Caring for curly hair after summer: hydration, nutrition and essential care

Aug 29, 2025Safia A.

Goodbye summer, holidays, sun and beach…


Summer is almost over, and like many people, you've surely made the most of the season to swim and sunbathe. But have you thought about your hair?


After the joy of the summer holidays, it's back to reality: hair is often dried out by chlorine and lack of care, damaged by the sun and weighed down by impurities and excess sebum.


That's why today we're sharing all our tips and advice for getting radiant hair back after summer! ☀️



I. Why does curly hair suffer after summer?

To find solutions, you first need a good understanding of the problem!


It's therefore worth understanding why textured hair suffers so much after summer: 

Prolonged sun exposure: UV rays that weaken the hair fibre

Summer obviously means sun!

Although it brings us pleasant warmth and a radiant complexion, the sun is not textured hair’s best friend…

During this season, we spend more time exposed to the sun and the risks it brings:


  • Keratin oxidation: UV rays break down the proteins that make up the hair fiber, making hair more fragile and brittle.


  • Damaged cuticles: the scales lift, making the fiber porous and more vulnerable to aggressors.


  • Color loss: UV rays oxidize pigments (natural or artificial), causing fading, dullness and orange or yellow tones.


  • Dryness: UV rays destroy the hair's protective lipids, making it rough and dry. 

Sea salt and pool chlorine: dryness and loss of shine

Whether it's a swim in the sea or a dive into the pool, our hair never comes out unscathed…
Salt and chlorine considerably weaken the hair fibre and dull its natural shine:

  • Intense dehydration: salt and chlorine dry out the hair, increasing water loss and leaving the fiber rough and dull.

  • Cuticle damage: salt crystals and the chemical agents in chlorine lift the scales, making hair porous and vulnerable.

  • Loss of shine: the hair's surface becomes uneven, which prevents light from reflecting properly. The lengths therefore look dull.


  • Fading colour: chlorine alters hair pigments (especially on coloured or bleached hair), causing discolouration, unwanted tones and loss of intensity.

Wind and heat: more frizz and breakage

While summer means sunny days, it also brings intense heat and winds that put hair to the test:

Drying out of the fiber: heat speeds up the evaporation of the water in the hair, leaving it dry and dehydrated.


  • More frizz:wind lifts the cuticles and disrupts the structure of the fiber, which accentuates the “static hair” effect and makes hair difficult to manage.


  • Knots and tangles: gusts of wind cause strands to intertwine, which weakens the fiber and makes detangling harsher.


  • Increased risk of breakage: combined, heat and wind weaken keratin, making hair more brittle and more prone to split ends.



👉 All these factors affect textured hair even more. Curls therefore need a hydrating and nourishing ritual after summer.

II. Hydrating deeply to restore suppleness

It's no secret: dry hair needs hydration. And after being exposed to the sun all summer, this step is all the more important!

The importance of hydration after sun exposure

Giving your hair good hydration will help it regain its radiance, shine and softness.


In practical terms, hydration helps to:


  • Restore lost water: it gives hair back its suppleness and elasticity.


  • Repair the fiber: hydrating treatments fill in sensitized areas, strengthening resistance to breakage.


  • Limit frizz: well-hydrated hair keeps a smooth cuticle and is easier to manage.


  • Preserve shine: hydration smooths the hair surface, which reflects light better.


  • Get ready for back-to-school season: after summer, deep hydration helps restore healthy, radiant hair.

Use a gentle, nourishing shampoo to wash without harshness

Good hydration always starts with using the right shampoo!

Indeed, not all shampoos are sufficiently hydrating. It is important to know how to recognize which shampoo can give you the hydration your hair needs.

So, how do you choose the right shampoo?

The first step is to identify the hydrating active ingredients: Aloe Vera and Glycerin are perfect for this. They are humectants, which means they attract water, making them very effective for hydration.

So choose treatments that contain it!

And of course, for curly hair, you'll also need to turn to effective actives to define curls.

The ideal choice: Jia Paris Nourishing Shampoo

In addition to Aloe Vera and Glycerin, this Hydrating Shampoo also contains Pequi Oil, which nourishes, defines curls and reduces frizz, as well as Jojoba oil, which protects, prevents hair dehydration and enhances shine.

Formulated without sulfates or silicones, it deeply hydrates and nourishes the hair fibres and defines curls from the washing step, without weighing them down!

🌟 Its little extra: Its rich, light lather, for a pleasant washing experience. 

Add a hydrating leave-in treatment to maintain hydration day to day

Using a Hydrating Shampoo is not enough. It is essential to complete your routine with hydrating styling products designed for textured hair.

Leave-in treatments let you care for your lengths after washing, ensuring long-lasting hydration.

At Jia Paris, we offer 3 leave-in treatmentsto meet the needs of different textured hair types.

  • For fine curly hair, opt for the Hair Milk: made with Aloe Vera, Glycerin and many nourishing and hydrating oils and butters (Pequi, Macadamia, Castor, Shea), it deeply hydrates the lengths without weighing hair down.


  • If you have thick hair, go for the Nourishing Smoothie: Its light, airy, almost mousse-like texture coats each curl without weighing it down while providing long-lasting hydration.


The Leave-In Conditioner is designed for coily and afro-textured hair, but it can be used on curly hair as a repairing treatment before a protective style! 

III. Nourish intensely to repair the fiber

Why nourishment is essential after summer

After weeks of exposure to sun, salt or chlorine, the hair fiber is weakened, dried out and lacks suppleness.

Nourishment then comes in to deeply strengthen and repair, providing the lipids needed to restore the hair's natural protective barrier. It is a key step to get strong, shiny, resilient curls back.

Weekly application of a rich mask to restore curls

A nourishing mask is essential to restore damaged curls after summer. Used once a week, it delivers a concentrated dose of nourishment that repairs the fibre and restores elasticity and softness.

Choose a mask rich in nourishing plant oils and butters! 

Recommendation: the Jia Paris Intensive Nourishing Mask

It's the ideal treatment to restore vitality to dry, brittle and damaged hair.

With a formula made up of 97.6% natural ingredients, it contains 5 natural plant oils and butters: Shea, Olive, Castor, Coconut and Macadamia. This mask provides intense, lasting nourishment without weighing hair down. 

💡 Tip: seal in hydration with a serum for more definition

After hydrating and nourishing your hair, remember to seal in the hydration with a serum. This step keeps water locked into the core of the fibre, while boosting shine and curl definition.

The Jia Paris Curl Defining Serumis enriched with natural oils such as Pequi and Macadamia Oil, which shape and deeply nourish, Soybean Oil, which strengthens the hair fiber, and Jojoba Oil, which prevents dehydration and adds shine. 



VI. The right habits to adopt all year round

To preserve the health and beauty of your curls, a few simple everyday habits can make all the difference:

  • Sleep on a satin pillowcase: this material reduces friction during the night, limits breakage and prevents frizz.


  • Use heated tools less often: hair dryers, straighteners and curling irons weaken the hair fibre. By using them in moderation, you preserve your hair's elasticity and vitality.

  • Set up a stable routine: choosing suitable products, rich in hydrating and nourishing active ingredients, is essential to keep curly hair balanced all year round.



Conclusion:

After summer, your curly hair deserves special attention to regain all its vitality. By combining hydration, nourishment and good daily habits, you ensure supple, defined and radiant curls all year round.
