What is white eye brow?

White eyebrow refers to a condition where the eyebrows have turned completely white or gray due to a lack of pigmentation. This condition can occur naturally with aging or can be caused by certain medical conditions such as vitiligo or alopecia areata. White eyebrows can also be a side effect of chemotherapy treatment. In some cases, the whitening of eyebrows may also be accompanied by whitening of hair on other parts of the body such as the scalp, eyelashes, and beard. It is important to note that white eyebrows do not typically cause any medical issues, but some people may choose to dye their eyebrows to match their hair color for cosmetic reasons.
