When we sleep, we move around. We switch from side to side, move our arms, and rub our heads on the pillow.

All of this messes up our hair. And especially straight hair. That’s why straight hair is often tangled when we wake up.

Here’s how to avoid that, whether you have straightened your curly hair or have naturally straight hair.

How to Sleep With Straight Hair

How to Sleep With Straight Hair

When sleeping with straight hair, it’s all about keeping it in place. You need to minimize the chance of it tangling and frizzing when you move around.

So here’s how to keep hair straight while sleeping:

  1. Straighten before sleeping
  2. Use a silk pillowcase
  3. Brush and wrap your hair
  4. Use a little hair oil or serum
  5. Avoid an overly humid room
  6. Part your hair before sleeping
  7. Always condition
  8. Avoid hair ties
  9. Use a silk scarf
  10. Use dry shampoo between washes

1. Straighten Before Sleeping

Ensure your hair is completely dry and straightened using a straightener with ceramic plates. Gently towel-dry your hair and use a paddle brush while blow-drying it.

2. Use a Silk Pillowcase

Switch to a silk pillowcase. This reduces friction against your hair, resulting in less frizz and keeping your hair straight.

3. Brush and Wrap Your Hair

Before bed, brush your hair and wrap it around your head. This helps maintain straightness while you sleep.

4. Use a Little Hair Oil or Serum

Apply a straightening serum or hair oil to protect your hair from heat and maintain smoothness.

5. Avoid an Overly Humid Room

Control your room’s humidity, as excessive humidity can cause frizz and damage straightened hair.

6. Part Your Hair Before Sleeping

Part your hair into two sections and gently comb it for better stability during sleep.

7. Always Condition

Condition your hair every time you wash it, as this helps keep it smooth and manageable.

8. Avoid Hair Ties

Do not use hair ties while sleeping since they can cause kinks and creases in your straightened hair.

9. Use a Silk Scarf

Wrap your hair in a silk scarf before bed – the scarf will help maintain straightness and reduce friction.

10. Use Dry Shampoo Between Washes

If needed, use dry shampoo between washes to keep your hair looking fresh and avoid excessive washing, which could damage straightened hair.

Best Way to Wrap Your Hair to Keep It Straight

To keep your hair straight overnight, the best way to wrap it is by using a silk or satin scarf. These materials are smooth and help reduce friction between your hair and bedding. This prevents frizzy ends and helps preserve the straightness of your hair while you sleep.

To wrap your hair before sleeping, follow these steps:

  1. Brush your hair: Gently brush your straightened hair to remove any tangles or knots. This will make the wrapping process easier and ensure your hair stays smooth.
  2. Fold the scarf: Take a large square silk or satin scarf and fold it into a triangle. If you don’t have a square scarf, you can also use a long rectangular one – just make sure it’s wide enough to cover your entire head.
  3. Position the scarf: Hold the folded scarf behind your head with the long edge at the nape of your neck. The point of the triangle (or the middle of the rectangular scarf) should be hanging down your back.
  4. Wrap your hair: Starting from one side of your head, begin wrapping your hair around your head in a circular motion. Try to keep your hair flat and smooth as you wrap it. Continue to wrap your hair until you reach the other side of your head.
  5. Tie the scarf: Once your hair is wrapped, bring the two ends of the scarf to the front of your head, above your forehead. Tie them together in a secure but comfortable knot or bow.
  6. Adjust if needed: If your scarf feels too loose or tight, or if any hair escapes the wrap, don’t hesitate to adjust it as needed. The goal is to have your hair safely tucked in and secure, without causing any discomfort.

Remember, it’s essential to use a silk or satin scarf for this method because these materials are gentle on your hair and won’t cause breakage or frizz. By following these steps, your straightened hair should remain sleek and smooth when you wake up the next morning.

Product Hacks to Keep Your Hair Straight

Product Hacks to Keep Your Hair Straight

If you don’t want to wrap your hair, and the other techniques don’t work for you, you can use products to help you.

Here are the best products to keep your hair straight overnight.

Clarifying Shampoo

To keep your hair straight overnight, start by using a clarifying shampoo. This type of shampoo removes dirt and buildup, helping your hair lie flat.

Additionally, on days when you don’t wash your hair, consider using a dry shampoo to keep your straight hair fresh and clean. Dry shampoo absorbs oils that may cause your hair to look messy or greasy.


After shampooing, use a conditioner, specifically a leave-in conditioner with keratin protein. Keratin protein helps strengthen and straighten your hair while adding moisture.

Don’t skip this step, as conditioning is essential in keeping your hair smooth and manageable. Remember to use a conditioner that adds moisture and avoids weighing your hair down.


Before going to bed, apply an overnight protecting serum to your hair. Look for a product with high protein levels and a low amount of alcohol.

This type of serum shields your hair against heat and damage from straightening or drying tools. A thermal protectant can also be used for longer-lasting results.

Applying a serum or protectant helps ensure your hair stays smooth, reducing the likelihood of frizziness or curls forming while you sleep.
