How to Fix Dry, Frizzy Hair This Summer: Causes, Solutions & Product Picks

If your hair feels dry, puffy, or impossible to manage the second summer hits, you're not alone. Heat, humidity, sun exposure, and saltwater can all strip your strands, leaving you with frizz, breakage, and that dry, crunchy texture no one asked for.

In this guide, we break down what causes frizz and dryness in summer — and the salon-quality solutions that actually work.

What Causes Frizzy, Dry Hair in Summer?

1. UV and Heat Exposure
Just like your skin, your hair can be damaged by the sun. UV rays break down the cuticle, leaving hair rough, dry, and more prone to frizz.

2. Humidity
In humid weather, moisture enters the hair shaft and causes it to swell — leading to puffiness and flyaways.

3. Saltwater and Chlorine
Both salt and chlorine dehydrate your hair and strip away natural oils, leaving it feeling brittle and coarse.

4. Overwashing or Harsh Products
Cleansing too often — especially with strong, sulphate-heavy shampoos — can strip essential moisture and damage your hair barrier.

How to Fix It: Your Summer Hair Rescue Plan

1. Switch to a Moisture-Based Shampoo and Conditioner

Look for sulphate-free formulas that gently cleanse while replenishing hydration.

Try:

• ELEVEN Smooth Me Now Anti-Frizz Shampoo & Conditioner

• Kevin Murphy HYDRATE-ME.WASH & RINSE for dry, coloured, or coarse hair

• Davroe Moisture Senses Duo for a gentle, vegan option

2. Add a Leave-In Product

Leave-ins protect your hair from heat, humidity, UV, and frizz — and they’re a must for detangling.

Try:

• NAK Hair Repl.ends Leave-In Moisturiser

• O&M Know Knott Detangler

• Juuce Smooth Enz Leave-In Moisture Treatment for smoothness and softness without the weight

3. Use a Weekly Mask or Deep Conditioner

This is your at-home treatment to help rebuild hydration and strength.

Try:

• Kevin Murphy YOUNG.AGAIN MASQUE for restoring moisture and elasticity

• Davroe MCT Moisture Conditioning Treatment

• O&M Seven Day Miracle Moisture Mask for a deep repair boost

4. Apply a Heat or UV Protectant

Whether you heat style or not, your hair needs protection from the sun.

Try:

• ELEVEN Australia Miracle Hair Treatment — UV and heat protection in one

• Kevin Murphy UN.TANGLED — detangles, strengthens, and protects from heat and environmental stress

• Pure Miracle Renew Leave-In Treatment — smoothes and shields

5. Skip the Towel Rub

Friction damages the hair cuticle and leads to more frizz. Instead, gently squeeze excess water with a microfibre towel or cotton T-shirt.

Bonus Tip: Style Smarter, Not Harder

Summer is the perfect time to embrace natural textures. Enhance waves, curls, or coils with a product designed to work with — not against — your hair type.

Try:

• Juuce Sea Air Mist for beachy, soft hold

• ELEVEN Australia Keep My Curl Defining Cream

• Kevin Murphy KILLER.WAVES for lightweight curl activation without crunch
