Boyd’s Bible Dictionary:

Concise Bible Dictionary:
Given by God as an ornament and a protection for the head. The Israelites were not to “round the corners of their heads,” doubtless in allusion to some heathen practice, one of which has been described as “cutting the hair in a ring away from the temples” (Lev. 19:27). Neither were they to make any baldness between their eyes for the dead (Deut. 14:1). Baldness should come as a judgment (Isa. 15:2; Jer. 9:26, margin; Jer. 48:37).
Long hair is referred to in the New Testament as the natural covering, of a woman, as owning her subjection to the man, and is a glory to her; but nature teaches that if a man have long hair, it is a shame to him His head must not thus be covered, for “he is the image and glory of God” (1 Cor. 11:6-15). “Hair as the hair of women” is a symbol of subjection to a head, and effeminacy (Rev. 9:8).
