Health and hair care experts have long warned against daily habits that can negatively affect scalp health and hair quality. One habit that has stirred much debate among both professionals and the public is sleeping with wet hair.

Dr. Saurabh Sethi, a Harvard-trained physician, issued a warning about this practice, emphasizing its potential to cause hair loss and even baldness over time. In a video shared on TikTok and Instagram, Dr. Sethi explained that moisture on the scalp creates an ideal environment for the growth of fungi and bacteria, which can lead to dandruff or seborrheic dermatitis—conditions that cause itching and flaking.
He further noted that sleeping with damp hair weakens hair strands, making them more prone to breakage, and can contribute to other scalp-related issues. According to Dr. Sethi—who has over 1.1 million Instagram followers—the friction from tossing and turning during sleep places added stress on wet hair, leading to tangling, thinning, and frizz.
To mitigate these risks, he strongly recommended drying your hair before bed, even if it’s just a quick blow-dry, stating that such a step can make a significant difference in hair health.
His video prompted widespread engagement, with many viewers sharing personal stories—such as dealing with bad odors from sleeping with wet hair—and confirming they had abandoned the habit after watching his advice.
Beyond hair loss, experts also warned that going to bed with wet hair may trigger skin problems, like acne, especially if you're sleeping on a damp pillow or one contaminated with hair product residues. This creates a moist, oily environment that clogs pores and promotes inflammation.
Experts recommend keeping your hair clean, dry, and away from the face during sleep to minimize these risks to both skin and hair health.
