There is a passage in Scripture that clearly shows that God regards long hair on a male as something shameful and disgraceful:

“Does not nature itself teach you that for a man to wear long hair is degrading to him, but if a woman has long hair, it is her pride? For her hair is given to her for a covering” (1 Cor. 11:14,15).

The contrasts between the hair lengths of males and females is part of the divinely intended distinction God has placed between the sexes. Males wearing very long hair, in effect, are appearing womanish, or effeminate. They are blurring God’s guidelines. This conclusion ought not to be dismissed lightly. Persons guilty of womanish conduct — effeminacy — were regarded as an abomination in Israel (Deut. 22:5). In the New Testament effeminacy is regarded as a sin so serious as to be placed alongside fornication and homosexuality (1 Cor. 6:9).
