When it comes to cleansing your hair, people tend to fall into two camps: those who do it in the morning and those who prefer washing hair at night. And once you've settled into one routine, you rarely switch. This article is for the evening washers, especially those who go to bed with damp hair—a habit that can be harmful to hair health, despite once being considered trendy.

Even Caroline de Maigret once shared that she did it for the tousled effect, but dermatologist Clara Lacasta, from IMR, warns against it: "Wet hair is a breeding ground for dermatitis and potential fungal infections. It’s also at its weakest when wet, making it prone to breakage." Dr Lacasta also clears up another common misconception: washing hair daily won’t cause it to fall out.

In fact, if your hair gets greasy or dirty frequently, it’s perfectly fine to wash it daily. Regular washing can actually be beneficial, as each wash is an opportunity to nourish hair with conditioner and oils, particularly on the ends. Blow-drying tips for healthier hair If you’re washing hair at night, blow-drying becomes essential to avoid dampness.

However, even during the day, proper blow-drying can prevent issues, as damp hair in any setting can weaken strands. Dr Lacasta recommends using a hair dryer to dry hair almost completely. Use a round brush at the end if you want to add shape, but avoid using it throughout to minimize breakage.
