Ever washed your hair in the evening, skipped the blow-dryer, and gone to bed with damp strands? As trichologists with over a decade of experience helping clients maintain healthy locks, we've seen the effects firsthand—and yes, it can harm your hair.
Wet hair is far more fragile and brittle than dry hair, making it prone to breakage from pillow friction during sleep. The risk is higher near the roots. To protect it, at least towel-dry the top layers before bed to reduce snapping. For added benefit, form a loose braid (keep the elastic gentle)—wake up to soft waves without the damage.
