Beard is purely genetic make up. It could be a pituitary issue, hair follicle or their lack of, or could possible even be genetics. To make hair grow you need to stimulate, moisturize, and cleanse. Use a soft bristle scrub brush for the face and use circular motions using a eucalyptus, menthol, and/or peppermint type cleanser or lotion. The invigoration of the brush and cleanser/moisturizer will wake up that hair follicles and gives them a signal to produce.
