The hair should be damp. You straigten it and get it parallel with a comb and cut it to equal length along the comb. Gage the length for successive cuts against the hair you already cut (about half of the strand should have the new length). When you Do not snip off too much in one go. You can always cut off more.
BTW:
Telly Savalas is perhaps best known for his role as Lt. Theo Kojak. His hair would not exactly be considered as long wink.
