If you're constantly battling frizzy hair, you're not alone. Whether your hair becomes fluffy the moment you step outside, feels dry after colouring, or never seems to stay smooth after styling, frizz is one of the most common hair concerns.
The good news? Frizz isn't your hair type. It's often a sign that your hair needs more moisture, protection, or a few simple changes to your routine.
In this guide, we'll explain what causes frizz, how to prevent it, and the best professional products to help you achieve smoother, healthier, more manageable hair every day.
What Causes Frizzy Hair?
The most common cause of frizz is dryness.
Each strand of hair is protected by a layer called the cuticle. When your hair is healthy and hydrated, the cuticle lies flat, creating smooth, shiny hair. When your hair becomes dry or damaged, the cuticle lifts, allowing moisture from the air to enter the hair shaft. This causes the hair to swell, resulting in frizz.
This is why humidity often makes frizz worse. Dry hair absorbs moisture from the air much more readily than healthy, hydrated hair.
The key to reducing frizz is simple: keep your hair moisturised, minimise damage, and protect it from heat and environmental stress.

10 Common Causes of Frizzy Hair (And How to Fix Them)
1. Washing Your Hair with Water That's Too Hot
A long, hot shower might feel relaxing, but it can strip away your hair's natural oils. These oils help lock in moisture and keep your hair smooth.
Instead, wash your hair with lukewarm water and finish with a cool rinse if you can. This helps smooth the cuticle and retain moisture.
2. Drying Your Hair Too Roughly
Rubbing your hair vigorously with a towel creates friction, which roughens the cuticle and increases frizz.
Instead, gently squeeze excess water from your hair using a microfibre towel or a soft cotton T shirt. This helps reduce breakage and leaves the cuticle smoother.
3. Skipping Heat Protection
Using a hair dryer, straightener, or curling iron without heat protection can quickly dry out your hair and lead to damage.
Always apply a heat protectant before styling, even if you're only blow drying.
We recommend: Redken Extreme Play Safe Treatment 200ml
Redken Extreme Play Safe is a multi benefit leave in treatment that helps protect hair from heat styling while strengthening and repairing damaged hair. Infused with plant proteins and tourmaline, it helps reduce the appearance of split ends by 70%, fortifies hair fibres for 28% less breakage, and provides heat protection up to 232°C. It's an excellent choice for anyone who regularly uses blow dryers, straighteners, or curling irons and wants smoother, healthier looking hair.
4. Using the Wrong Hair Brush
Not all brushes are created equal. Poor quality brushes can pull on the hair, create static, and cause unnecessary damage.
Choosing a high quality brush helps detangle more gently while reducing breakage and frizz.
We recommend: ghd The All Rounder Paddle Brush
The ghd Paddle Brush is perfect for detangling longer hair, smoothing during blow drying, and creating sleek everyday styles with less static and fewer flyaways.
5. Washing Your Hair Too Often
Shampooing every day can remove the natural oils your hair needs to stay hydrated.
For most hair types, washing two or three times a week is enough. On the days in between, your scalp's natural oils help nourish and protect your hair.
6. Using Heat Styling Every Day
Regular use of hot tools can gradually weaken the hair, making it more prone to dryness and frizz.
If possible, give your hair regular breaks from heat styling. When you do use heat, always apply a heat protectant first.
We recommend: Pureology Colour Fanatic Spray 200ml
This lightweight multi tasking leave in spray detangles, protects against heat, adds shine, and helps keep colour treated hair healthy and manageable. It's an excellent daily companion for anyone who regularly styles their hair.
7. Waiting Too Long Between Haircuts
Split ends don't repair themselves. Over time, they travel further up the hair shaft, making hair appear rough, dry, and frizzy.
Regular trims every six to eight weeks help maintain healthier ends and prevent further damage.
8. Using Harsh Shampoos
Some shampoos contain ingredients that can strip away moisture, leaving hair dry and difficult to manage.
Choosing a professional sulphate free shampoo designed for smoothing or hydration can make a noticeable difference.
We recommend: Pureology Smooth Perfection Shampoo 266ml
Pureology Smooth Perfection Shampoo gently cleanses while helping to reduce frizz and improve manageability. Formulated for colour treated hair, it provides long lasting smoothness while leaving hair soft and shiny.
9. Chemical Services
Lightening, colouring, perming, and other chemical services can weaken the hair if it's not properly cared for.
That doesn't mean you need to avoid these services. It simply means your home care routine becomes even more important.
Adding a weekly strengthening treatment helps maintain healthy hair between salon visits.
We recommend: K18 Leave-In Molecular Repair Hair Mask 50ml
K18 Molecular Repair Hair Mask is a leave in treatment that works to repair damage caused by colouring, bleaching, chemical services, and heat styling. In just four minutes, it helps restore strength, softness, and smoothness, leaving hair healthier, more resilient, and easier to manage. By improving the overall condition of the hair, K18 helps reduce the dryness and damage that often lead to frizz.
10. Humidity
Humidity doesn't actually cause frizz. Instead, it exposes hair that's already dry or damaged.
Healthy, hydrated hair is much less likely to react to moisture in the air.
If you're travelling to a humid climate or simply dealing with muggy weather, using products specifically designed to fight humidity can help keep your style under control.
We recommend: Redken Frizz Dismiss Shampoo 300ml
This gentle sulphate free shampoo cleanses while helping to smooth frizzy hair and improve shine. Formulated with Redken's Smoothing Complex and Babassu Oil, it's ideal for managing unruly hair.

This leave in smoothing cream hydrates, detangles, protects against heat up to 230°C, and helps defend hair against humidity while keeping it soft and manageable.
A Simple Anti Frizz Hair Routine
Building a consistent routine is one of the easiest ways to reduce frizz over time.
Step 1: Wash with a hydrating or smoothing shampoo.
Step 2: Follow with a nourishing conditioner every wash.
Step 3: Apply a leave in treatment or heat protectant before styling.
Step 4: Use quality styling tools and avoid unnecessary heat where possible.
Step 5: Incorporate a repairing treatment into your routine once a week.
Step 6: Book regular trims to keep split ends under control.
Small changes like these can make a significant difference to the health and appearance of your hair.
Frequently Asked Questions
Why is my hair always frizzy?
Frizz usually occurs when the hair is dry or damaged. Raised cuticles absorb moisture from the air, causing the hair to swell and become difficult to manage.
Does humidity cause frizz?
Humidity doesn't create frizz on healthy hair. It simply makes existing dryness and damage more noticeable by allowing moisture to enter the hair shaft.
Can damaged hair become smooth again?
While split ends need to be trimmed, damaged hair can become healthier with regular hydration, strengthening treatments, heat protection, and professional haircare.
What products are best for frizzy hair?
Look for products that provide hydration, smoothing benefits, heat protection, and humidity resistance. A combination of a professional shampoo, leave in treatment, and weekly repair treatment will usually deliver the best results.
