Absolutely. Like all textured hair, 4C hair can become drier during summer due to increased exposure to heat, humidity and environmental factors. A moisture-first routine can help maintain softness and definition.
