Sleeping with wet hair is generally not recommended as it can lead to hair and scalp issues. Experts highlight five main reasons why it’s advisable to dry your hair before bed:
1. **Hair breakage**: Wet hair is more vulnerable to breakage due to increased friction with bedding fabrics.
2. **Scalp microbiome disruption**: The combination of sweat, sebum, and product buildup can disrupt the scalp microbiome, affecting hair growth and follicle health.
3. **Increased bacteria growth**: Damp pillows and bedding create a breeding ground for bacteria, leading to scalp concerns such as breakouts and scalp acne.
4. **Scalp infections**: Folliculitis or seborrheic dermatitis can worsen due to the warm, moist conditions created by wet hair.
5. **Exacerbation of dandruff, psoriasis, and eczema**: Sleeping with wet hair can exacerbate these conditions.
