Summarize:

Your genetic profile is the primary factor in how quickly (and how fully) your beard grows, and there's not much you can do about that. While you can take measures to support the process and increase the growth, you should also accept that your beard will grow in its own way and at its own pace. Some people say that regularly trimming your beard will stimulate faster growth, but there's no evidence to support this. It's possible that frequent shaving before you start growing a beard may stimulate the hair follicles to grow faster, but the evidence for this is also limited at best. So, once you start growing a beard, just let it grow! Wet your face with warm water. If you haven't started your beard yet, massage in a gentle face cleanser. If you do have a beard coming in, also use a mild shampoo on just the facial hair. Rinse the cleanser and/or shampoo away with cool, clean water, then pat your face dry with a soft towel. Do this every morning and evening. Washing your face regularly will help to remove dirt and oil from your hair follicles. This makes it easier for them to grow. To test if a cleanser is gentle enough for your skin, apply a small amount to your chin and leave it for 10 minutes. If you don't have any signs of a reaction (like redness or irritation), you can try washing your face with the cleanser. Apply firm but not painful pressure on your face with your fingertips, then massage in small circles over your beard-growing area. Do the massage for about 10 minutes, twice per day. once per week. Wash your face as normal with your gentle cleanser or shampoo, but rinse with warm water and leave your skin damp. Gently massage in the exfoliant over your entire face (including any facial hair), then rinse it away completely with clean water and pat your face dry. Exfoliating will help to clear away dead skin cells that may be impeding your hair follicles from achieving their full growth potential. Before using an exfoliant on your entire face, test a small patch on your chin for 5-10 minutes. If you don't feel any burning or irritation, you should be good to go. While you should be wary of any product claims made for stimulating beard growth, beard oils and beard softeners may, in fact, provide some benefits. Keeping your beard hairs soft and hydrated may encourage slightly faster growth. Avoid beard oil if you have acne, though. It may worsen your breakouts. At the very least, using beard products will make your beard look and feel better, no matter how fast it's growing. As with most home remedies, the supporting evidence for beard stimulators is limited at best. They aren't likely to cause any harm, though, so consider trying one or both of the following: Create a thin paste out of 1UStbsp (15ml) of fresh-squeezed lime juice and 1 US tbsp (15 g) of ground cinnamon. Apply it to your beard in a thin layer, leave it for 20-30 minutes, then rinse it away and use your normal face cleanser. Use this paste 1-2 times per day, but stop if you notice any irritation. Blend 3 US tbsp (45 g) of dried mustard leaves with 2floz (59ml) of amla oil until it forms a smooth paste. Apply it in a thin layer over your beard, leave it for 15-20 minutes, then rinse it away and wash your face with your normal cleanser. Refrigerate any remaining paste and use it daily for 2-3 days.
Be patient and let your facial hair grow. Wash your face twice per day to unblock hair follicles. Massage your face twice daily to stimulate the follicles. Exfoliate your face Pamper your growing beard with beard oil or softener. Try homemade beard-stimulating recipes.
