As for lifetime Nazarites, it was common for them to braid the hair (like the seven braids on Samson—Judges 16:13) and to wind the braids around the head under a turban or other headgear. Samson was a warrior and he would never have allowed his braids to reach below his neck lest they be grasped by his enemies and cut off. Samson knew that cutting off his braided hair meant his strength was gone. This was the very part of his body that Samson would have wanted to secure as close to his head as possible. One thing for certain, lifetime Nazarites among the Israelites (and they were rare) did not let their hair hang down like the hair of women with which the “Jesus” we know since the fourth century has been depicted.
Jesus, however, was not under a Nazarite vow during his ministry because he also consumed wine and the fruit of the vine (Matthew 11:19) and this was prohibited to all Nazarites (Numbers 6:3). Though Jesus lived in the town of Nazareth, he was not a Nazarite. This shows that Jesus had short hair like all normal Jewish men at the time. Indeed, when Judas pointed out who Jesus was at the time of his betrayal to the priests, he kissed him on the cheek (Luke 22:48) rather than pointing out the man with the long hair. The simple truth is, Jesus while teaching on earth had short hair and all the early portraits of him made in the hundred or so years before the time of Constantine show him also as beardless.
I hope this will help you. It's the truth!
