Here's why:
* Sharp scissors create clean, precise cuts: Dull scissors can cause split ends, uneven cuts, and even snags or breakage.
* Sharp scissors make the job easier: It takes less effort to cut hair with sharp scissors, leading to less strain on the hairdresser's hands and wrists.
* Sharp scissors last longer: Properly sharpened scissors will stay in good condition for a longer period, saving the hairdresser money in the long run.
Hairdressers typically have their scissors sharpened professionally by a specialist, but some may use a sharpening tool themselves.
It's important to note that not all scissors need to be sharpened with the same frequency. The specific type of scissors (e.g., thinning shears, texturizing shears) and how often they are used will impact how often they need to be sharpened.
