According to the Padma Purana the name refers to Krishna's long, beautiful looking unshorn hair.
In the Bhagavad Gita Arjuna uses the name Keshava for Krishna a number of times, referring to him as the 'Killer of the Keshi demon' : I am now unable to stand here any longer. I am forgetting myself, and my mind is reeling. I see only causes of misfortune, O Kesava, killer of the Keśī demon. (Bhagavad Gita 1.30). The demon Keshi, in the form of a horse, was sent by Kamsa to kill Krishna but was overpowered and slain (Vishnu Purana 5.15-16).
