Why do women change their natural appearance? Probably the same reason why men shave their God-given beards ( that distinguishes their faces from women's faces), wear useless ties (sometimes with tie clasps), use deodorant, mouthwash and men's cologne (changes their natural odor), color their graying hair, wear toupees ( or just grow out their thinning hair and then comb it sideways to cover their balding head), work out at the gym to build muscles that they really don't need, wear short hair (Jesus' hair is down to His shoulders), wear pants (a style derived from pagan barbarians), etc.
Getting back to women, a "natural" woman would never shave her legs or under her arms, wear deodorant, perfume, or use mouthwash, curl her straight hair or straighten her frizzy hair, color her gray hair, use lotions to soften her dry skin, powder her oily, shiny face, etc.
Of course, some Adventists think it's o.k. to color, curl, mousse, perm, straighten, whatever, the hair on top of the head, but don't dare color or curl the hair on the eyelids (eyelashes). And the difference is?
