context: When I woke up in the morning I noticed that my hair was not looking very clean. It was time to have a shower and wash my hair. I turned on the water in the shower and waited for it to heat up. Then I stepped in and started to wet my hair. When my hair was completely wet I reached for the shampoo bottle and squeezed a small amount into my hand. Then I rubbed this shampoo into every part of my hair. I scrubbed and scrubbed allowing the bubbles to get really big. Then it was time to make my hair really clean. I let the water run all the way over my hair and I kept pushing it through until I could feel that my hair was squeaky clean. I turned the water off. My hair was now clean. I found a towel and wrapped it around my head so that my hair could dry. When I had gotten dressed I used the hairdryer to completely dry my hair. Now when I looked in the mirror my hair was shiny and sparkling. It was perfectly clean.
question: Did they wash their hair because it was dirty?
reference: Yes
candidate: Yes, shampoo had to be put into every part of a hair
