Towels tend to snag hair, especially curly hair, and can even leave behind annoying lint. Instead, try using a smooth surface cloth such as a cotton t-shirt, pillowcase, or even boxer shorts. These alternatives are much safer for your hair, but remember to only blot gently and never vigorously rub your hair and scalp.
The best way to prevent your hair from snagging on something (which can cause tangles and split-ends) while you sleep is by piling it on the top of your head in a loose bun or ponytail and then sleeping on a satin pillowcase. For even more protection, you can wrap your hair with a satin or silk scarf.
If you do not want to wrap your hair at night with a scarf, a satin pillowcase is the healthiest choice for your hair while you sleep. The smooth satin won’t snag your hair, and it will also help your hair retain moisture. As an added bonus, a satin pillowcase is also healthier for your face because it helps the skin retain moisture as well and reduces facial creasing.
