Hi girls, I’m Efi! Every year, as the weather starts to warm up in Corfu, the same scene begins at our salon: clients who have just gotten a gorgeous balayage ask us “how can I keep it shiny all summer long?”
We completely understand the anxiety. You’ve invested time and money in your color, you left our team chair at our salon in Alepou with a smile, and now you’ve planned dives in Paleokastritsa, Glyfada or Agios Gordios. But the joy of the sea hides an invisible enemy: the combination of UV radiation, salinity and chlorine.
Hair sunscreen is literally your number one ally in this battle. After years in the hairdressing profession along with the rest of the team at Scissors by Effi, I guarantee you that no client has ever regretted adding it to their routine.
In this guide, we will explain in detail why the sun literally “eats” your balayage, how to choose the right hair sunscreen for dyed hair, and we will reveal 7 practical secrets for proper hair care in the summer that we apply daily at our hair salon in Corfu.
So let’s get you properly prepared before you go to the beach!

Why the Sun Is the No. 1 “Enemy” of Your Balayage
How UV radiation affects dyed wool
When UV radiation hits your hair, it does not one but two bad jobs. On the one hand, UV-A breaks down melanin and the artificial pigments in hair dye, the very ingredients you pay for at the salon. On the other hand, UV-B destroys keratin, the protein that keeps hair strong and elastic.
According to findings from the American Academy of Dermatology, prolonged exposure to the sun can cause hair to weaken, split ends, and gradually lose shine. In balayage in particular, which has undergone a decapitation process, the effects are multiplied because the hair is already more porous and vulnerable.
Seawater, chlorine and wind — the sun’s invisible allies
But the sun doesn’t work alone. It has three powerful allies working alongside it:
- Seawater: Salt acts as a dehydrating agent, sucking water from the hair and leaving it dry and damaged.
- Pool chlorine: You can’t imagine how many clients come to our salon with blonde balayage that has turned green! Chlorine oxidizes with the minerals in the water and creates these unpleasant greenish hues.
- Wind: In Corfu we are well aware of the wind that dries hair quickly and makes it prone to breakage.
Why balayage hair is more at risk
The balayage technique involves opening the cuticle through decapitation. This means that dyed hair is naturally more porous than virgin hair. The more porous the hair is, the faster it absorbs seawater, chlorine, and any “hostile” elements. This is why the right hair sunscreen for dyed hair is not a luxury but a necessity.
Signs that your Balayage is Sun Damaged
How do you know if the sun has done its damage? Here are the 5 most common signs that our team sees every day at the salon:
- Orange or yellow undertone: Your cool blonde balayage has become “warmer” — more yellow or even orange. In hairdressing, we call it the “brassy effect.”
- Dry, “straw-like” ends: The ends lack elasticity and break easily when combing.
- Loss of shine: The shine you had when you left our chair has completely disappeared.
- Difficulty detangling: Hair tangles easily, especially after being in the sea.
- Non-functional products: The products you used to use don’t seem to be doing their job like they used to.
If you recognize 2 or more of these signs, we recommend that you book an online appointment at Scissors by Effi for a reassessment. Our team will review the situation and recommend a personalized treatment.
What Exactly Is Hair Sunscreen?
Here’s the good news: hair sunscreen works on the same philosophy as facial sunscreen, but with a completely different formula. It contains UV filters that form a protective film around each hair. This invisible film:
- Reflects part of the UV radiation before it reaches the melanin
- Seals the cuticle, i.e. the outer layer of the hair
- Prevents excessive absorption of seawater and chlorine
The 3 basic types of sunscreen hair
Spray: It is the easiest to use, suitable for every type of hair. Spray from a distance of 15-20 centimeters on the lengths and especially on the ends.
Oil: Richer in texture, ideal for thick or very dry hair. A few drops are enough, spread them with your palms and comb through.
Leave-in cream: Combines sun protection with hydration. A good choice for medium and long hair.
At our hair salon in Corfu we usually recommend a spray or oil, depending on your hair type and frequency of sun exposure. If you want a personal recommendation that suits your hair type, you can request a personalized quote and we will guide you exactly.
Hair Sunscreen for Colored Hair: What to Look for
Here’s the rub. Not every hair sunscreen is suitable for anyone with balayage, highlights, or full-on color. The right hair sunscreen for color-treated hair must contain certain ingredients:
✅ UV filters (essential, look for “UVA” and “UVB protection” on the packaging) ✅ Color-lock ingredients (keep the color locked in the hair) ✅ Sulfate-free formula (sulfates wash out the color faster) ✅ Antioxidants (vitamin E, panthenol — neutralize free radicals) ✅ Proteins or hydrolyzed keratin (repair the cuticle)
❌ Avoid: Alcohol in high percentages (dries out hair), heavy silicones (accumulate over time), aromatic substances in high concentration (may irritate).
In our salon we have selected specific professional products that meet all of the above criteria. If you would like a personal recommendation for the product that suits your hair type, you can always contact us and we will be happy to guide you.
7 Secrets to Protect Your Balayage Before the Beach
Here is the gist of the guide. The 7 practical secrets that our team applies and recommends daily to those who come to our hair salon in Alepou:
1. Pre-shampoo Treatment on the Eve of the Beach
The day before you go to the beach, apply an intensive keratin or protein hair mask. Leave it on for 20-30 minutes. The goal is to “fill” the porosity of your hair so that when it’s exposed to the sea the next day, it absorbs as little salt as possible. It’s like watering a plant before putting it out in the sun. This step alone makes a huge difference in how much the color fades.
2. Wet Your Hair with Fresh Water Before Diving
Top secret from our team: before you get in the sea or pool, wet your hair thoroughly with fresh water from the shower or a bottle. A hair saturated in fresh water absorbs much less salt or chlorinated water. Think of it like a sponge: if it’s already full, it can’t hold any more. It’s a secret that professional swimmers have been using for decades.
3. Apply Hair Sunscreen in the Right Spots
After wetting your hair with fresh water, apply your hair sunscreen. Spray or spread it on the lengths and especially on the ends. NOT on the roots — it will weigh it down and make the hair look greasy. Repeat every 2 hours and definitely after each swim. It’s just like facial sunscreen: one application is not enough for the whole day.
4. Choose a Hairstyle That Limits Exposure
Braids, high buns, headbands, or scarves — all drastically reduce the amount of hair exposed to radiation. Plus, a wide-brimmed hat not only protects you but also makes you instantly glamorous in your summer beach photos. On our team’s Instagram, you’ll see dozens of hairstyle ideas from our clients.
5. Repeat the Application Systematically
As we said above, hair sunscreen loses its effectiveness over time, especially after contact with water. Keep the bottle in your beach bag and reapply every 2 hours or so. If you’re one of those people who goes for ten dips an hour, reapply sunscreen after every two. It’s better to spend a little more on product than to have to do balayage again in September.
6. Recovery Routine When You Return from the Beach
The battle doesn’t end when you leave the beach. When you return home:
- Rinse immediately with lukewarm fresh water (before the salt dries on the hair).
- Use a sulfate-free shampoo that is specifically designed for color-treated hair.
- 1-2 times a week, do a deep conditioning mask for 15-20 minutes.
- Before drying, spray leave-in conditioner for extra protection and detangling.
This four-step routine is the foundation of proper summer hair care and can literally double the lifespan of your balayage.
7. Book an Appointment for a Professional Gloss Treatment
Every 6-8 weeks, especially during the summer months, we welcome you to our salon for a gloss treatment. It’s a quick professional service (usually completed in 45-60 minutes) that revitalizes the color, seals the cuticle, and restores that shiny texture you had when you first got your balayage. It’s literally the most affordable way to keep your color in tip-top shape.
Summer Hair Care: Beyond the Products
Proper summer hair care isn’t just about products. It’s also about how you live your life in general. Here are some practices that our team constantly emphasizes to our clients:
Water, water, and more water: The more water you drink, the better you hydrate your hair from the inside out. Aim for at least 2 liters a day during the warmer months.
Diet rich in omega-3 and biotin: Fatty fish (salmon, sardines), eggs, almonds, walnuts, avocados, and chia seeds — all nourish hair from the root.
Fewer heat tools: Give your blow dryer and straightener a break. When possible, let your hair dry naturally. The combination of sun and heat from appliances multiplies the damage.
Silk pillowcase: It may sound trivial, but it reduces friction while you sleep and keeps the cuticle closed.
Fewer washes: In the summer, hair dries out more easily. 2-3 washes a week are usually enough. On the days in between, use dry shampoo if necessary.
Why Proper Protection Is Particularly Critical in Corfu
Anyone who lives in Corfu knows how intense our sun is from May to early October. Whether you prefer to take a dip in Kanoni near the city center, or travel further north to Sidari or Paleokastritsa — your hair is exposed to hours of increased UV radiation, often over 8 hours a day.
This means that a comprehensive protection routine is not a “nice-to-have”, it is a necessity. Our team at the salon sees the difference every day between clients who follow the right routine and those who don’t. The difference is like night and day — and this is especially noticeable in September.
If you happen to live in the wider Corfu area — city center, Alepou, Triklino, Solari or surrounding villages — you can easily visit us for a consultation or a quick color refresh service. We are here to help you all year round.

FAQs
How often should I apply hair sunscreen at the beach?
Every 2 hours or so, and definitely after any swimming or heavy sweating. If you stay mostly in the shade under an umbrella, a well-applied dose in the morning can last for 3-4 hours.
Is it safe to swim with balayage?
Of course it is! Just follow a proper protection routine. Wet with fresh water before diving, apply hair sunscreen, and wash your hair thoroughly when you return. Most importantly, don’t let salt or chlorine dry on your hair for hours.
When should I refresh my balayage in the summer?
During the summer months, due to intense radiation and contact with sea-chlorine, our team recommends balayage refresh every 8-10 weeks, instead of the 12-14 weeks that is the usual interval during the rest of the year.
Can I make hair sunscreen at home with natural ingredients?
No, and we really wouldn’t recommend it. Professional UV filters are lab-tested and certified. Homemade “solutions” (like pure coconut oil or olive oil) don’t offer the same protection and in some cases may even amplify the damage by acting like a lens that draws in the sun.
What do I do if my blonde hair turned green from the pool?
What do I do if my blonde hair turned green from the pool? First of all, calm down — it’s reversible! Come to our hair salon in Corfu for a clarifying treatment followed by toning. In just one visit, the greenness is gone. From there, wet your hair with fresh water before getting in the pool and always apply hair sunscreen for colored hair.
Πόσο κοστίζει ένα gloss treatment στο Scissors by Effi;

Do you serve clients from all over Corfu?
Yes, of course! At our salon we welcome clients from Corfu Town, Alepou, Triklino, as well as the surrounding areas. You can book an appointment online with one click.
What is the difference between a hair sunscreen and a simple leave-in conditioner?
The leave-in conditioner moisturizes and protects against friction/heat, but does not contain UV filters. The hair sunscreen is specifically designed with UV filters that reflect sunlight. Ideally, you use both together for complete protection.
