We are currently using a range of needles varying from 20 gauge to 24 gauge. Often the choice of the gauge depends on the girth of the FU to be placed. We value safety above all. It is no point trying to place a graft thicker in diameter than the diameter of, say, a 24-gauge needle into a 25 gauge needle hole. Remember, not only do we have to create minimal trauma in the recipient area by the needle, we also have to ensure minimal trauma to the FU during placement. Keeping both these variables in mind we have used needles as per the requirement of each patients hair. Single hair follicle (medium thickness) – 24 gauge needle...... Single hair follicle (curly & above average thickness) – 23 gauge needle...... 2 hair FU – 21 to 22 gauge depending on hair thickness...... 3-4 hair FU – 18 to 20 gauge needle.
