Optimal Drying Distance & Heat Guide
Most heat damage isn't about the dryer — it's about how you hold it. Tell us about your hair and we'll show you the distance, heat and timing that protect it.

Your gentle-drying plan
A LeLunar hands-free dryer holds this distance and angle steady for you, so the airflow stays consistent while your hands stay free.
Educational guidance based on hair-science research — not medical advice. Estimates vary by individual. Informed by Lee et al. (2011) on dryer distance and motion, and keratin's ~150°C thermal threshold.

Hair drying distance & heat — FAQ
For most hair, about 15–20 cm — roughly a hand-span — with the dryer always moving. Research on dryer distance and motion found that drying at a sensible distance with continuous movement caused less surface change than holding heat close and still. Finer, colour-treated or high-porosity hair does better a little further back.
Lower than you think. Keratin starts to soften and become vulnerable around 150°C, so there's rarely a reason to use the hottest setting. A low-to-medium temperature with good airflow and movement dries efficiently while protecting the cuticle. Finishing on a cool shot helps the cuticle lie flat.
It depends on length, thickness and texture — anywhere from a few minutes for short fine hair to 25–30 minutes for long, thick or coily hair. The tool above estimates your range. Stopping a touch before bone-dry is gentler than blasting it fully dry.
Not necessarily. Very long air drying keeps the hair swollen with water for a long time, which can stress it too. Gentle, controlled blow drying — right distance, low heat, steady motion — is a reasonable middle ground for many hair types.
