Can you tell me if i trim my facial hair, will it grow back thicker?

Myth: No — shaving hair doesn't change its thickness, color or rate of growth. Shaving facial or body hair gives the hair a blunt tip. The tip might feel coarse or "stubbly" at first but will thin out as it grows. During this phase, the hair might be more noticeable and perhaps appear darker or thicker — but it's not. Another option to shaving is laser hair removal if you want to remove the hair.
