Uncombed means hair that hasn't been brushed or neatly arranged. When you wake up in the morning with your hair sticking out in different directions, tangled and messy, that's uncombed hair.

The word describes the wild, natural state hair falls into when you don't run a comb or brush through it. Maybe you overslept and had to rush to school, or you were so absorbed in building something that you forgot to check a mirror. Uncombed hair might have knots, stick up at odd angles, or look generally disheveled.

You'll sometimes see uncombed used to describe other things that look similarly untidy or ungroomed, like an uncombed beard or even, more poetically, uncombed grass blowing wildly in a field. The word captures that untamed, natural messiness that appears when something hasn't received careful attention.
