Isn't that something a lot of people get, even with natural hair?
Hence the expression "Bed-Head hair" !!!
The usual advice is to use satin/silk pillow cases as they are less rough on the hair.
Or you start wearing a hair net to bed.
It may be the result of the hair products you're using, but very few people wake up with great looking hair.
A quick spritz with a leave-in conditioner each morning should revitalise the hair and allow you to re-groom it.
