Is it wrong for a male to wear long hair, braids, or dreadlocks?
The answer to a previous question, “What does God say about men wearing earrings?” applies directly to your question. You may want to read it before you proceed.
In the Old Testament period the priests wore underwear under their long outer garments which were like robes. This can be observed by comparing Exodus 20:26 with Exodus 28:42-43.
Make linen undergarments as a covering for the body, reaching from the waist to the thigh. Aaron and his sons must wear them whenever they enter the Tent of Meeting or approach the altar to minister in the Holy Place, so that they will not incur guilt and die. (NASB) Exodus 28:42-43
And do not go up to my altar on steps, lest your nakedness be exposed on it. (NASB) Exodus 20:26
This pattern of dress suggests that men normally wore long outer garments and they did not wear underwear.
In an answer to a previous question we found that scripture prohibits men from looking like women and women from looking like men. This principle is applied to any practice that blurs the appearance of the sexes. For example, scripture says men can have long hair so long as it is not as long as women’s hair. Today most women wear their hair just above the shoulder. If we apply both principles together, they would indicate that men should keep their hair shorter than “just above the shoulder.” As culture changes, men and women need to avoid looking like the opposite sex. That is God’s principle! The priests were commanded to not shave their hair nor to grow their hair too long.
They must not shave their heads or let their hair grow long, but they are to keep the hair of their heads trimmed. (NASB) Ezekiel 44:20
We are not sure what is meant by “grow long.” From 1 Corinthians 11:14-15, it appears that women had the longer hair.
Scripture indicates that men did wear rings (James 2:2) and it says that women wore jewelry (1 Tim. 2:9). Scripture never refers to men wearing other jewelry.
The principle in scripture is that men and women should avoid looking like one another. What a man and woman can wear will change as the culture changes.
