Does sleeping with a towel on the pillow help my skin?

If you look at videos titled "Great Tips for Improving Your Skin"

I heard that it helps to make sure to put a towel on the pillow before sleeping.

But I wash my hair thoroughly every evening before going to bed.

I'm curious what sleeping with a towel on the pillow has to do with improving my skin.

By any chance, are there any of you who sleep with a towel on your pillow and have experienced improved skin?!

If even one person does, I should put it into practice right away, too.
