3. Sleep on silk
Cotton pillowcases, while comfortable, are highly absorbent.
They can draw moisture away from your hair as you sleep. This loss of moisture not only dries out your hair but can also lead to frizz.
Silk and satin, on the other hand, are less absorbent. They help retain the natural oils in your hair and maintain its moisture balance, which is crucial for keeping frizz at bay.
They also have smoother surfaces compared to the relatively rough texture of cotton.
When you toss and turn during sleep, a cotton pillowcase can create friction against your hair, leading to hair cuticle damage, which results in frizz and tangles.
Silk and satin pillowcases allow your hair to glide over the pillow with minimal friction, thereby reducing the risk of frizz and breakages.
If you want your waves definition to last longer, then sleeping on silk is a game changer.
