Europe has been experiencing increasingly intense heatwaves in recent summers, with temperatures rising well above seasonal averages across many countries. While most people focus on protecting their skin, curly, coily and textured hair also needs extra attention during periods of extreme heat.
Unlike straight hair, curls naturally lose moisture more quickly. Add UV rays, humidity, chlorine and salt water into the mix, and it’s easy to see why so many customers struggle with dry, frizzy and undefined curls during summer. That is why curly hair in summer requires extra care.
For hair salons, beauty supply stores and retailers, this seasonal challenge also creates an opportunity. Customers are actively looking for expert advice and products that help keep their hair healthy throughout the warmer months.
Why Does Curly Hair Struggle More During Heatwaves?
Curly and coily hair naturally struggles to retain moisture because the scalp’s natural oils have a harder time travelling down the hair shaft than they do in straight hair.
High temperatures accelerate water loss, leaving strands dry, brittle and more susceptible to frizz. UV exposure, air conditioning, frequent washing, swimming pools and beach days only make matters worse, disrupting even the healthiest haircare routine.
The result?
- Frizz
- Dryness
- Split ends
- Less curl definition
- Increased breakage
Fortunately, these problems can often be prevented with the right products and routine.
The Biggest Summer Curl Problems (And How to Solve Them)
Problem #1: Frizz Takes Over
Humidity lifts the hair cuticle, allowing moisture from the air to enter the hair shaft. As the hair swells, curls become frizzy and lose their definition.
Solution:
Help customers lock moisture inside the hair instead of letting humidity take control.
Products to recommend:
- Leave-in conditioners
- Curl creams
- Lightweight hair oils
- Anti-frizz styling products
Problem #2: Dry Hair & Split Ends
Summer heat quickly depletes moisture, especially from the ends of textured hair. Without enough hydration, curls become rough, dull and more likely to break.
Solution:
Hydration should become a priority.
Recommend:
- Weekly deep conditioning treatments
- Moisturizing conditioners
- Leave-in conditioners
- Nourishing hair oils
Problem #3: Chlorine & Salt Water Damage
Swimming is great for summer, but not always for curls. Chlorine strips away natural oils, while salt water draws moisture out of the hair, making it even drier.
Solution:
Before swimming:
- Wet the hair with clean water first
- Apply a leave-in conditioner or lightweight oil
After swimming:
- Rinse immediately
- Cleanse with a gentle shampoo
- Follow with a moisturizing conditioner
Problem #4: UV Exposure
Just like skin, hair is affected by the sun. Long hours of direct sunlight can weaken the hair fibre, fade colour and reduce elasticity.
Solution:
Recommend:
- Protective hairstyles
- Hats or scarves
- Moisturizing products containing nourishing oils
- Regular deep conditioning
Problem #5: Curls Lose Their Definition
Heat, dryness and frequent manipulation often cause curls to become fluffy instead of defined.
Solution:
Instead of adding more styling products every day, refresh curls with water, a leave-in conditioner and curl cream to restore shape and bounce.
How Salons and Beauty Supply Stores Can Support Their Customers
During the summer months, customers often need extra guidance to keep their curls healthy, hydrated and defined.
Salons can use this seasonal demand to recommend hydration treatments, create personalised haircare routines and educate clients on protecting their curls during hot weather.
Beauty supply stores can also take advantage of the season by creating dedicated “Summer Curl Essentials” displays or holiday-ready bundles featuring products that work together as a complete routine.
Products formulated with moisturizing ingredients such as Shea Butter, Aloe Vera, Argan Oil, Coconut Oil, Jojoba Oil, Castor Oil, Avocado Oil and Honey are excellent recommendations for customers struggling with dryness.
Helping customers understand why each product plays a role in their routine not only improves their results but also builds trust and encourages long-term customer loyalty.
