Dax's Marvelous Moustache

 You touch a willing creature, who immediately grows facial hair the color and style of your choice, even if it is not normally capable of growing it. This hair does not grow as normal hair would unless the affected creature is already capable of growing it. This facial hair lasts until it is shaved off, or you cast this spell again to alter the color or style.

At higher levels.

When you cast this spell at 4th level or higher, you permanently alter the affected creature's physiology to become capable of naturally growing facial hair of the style and color you create. This effect may only be undone by a Wish spell.
