Starting in 1968, Jesus was depicted with a beard in the WT publications. There is no real explanation as to why he had not been in the past (unless you see more in the pseudo archaeological comments I did not include). Note that it was possible to see bearded and nonbearded men in the early Christian congregation but not today. They cover their behind but putting in a paragraph saying beards on men are not appropriate now. But note the comment that beards may be required in Paradise.

When Jesus Christ was a man on earth, did he wear a beard?—K.A., U.S.A.
Biblical evidence is the most reliable testimony to be found on this question, and a recent careful review of what it says indicates that Jesus did indeed have a beard.
Jesus, born a Jew, “came to be under law” and he fulfilled the Law. (Gal. 4:4; Matt. 5:17) This was in order that he might pave the way for the abolishing of the Law and for release of the Jews from the curse of the Law, the condemnation of death that it brought against them. (Eph. 2:15; Gal. 3:13) Like all other Jews, Jesus was under obligation to keep the whole law. One of the commandments of the Law was: “You must not cut your side locks short around, and you must not destroy the extremity of your beard.” (Lev. 19:27) God doubtless gave Israel this law because among some pagans it was the practice to cut the beard in a certain fashion in worship of their gods. (Jer. 9:26; 25:23) Nevertheless, that law did not mean that a beard was not to be well kept, for in the Near East a well-groomed beard was considered a symbol of dignity and respectability.—2 Sam. 19:24….
Nevertheless, as already shown, it is apparent that Jesus did wear a beard, and so artistic representations of him in future Watch Tower publications will harmonize with the Scriptural evidence to that effect.
Doubtless the early Christians followed the custom of the time and locality in which they lived, with regard to the wearing of a beard. The Roman custom was beardlessness. Romans converted to Christianity would very likely continue in the Roman custom, while converts from the Jewish community would continue in the Jewish custom of wearing a beard.
Today Christian ministers, like the early Christians, are concerned with neatness and cleanness, but they strive to dress inconspicuously, so that their appearance does not in any way detract from the dignity or the effectiveness of the message they bear. (2 Cor. 6:3, 4) In recent years in many lands a beard or long hair on a man attracts immediate notice and may, in the minds of the majority, classify such a person undesirably with extremists or as rebels against society. God’s ministers want to avoid making any impression that would take attention away from their ministry or hinder anyone from listening to the truth. They know that people are watching true Christians very critically and that to a great extent they judge the entire congregation and the good news by the minister’s appearance as a representative of the congregation.
In paradise restored on earth it would not be out of order if men returned to wearing beards, in perfect fashion, like Adam in Eden.
