With a skilled surgeon and careful following of post-op guidelines, (and without unfavourable skin characteristics or very low density in the donor region) cutting to a 3 guard should be possible in most cases. Some patients can go down to a 2.
And this is a fellow who followed all the instructions but due to thin surrounding hair and some shockloss his scar was VERY visible at 3 months (first pic) but turned out great at 6 months.
