The latest information that I remember is from the Sept 2016 Study article "Does your Style of Dress Glorify God?"
17 What about the propriety of brothers
wearing a beard? The Mosaic Law required men to wear a beard. However,
Christians are not under the Mosaic Law, nor are they obliged to observe
it. (Lev. 19:27; 21:5; Gal. 3:24, 25)
In some cultures, a neatly trimmed beard may be acceptable and
respectable, and it may not detract at all from the Kingdom message. In
fact, some appointed brothers have beards. Even so, some brothers might
decide not to wear a beard. (1 Cor. 8:9, 13; 10:32)
In other cultures or localities, beards are not the custom and are not
considered acceptable for Christian ministers. In fact, having one may
hinder a brother from bringing glory to God by his dress and grooming
and his being irreprehensible.—Rom. 15:1-3; 1 Tim. 3:2, 7.
