If you live in a normal climatic area, where the air does not lack humidity, it is advisable to apply it once every day. However, for people living in places that are dry and arid, the hair becomes prone to dryness and requires regular moisturizers. This is when you have to apply it twice a day. Apply it after shower on a slightly moist beard. Also, the people using it twice should apply it the second time before going to bed.
