Hairstylists and dermatologists are cautioning against the habit of sleeping with wet hair, citing potential damage to both hair and skin. Experts warn that wet hair is more fragile and prone to breakage, which can lead to split ends and long-term damage. Additionally, a damp scalp can create an ideal environment for fungal growth, increasing the risk of conditions like seborrheic dermatitis or dandruff.
The moisture from wet hair can also transfer to pillowcases, potentially harboring bacteria and contributing to skin issues such as acne or eczema. To mitigate these risks, professionals recommend drying hair before bed, using leave-in conditioners, or loosely braiding damp hair to reduce friction and maintain scalp health.
Briana Delvecchio, a hairstylist from New York, emphasizes the importance of avoiding the habit and suggests a simple routine swap to keep hair, scalp, and skin healthy. Dr. Noah Gratch, a board-certified dermatologist, also agrees that while sleeping with wet hair is not dangerous, it can lead to various dermatologic and hair health concerns. Moisture trapped on the pillowcase can harbor bacteria, fungi, and dust mites, potentially contributing to acne flare-ups or exacerbating existing skin conditions like eczema.
Both professionals stress the importance of adopting practices that prevent moisture buildup, such as towel-drying hair before bed and using protective measures to ensure long-term scalp and skin health. These recommendations highlight the broader implications of personal grooming habits on overall well-being.
