Cutting hair with kitchen scissors is generally harmful because these scissors have blunt, wide blades not designed for clean haircuts. Using them can cause split ends, uneven cuts, and hair damage. Specialized hairdressing scissors, like those recommended by hair professionals and companies focused on precision cutting, ensure cleaner cuts and healthier hair. While kitchen scissors may be used in emergencies with caution, investing in proper hair cutting tools is best for maintaining hair health and achieving professional results.
