Final answer:
In hairdressing, freeing up the cutting hand after combing a subsection into place is called palming, which allows for better control during the haircut.
Step-by-step explanation:
The act of freeing up the cutting hand after combing a subsection into place is known as palming. This technique is commonly used in hairdressing and barbering, where the stylist or barber holds the comb in the same hand as the shears but transfers the shears to a position where they are held against the palm, thus freeing the fingers to manipulate the comb and subsection of hair. This allows for better control and precision while cutting.
