Summer is a particularly demanding season for curly, coily, and kinky hair. Between the sun, swimming, heat, wind, and humidity, curls are constantly exposed to aggressions that can quickly alter their definition and health.
Hair becomes drier, frizz appears, ends become brittle, and curls sometimes lose their natural bounce. However, with an adapted routine, it is entirely possible to maintain soft, shiny, and perfectly defined hair throughout the summer.
In this comprehensive guide, discover how to care for your curly hair during the summer season, which treatments to prioritize, and what habits to adopt to durably protect your hair.

Why is curly hair more fragile in summer?
Curly hair has a naturally more vulnerable structure to external aggressions.
The spiral shape of the hair fiber makes sebum circulation more difficult from roots to ends. As a result, the lengths are often drier and more fragile than straight hair.
During summer, this particularity is accentuated by several factors:
- UV rays;
- chlorine;
- sea water;
- high temperatures;
- wind;
- more frequent washing.
This combination promotes dehydration and increases the risk of breakage.
The main needs of curly hair in summer
To maintain beautiful curls throughout the season, three needs must be at the heart of your routine.
Preserve hydration
Hydration remains the absolute priority for curly hair in summer.
A dehydrated fiber quickly becomes:
- dull;
- rough;
- difficult to style;
- prone to frizz.
Nourish the lengths
Hydration alone is not enough.
Curly hair also needs nourishment to limit water loss and strengthen its natural protective barrier.
Vegetable oils play an essential role here.
Protect hair from summer aggressions
Sun, salt, and chlorine progressively weaken the hair fiber.
The goal of the summer routine is therefore also preventive: to protect hair before it gets damaged.
How to build a curly hair routine in summer?
An effective routine relies on a few key steps that help maintain hair balance throughout the season.
Step 1: nourish with an oil bath before shampooing
The oil bath is one of the best allies for curly hair during summer.
Before shampooing, it helps to:
- strengthen the hair fiber;
- limit dehydration;
- improve suppleness;
- protect the lengths.
Shaeri Hair Oil combines five complementary vegetable oils known for their nourishing and regenerating properties.
It can be used:
- as an oil bath;
- before sun exposure;
- before swimming;
- on dry ends.
A few applications per week are enough to preserve the quality of the curls.
Step 2: cleanse without drying
In summer, it can be tempting to shampoo more often.
However, overly aggressive washing can accentuate dehydration.
Shaeri Nourishing Shampoo helps to:
- gently cleanse the scalp;
- preserve natural hydration;
- nourish the lengths;
- maintain hair suppleness.
Its sulfate-free formula respects the balance of textured hair.
Step 3: hydrate and detangle with a nourishing mask
Curly hair particularly appreciates rich treatments after sun exposure or after swimming.
Shaeri Intense Mask Treatment helps to:
- deeply nourish;
- facilitate detangling;
- strengthen the hair fiber;
- limit frizz.
Used once or twice a week, it helps maintain soft and bouncy curls.
Step 4: protect curls daily
Leave-in treatment is often the preferred step for curly hair.
Shaeri Daily Treatment notably helps to:
- rehydrate the lengths;
- redefine curls;
- reduce frizz;
- protect hair from humidity.
It can be used on both damp and dry hair.
How to protect your curly hair at the beach and pool?
Swimming is one of the main sources of dehydration during summer.
A few simple gestures can limit damage.
Before swimming
Before entering the water:
- wet your hair with clear water;
- apply a few drops of oil to the lengths;
- tie up hair if possible.
This preparation reduces the absorption of salty or chlorinated water.
After swimming
After each swim:
- rinse hair quickly;
- apply a moisturizing treatment if necessary;
- avoid leaving salt or chlorine on the fiber for several hours.
These simple gestures help to durably preserve curls.
The best protective hairstyles for summer
Protective hairstyles help limit friction and exposure of the lengths.
Among the most effective:
- braids;
- twists;
- low buns;
- plaits;
- braided buns.
They allow you to:
- maintain hydration;
- reduce breakage;
- limit tangles;
- protect the ends.
How to know if your curly hair lacks hydration?
Certain signs are unmistakable.
Dehydrated hair often shows:
- more frizz;
- a loss of definition;
- a rough feel;
- less shine;
- more breakage.
It is important to distinguish between dry hair and dehydrated hair to provide appropriate care.
A simplified routine for holidays
When traveling, it's not necessary to bring a dozen products.
A minimalist routine can be perfectly sufficient:
- a multi-purpose oil;
- a mild shampoo;
- a moisturizing leave-in treatment;
- a nourishing mask.
This approach allows you to travel light while caring for your curls.
Mistakes that damage curly hair in summer
Certain habits can compromise all efforts made.
Neglecting sun protection
Sun is one of the main causes of hair dehydration.
Forgetting the ends
The ends are always the first to suffer from summer aggressions.
Using aggressive shampoos too often
Too frequent or too harsh washing weakens the hair fiber.
Waiting until autumn to repair
Prevention is always more effective than repairing damaged hair after several weeks of exposure.
