Boyd’s Bible Dictionary:
Worn short with elderly men, long with young men, vowed men and women
(Num. 6:5-95All the days of the vow of his separation there shall no razor come upon his head: until the days be fulfilled, in the which he separateth himself unto the Lord, he shall be holy, and shall let the locks of the hair of his head grow. 6All the days that he separateth himself unto the Lord he shall come at no dead body. 7He shall not make himself unclean for his father, or for his mother, for his brother, or for his sister, when they die: because the consecration of his God is upon his head. 8All the days of his separation he is holy unto the Lord. 9And if any man die very suddenly by him, and he hath defiled the head of his consecration; then he shall shave his head in the day of his cleansing, on the seventh day shall he shave it. (Numbers 6:5‑9); 2 Sam. 14:2626And when he polled his head, (for it was at every year's end that he polled it: because the hair was heavy on him, therefore he polled it:) he weighed the hair of his head at two hundred shekels after the king's weight. (2 Samuel 14:26); Luke 7:3838And stood at his feet behind him weeping, and began to wash his feet with tears, and did wipe them with the hairs of her head, and kissed his feet, and anointed them with the ointment. (Luke 7:38)). Lepers shorn (Lev. 14:8-98And he that is to be cleansed shall wash his clothes, and shave off all his hair, and wash himself in water, that he may be clean: and after that he shall come into the camp, and shall tarry abroad out of his tent seven days. 9But it shall be on the seventh day, that he shall shave all his hair off his head and his beard and his eyebrows, even all his hair he shall shave off: and he shall wash his clothes, also he shall wash his flesh in water, and he shall be clean. (Leviticus 14:8‑9)).
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. 19:2727Ye shall not round the corners of your heads, neither shalt thou mar the corners of thy beard. (Leviticus 19:27)). Neither were they to make any baldness between their eyes for the dead (Deut. 14:11Ye are the children of the Lord your God: ye shall not cut yourselves, nor make any baldness between your eyes for the dead. (Deuteronomy 14:1)). Baldness should come as a judgment (Isa. 15:22He is gone up to Bajith, and to Dibon, the high places, to weep: Moab shall howl over Nebo, and over Medeba: on all their heads shall be baldness, and every beard cut off. (Isaiah 15:2); Jer. 9:2626Egypt, and Judah, and Edom, and the children of Ammon, and Moab, and all that are in the utmost corners, that dwell in the wilderness: for all these nations are uncircumcised, and all the house of Israel are uncircumcised in the heart. (Jeremiah 9:26), margin; Jer. 48:3737For every head shall be bald, and every beard clipped: upon all the hands shall be cuttings, and upon the loins sackcloth. (Jeremiah 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. 11:6-156For if the woman be not covered, let her also be shorn: but if it be a shame for a woman to be shorn or shaven, let her be covered. 7For a man indeed ought not to cover his head, forasmuch as he is the image and glory of God: but the woman is the glory of the man. 8For the man is not of the woman; but the woman of the man. 9Neither was the man created for the woman; but the woman for the man. 10For this cause ought the woman to have power on her head because of the angels. 11Nevertheless neither is the man without the woman, neither the woman without the man, in the Lord. 12For as the woman is of the man, even so is the man also by the woman; but all things of God. 13Judge in yourselves: is it comely that a woman pray unto God uncovered? 14Doth not even nature itself teach you, that, if a man have long hair, it is a shame unto him? 15But if a woman have long hair, it is a glory to her: for her hair is given her for a covering. (1 Corinthians 11:6‑15)). “Hair as the hair of women” is a symbol of subjection to a head, and effeminacy (Rev. 9:88And they had hair as the hair of women, and their teeth were as the teeth of lions. (Revelation 9:8)).
