Why you shouldn't sleep with wet hair!
There is unfortunately bad news when it comes to sleeping with wet hair:
Hair is EXTREMLY fragile when wet & it is more likely to get damaged overnight if you don't dry it properly.
You are also at risk to FUNGAL infections of the scalp which leads to dandruff or dematitis.
Not to mention the massive HEADACHE some of us wake up with the following day.
So in CONCLUSION, it is best to dry your hair entirely before you go to bed.
