Beard grooming is not as expensive as often perceived. You can achieve a good look with some pocket friendly products as well, as long as you have the grooming skills and tools.
A good quality beard shampoo, as opposed to a soap, will nourish your beard hair. Soap often leads to dryness and hair fall as it is harsh on your skin. Beard shampoo works best when used with a nice conditioner. This is a bit extravagant but totally worth it. You do not need to shampoo daily. Once in two or three days will do if you do not have very oily skin. On days you don’t use a shampoo, you can always just rinse it well for hygiene. You can use towel or tissue to dry it out.
