Do you go to bed with beautiful, well-defined curls, only to wake up with flat, tangled, or frizzy hair? In summer, this phenomenon is even more common. Heat, humidity, nighttime perspiration, and rubbing against the pillow can quickly alter the shape of your curls.
However, a few simple steps can help preserve the definition of curly hair overnight and minimize touch-ups in the morning.
In this article, discover how to protect your curls while you sleep, which hairstyles to favor, and which products to use to keep your hair soft, hydrated, and well-defined throughout the summer.
Why do curly hair suffer more overnight?
Curly hair is naturally more fragile than straight hair.
Their spiral shape makes the hair fiber more sensitive to:
- dehydration;
- friction;
- breakage;
- tangles;
- frizz.
During the night, repeated head movements against the pillow can lift the hair cuticles and disrupt the natural definition of curls.
In summer, perspiration and humidity often exacerbate this phenomenon.
The effects of summer heat on curls during sleep
Increased perspiration
When temperatures rise, the scalp sweats more during the night.
This moisture can:
- relax curls;
- promote frizz;
- accentuate the fluffy effect;
- make roots heavier.
Curly hair then becomes more difficult to restyle in the morning.
Accelerated hydration loss
The hot, dry air of some summer nights can also promote the evaporation of water from the hair fiber.
Hair gradually becomes:
- drier;
- less supple;
- duller;
- more brittle.
Why protect your curly hair overnight?
Good nighttime protection helps to:
- preserve curl definition;
- reduce frizz;
- limit tangles;
- decrease breakage;
- maintain hydration longer.
By adopting a few simple habits, you can significantly reduce the time spent styling your hair in the morning.
The ideal hairstyle for sleeping with curly hair
The "pineapple," the preferred technique for curly hair
The "pineapple" consists of tying hair very high on the head with a soft elastic band or a satin scrunchie.
This technique helps to:
- protect the lengths;
- prevent curls from being flattened;
- maintain more volume;
- reduce friction.
It is particularly suitable for curly, coily, and kinky hair.
Loose braids
For long hair, one or two loose braids can also be a good solution.
They help to:
- limit tangles;
- reduce friction;
- protect the ends.
Be careful not to tie them too tightly to avoid breaking the curls.
Protective twists
Twists are particularly popular for textured hair.
They help to:
- maintain hydration;
- limit breakage;
- make it easier to reshape curls in the morning.
Satin or cotton: what impact on curls?
Why does cotton promote frizz?
Cotton pillowcases naturally absorb some of the hair's moisture.
They also create more friction.
Result:
- hair dries out faster;
- curls lose their definition;
- frizz increases.
The benefits of satin
Satin allows hair to glide more easily during the night.
It helps to:
- preserve hydration;
- reduce friction;
- protect curl definition;
- limit breakage.
A satin pillowcase or bonnet is often one of the best investments for curly hair.
Should you apply a treatment before bed?
It all depends on your hair's needs.
For dry or dehydrated hair
A small amount of leave-in treatment can help maintain hydration overnight.
Shaeri's Daily Treatment is particularly suitable for this use.
It helps to:
- hydrate the lengths;
- reduce frizz;
- improve suppleness;
- restore curl definition.
For very dry ends
A few drops of Shaeri's Hair Oil applied to the ends before bed can limit nighttime dehydration.
Thanks to its blend of five vegetable oils, it helps to:
- nourish the hair fiber;
- protect the lengths;
- reduce breakage;
- improve shine.
How to refresh your curls in the morning?
Even with an excellent nighttime routine, some curls may lose a little definition.
To easily revive them:
- lightly dampen the lengths;
- apply a small amount of leave-in treatment;
- reshape the curls with your fingers;
- let them air dry naturally.
This method generally allows you to quickly regain bouncy curls without having to redo your entire routine.
Mistakes that damage curls overnight
Sleeping with hair down
Hair rubs more against the pillow, which promotes tangles and frizz.
Using overly tight elastic bands
They can break hair and create marks in curls.
Going to bed with very wet hair
Prolonged humidity weakens the hair fiber and promotes tangles.
It is best to let hair dry at least partially before bed.
Neglecting hydration
Already dehydrated hair will be much harder to preserve overnight.
