The curved blow-drying brush is curved like the roundness of the head, with air slats for faster blow-drying. The brush has 50 flexible spikes that help with detangling both before and during blow-drying. On the brush there are also 10 rows of wild boar hair that smooth and add shine to the hair during blow-drying. With the brush's carefully designed spikes and rounding, it massages the scalp during detangling and blow-drying. Application: Can be used on wet & dry hair. Cleaning: It is strongly advised not to use strong chemicals to clean the brush. To clean the brush, wash it in lukewarm water with a little shampoo, rinse and let the brush dry naturally. It is not recommended to use heat to dry the brush, nor to soak the brush for a long time. Possibly. Spray antibacterial spray on to disinfect.
