Many were surprised by Grant\u2019s look since her hair is completely grey, although she is only 46 years old. Since many people like to dye their hair, some were puzzled by the fact that she wants to keep it gray. Grant offered an answer to this question via a post on a popular social media platform. The artist acknowledged that her hair grayed prematurely while she was in her 20s, and she dyed her hair for a while before realizing that her body cannot tolerate the chemicals which can be found in the dyes. One of the posts included an article about a recent study that explored the harmful effects of hair dyes.
