How to Protect Your Hair from Sun, Chlorine and Salt

Key points of this article:

• The sun weakens hair structure causing it to lose its natural or dyed color.
• Chlorine from pools strips natural protective oils and can give light hair a greenish tint.
• Sea salt dries out hair almost instantly, leaving it rough and brittle.
• Wetting hair with fresh water prior to swimming is the best trick so it doesn't absorb as much chlorine or salt.
• Using a hair sunscreen (like those containing Polysilicone-15) is critical to prevent hair burning.
• Salon treatments like Olaplex or capillary botox are the salvation for severely damaged manes after vacations.

Why is summer your hair's biggest enemy?

Summer on the Levantine coast is synonymous with the beach, the pool, and a dazzling sun, but for our hair, it is one of the most stressful times of the year. The intense sun of Alicante and its coasts, combined with pool chlorine and sea salt, forms a cocktail that can ruin even the best-cared mane if we do not take the necessary precautions.

Hair is made up primarily of keratin, a protein that gives it strength and elasticity. In addition, it has a natural fat layer that keeps it hydrated and shiny. When we expose ourselves unprotected to typical summer factors, we are directly attacking both its internal structure and its external protective layer.

What exactly happens to your hair at the beach or the pool?

Each of summer's "aggressors" attacks our hair in a different way:

The Sun (UV radiation)

Just as it burns our skin, the sun also "burns" hair. Ultraviolet radiation breaks down the proteins giving it strength, making hair brittle and causing the dreaded split ends. Additionally, the sun destroys pigments, explaining why hair lightens in Summer or why dyes fade so quickly.

Pool chlorine

Chlorine is a strong chemical meant to keep water clean, but runs like a harsh detergent on our hair. It sweeps away the natural oils keeping hair soft, leaving it feeling rough and difficult to comb. Furthermore, in blonde or highlighted hair, chlorine makes it easier for certain water metals (like copper) to stick to the hair, causing that unwanted greenish tint.

Sea salt

Salt acts like a sponge, absorbing moisture. When salt water dries on your hair, it draws out all the water from within, causing instant dehydration. That rough, dry texture you notice after a day at the beach is due to salt crystals stuck to the hair's surface.

Key ingredients to look for in your Summer products

To fight this continuous damage, not just any shampoo works. You need specific allies in your cosmetics:

• Hair Sunscreen Filters: Look for professional quality ingredients like Polysilicone-15. Unlike skin sunscreens which are heavy, this hair-designed filter is lightweight, leaves no greasy feel, and absorbs UVB rays perfectly.
• "Chelating" or Clarifying Shampoos: Specialized shampoos formulated to trap and remove hard water minerals and chlorine (like EDTA or Sodium Phytate). Using one weekly over Summer "resets" hair, stripping all pool residue and restoring shine.
• Oils and Botanical Extracts: Ingredients like coconut oil, argan, avocado, or shea butter are excellent at replenishing the lipid layer stolen by seawater. They penetrate deeply returning softness naturally.

Your ideal routine for hair care in summer

Maintaining healthy hair in Summer is much easier through these three key steps: before, during, and after water exposure.

1. The shower trick before swimming

This is the most important tip: never get into the pool or the sea with dry hair. Always wet your hair with fresh water at the showers before bathing. Our hair acts like a sponge; if it's already full of clean fresh water, there will be no physical space left to absorb as much salt or chlorinated water.

Along with this, always apply a good spray or cream hair sunscreen (leave-in) before leaving home, paying special attention to ends to build an extra thermal barrier.

2. Immediate washing

Don't let chlorine or salt dry under the bright beach sun. As soon as you exit the water, head to the showers and rinse hair abundantly with fresh, sweet water.

3. Intensive hydration at home

Swap out your usual shampoo for a mild and highly hydrating one, preferably organic or without harsh sulfates to prevent drying. At least once a week, take the time to apply a deep nourishing mask, allowing it to sit so hair regains all lost water.

Dry your hair gently with microfiber towels and avoid extreme heat tools (like flat irons or high power blow dryers). If usage is mandatory, always apply a thermal protector beforehand.

Protective styling: Hairstyles for the beach

A very effective, and also very trendy, way to protect your mane is to minimize the amount of hair exposed directly to the sun and wind.

Forget about wearing hair down on windy beach days, as you'll only end up with impossible knots that break when trying to comb them. Opt for popular updos like loose braids (passive beach waves), messy buns, or top knots. They shield the internal part of your mane from friction avoiding exposing its full length to UV rays.

Lean on large soft accessories like wide 90s barrettes, wide-brimmed hats, or technical caps. Hats protect your hair by limiting exposure but also shelter your scalp, averting painful burns at the part line. Additionally, switch out traditional elastic bands that break fibers for gentler options.

Is your hair already damaged? Salon rescue treatments

If you feel the damage has already been done (hair feels like "gum" when stretched, lacks shine, and split ends are uncontrollable), home masks will not be sufficient. It's time to visit your trusted hair salon in Elche for advanced rescue therapy. At Milanocenter, we evaluate your damage level and apply expert solutions:

1. Bond Multiplier Therapies (like Olaplex or K18): Revolutionary treatments operating at the hair DNA level. They don't just "makeup" the hair, they repair broken magnetic foundations and disulfide bonds from the inside after chemical or UV burns, restoring original strength—especially if you've bleached.
2. Capillary Botox & Shock Therapies (Genome Reconstruction): In-cabin masks holding ultra-potent microscopic molecules. Perfect for heavily dehydrated hair. Fills fiber gaps with humectant peptides and ingredients, redensifying hair "inside out", returning movement while terminating the scouring pad effect almost instantly.

A final tip upon returning from vacation: If your hair suffered major damage, avoid dyeing or bleaching right away. Give your mane a "chemical fast" spanning roughly 4 to 6 weeks. Fearlessly cut off that last centimeter of burned ends and allow salon treatments to work. Your hair will thank you, recovering all its life for the incoming season.
