Yes, you can curl dirty hair, and in fact, it often holds curls better than freshly washed hair. Many sources confirm that slightly dirty or second-day hair provides better grip and texture for curls to last longer.
Why Dirty Hair Holds Curls Better
Several reasons explain why dirty hair holds curls more effectively:
- Natural Oils: The oils produced by your scalp (sebum) provide a natural hold, giving the hair more texture and grip for the curl to cling to. Squeaky-clean hair lacks this natural hold.
- Improved Texture: The build-up of natural oils and products from previous days adds texture, providing a better surface for the curl to adhere to.
- Less Slip: Clean hair tends to be more slippery, causing curls to fall out more easily. The oils and product build-up in dirty hair create friction, helping the curl stay in place.
