Why you wake up with frizzy hair, and how to stop it

You go to bed with smooth, shiny hair. You wake up looking like you got caught in a mild storm. If this is your life, you're not alone, and the problem probably isn't your shampoo.

The real culprit

Frizz happens when the outer layer of each strand (the cuticle) lifts and lets moisture in unevenly. One of the biggest triggers is friction, and the place you get the most friction is your pillow, for hours, every night.

Five tiny changes

• Sleep with dry hair whenever you can. Wet hair is more fragile and frizzes more.
• Swap your pillowcase. A smooth silk surface means far less rubbing on the cuticle.
• Ditch tight elastics. They dent and snap hair. Try a silk scrunchie or a loose braid.
• Seal your ends with a drop of lightweight oil.
• Skip the morning brush-out if your hair has any texture. Smooth with your hands and a little cream instead.

Frizz isn't a hair type. Most of the time, it's friction.

What to expect

This isn't a 30-day transformation situation. Plenty of people notice a difference within the first few mornings: hair that looks more like it did the night before, and a lot less to fix before work.
