Summer Hair Care: Tips for Maintaining Healthy and Beautiful Hair

Summer is synonymous with the beach, the pool, and long days outdoors. But while we are enjoying the sun and the water, our hair suffers in silence. Solar radiation, pool chlorine, and ocean salt are the three great enemies of healthy hair during the hotter months. And the worst part is that, more often than not, we don’t notice the accumulated damage until it’s already too late.

The good news is that with a few simple habits and a little attention, you can protect your hair and make it to the end of summer with locks as beautiful as day one. In this guide, we’ll tell you everything you need to know about summer hair care, complete with practical tips you can start using right now. Because rocking well-cared-for hair is the perfect complement to your favorite bikini or your go-to swimsuit.

During the summer season, your hair faces a combination of aggressions that don’t occur the rest of the year. Understanding exactly what happens will help you make better choices when it comes to taking care of it.

• Ultraviolet radiation is probably the most damaging factor. UVA and UVB rays weaken keratin, which is the main protein that makes up the hair fiber. The result is hair that loses its shine, becomes more fragile, and tends to break easily. If your hair is dyed or bleached, the effect is even more noticeable: the pigments oxidize, and the color fades much faster.
• Pool chlorine is another major aggressor. This chemical substance dries out the hair cuticle and can alter its toneespecially in blondes and light highlights, where those unwanted greenish tints sometimes appear. Furthermore, chlorine irritates the scalp and, for people prone to hair loss, can make the situation worse.
• As for ocean salt, even though many of us love the beach waves effect it leaves behind, it acts as a powerful natural dehydrator. It extracts water from the inside of the hair fiber, leaving it dry, rough, and difficult to manage. If we don’t rinse our hair after swimming, the salt crystals stick to it and continue to damage the hair for hours.
• To top it all off, we have to add frequent washing, which strips away the natural oils that protect the scalp, and the wind, which promotes tangles and split ends. All together, it is an aggressive cocktail that deserves just as much attention as summer skincare.

Just as you wouldn’t step outside without sunscreen on your skin, your hair also needs a barrier against UV rays. There are sprays and oils with UV hair filters that you apply before sun exposure to help preserve hydration and colour. Ideally, reapply after each swim.

If you don’t have a specific product to hand, a great alternative is to use accessories such as hats, wide-brimmed hats, or headscarves. Besides protecting your scalp from sunburn, they reduce direct exposure of the hair fibre to the sun. And as a bonus, they’re the perfect accessory to complete your beach look. At Roidal, our beach accessories collection is designed precisely for that: style and protection in a single garment. From versatile sarongs you can use as a turban to elegant beach dresses that cover your shoulders and hair from direct sunlight.

This is one of the simplest yet most effective habits. After swimming in the pool or the sea, rinse your hair with fresh water as soon as possible. This way, you remove chlorine or salt residue before it has time to penetrate the hair fibre and cause damage.

An extra trick: wet your hair with fresh water before getting into the pool or the sea. Since it’s already saturated with clean water, it will absorb less chlorinated or salty water. It’s a very simple step that makes a noticeable difference, much like washing your bikinis properly extends their lifespan.

Hydration is the key to counteracting the effects of summer on your hair. Add a nourishing mask to your routine once or twice a week, paying special attention to the ends, which are the most damaged area.

Products with ingredients like argan oil, coconut oil, or shea butter are especially effective at nourishing and repairing damaged hair fibres. Apply them after washing, leave them on for a few minutes, and rinse thoroughly. You’ll notice the difference from the very first application.

Frequent washing in summer is almost unavoidable, but you can minimize its impact by choosing a gentle shampoo, preferably sulphate-free. Sulphates are harsh detergents that strip the natural oils from the scalp, which worsens the dryness already caused by the sun and water.

A gentle shampoo will cleanse your hair without stripping its natural protection, and combined with a good conditioner, it will keep your hair manageable and shiny throughout the season. The same philosophy of caring for what you use every day applies to your swimwear: high-quality fabrics resist chlorine and salt better, just as a good shampoo protects your hair better.

Blow dryers, flat irons, and curling irons subject your hair to very high temperatures that damage the hair fibre. In summer, when your hair is already more exposed than usual, it’s best to keep its use to a minimum. Take advantage of the good weather and let your hair air dry, embracing its natural texture.

If you do need to use a heat styling tool, always apply a heat protectant beforehand. It’s an extra layer of defence that can prevent considerable damage.

When hair is wet, it’s much more elastic and vulnerable. Tugging and rough brushing can easily break the fibre. Always use a wide-tooth comb and detangle from the ends upwards, gently and patiently. A little leave-in conditioner before combing makes things much easier.

Summer hair care isn’t limited to what you apply on the outside. What you eat also directly affects the health of your hair. A balanced diet, rich in certain nutrients, can strengthen the hair fibre from within and make it more resistant to external aggressions.

Proteins are essential, since keratin, the main component of hair, is synthesized from amino acids. Including foods such as eggs, fish, legumes, and nuts in your diet will help keep your hair strong and full of body.

B vitamins, especially biotin (B7), are vital for hair growth and health. You’ll find them in whole grains, leafy greens, eggs, and dairy products. Vitamin E, on the other hand, acts as an antioxidant and improves circulation in the scalp; it’s found in nuts, avocado, and vegetable oils.

Iron and zinc also play an important role. Iron promotes oxygenation of the hair follicle and is found in lean meats, spinach, and legumes. Zinc contributes to the repair of hair tissue and is present in shellfish, seeds, and meats.

And of course, don’t forget about hydration. Drinking enough water throughout the day is the foundation of everything: good internal hydration is directly reflected in hair that is more flexible, shinier, and less prone to breakage.

Knowing what to do is just as important as knowing what to avoid. There are certain habits that, although they seem harmless, may be damaging your hair without you even realizing it. The same happens with swimwear: there are common mistakes when buying a swimsuit that are worth knowing about to avoid them. Here’s what we recommend you avoid doing with your hair if you truly want to keep it healthy:

• Tying wet hair with an elastic band is one of the most common mistakes. When hair is damp and held tightly, the band can weaken it and cause breakage in the same spot. If you need to tie your hair up after a swim, opt for soft clips or fabric scrunchies.
• Neglecting the ends is another common oversight. The ends are the oldest part of the hair and therefore the most vulnerable. Applying a protective serum or oil to the ends before sun exposure can prevent them from splitting and drying out.
• Brushing dry hair after the beach without first rinsing out the salt is a mistake that amplifies the damage. Salt crystals act like sandpaper on the hair fibre, and brushing only makes things worse. Always rinse first.
• Colouring or bleaching your hair just before the holidays is also inadvisable. Freshly coloured hair is more sensitive to the sun and chlorine, so it fades more quickly. If you’re planning a colour change, do it at least two weeks in advance and boost your hydration routine before any exposure.

Following a simple but consistent routine can make a huge difference in the state of your hair by the end of summer. Here’s an easy-to-follow plan:

Monday and Thursday: wash with a gentle sulphate-free shampoo, followed by a hydrating conditioner. Apply from mid-lengths to ends and leave on for at least two minutes before rinsing.

Wednesday or Saturday: intensive nourishing mask. Leave it on for 10 to 15 minutes with your hair wrapped in a warm towel to boost the absorption of the active ingredients.

Every day: before heading out, apply a hair sunscreen or an oil with UV filters, especially if you’ll be spending time outdoors. After every swim in the pool or sea, rinse with fresh water.

Before bed: if your hair tends to tangle, put it in a loose braid. This will prevent unnecessary knots and friction against the pillow.

This routine is a guideline, and you can adapt it to your hair type and needs. The key is consistency: well-cared-for hair in summer is hair that will reach autumn strong, shiny, and without the need for an emergency cut. Just as storing your bikinis properly ensures they’ll be in perfect condition for the next season, a good hair care routine protects your hair in the long run.

Beyond hair products, accessories are great allies for protecting your hair from the sun. And the best part is that, besides being functional, they add a touch of style to your beach look.

Wide-brimmed hats and floppy sun hats are the most classic and effective option. They protect both the scalp and the hair fibre from direct radiation, and they pair perfectly with any elegant swimsuit or printed bikini. A good hat is an investment in both health and style.

Headscarves and turbans are another very versatile alternative. You can use them to cover your hair while sunbathing and then transform them into a fashion accessory for the rest of the day. In fact, a Roidal sarong can double as a turban or headscarf, making it an essential multi-purpose piece in your beach bag.

Summer hair care doesn’t end when September arrives. In fact, the weeks after summer are crucial for repairing accumulated damage and restoring your hair to its optimal condition. Just as we dedicate time to post-summer skin care, your hair deserves that same post-summer attention.

Increase the frequency of hydrating masks to twice a week during the first weeks of autumn. If the ends are badly damaged, consider a trim to remove the most deteriorated areas and allow your hair to grow healthily from the root.

Incorporate a repair treatment with proteins or keratin to reinforce the internal structure of the hair fibre. And continue maintaining a diet rich in vitamins and minerals that support your hair’s natural recovery.

Ultimately, summer hair care follows the same logic as any other aspect of summer wellbeing: protect, hydrate, and nourish. If you already apply sunscreen every day and care for your skin after sun exposure, it makes perfect sense to do the same for your hair.
