Have you ever gone to bed with dripping wet hair and wondered whether you were secretly doing damage to your strands? Maybe causing them to thin, or even fall out?
If you're the type of person that showers at night, throws on your pajamas and hops right into bed, you might want to take the extra time to dry it first.
"Sleeping with wet hair doesn't do any particular damage to the hair shafts themselves, but it does make it more likely your hair could be flat, frizzy or generally dull-looking when you wake up," Jessica J. Krant, a cosmetic and medical dermatologist at the Laser & Skin Surgery Center of New York, said in an interview.
Krant explained the outer layer of each hair shaft, or cuticles, are like roof shingles, scaling up in one direction. "When hair is blow dried with gentle smoothing, the shingles all lie flat — as long as there isn't too much heat damage over time from overstyling," she said. When you fall asleep with wet hair, the hairs often press and rub against the pillow case, leaving the cuticles at different angles, and thereby "reducing the reflective shine and seal of any given shaft and making it seem dirtier."
