When May One Be Lenient Regarding Dyeing the Hair of the Beard

Are there cases in which one may be lenient and dye the hair of the beard?

Shalom u’vrachah 

In general, it is forbidden for a man to dye his hair because of the prohibition of “לֹא יִלְבַּשׁ” (“A man shall not wear [a woman’s garment]”), since this is part of the beauty practices of women. 

In a situation of embarrassment, such as when one’s appearance is truly unusual and causes shame, the poskim permitted dyeing the hair. 

Some poskim also permitted it for the sake of livelihood—when he would not be hired because he looks older than his age—or for the purpose of a shidduch.
