Ever go to a salon and hear a colorist talk about "virgin hair"? Don't worry — she's not snooping into her clients' love lives. Virgin hair is simply hair that hasn't been chemically altered with dye, relaxer, perms, or other treatments.
Virgin hair is no better or worse than chemically treated hair, but it tends to be stronger and softer than its processed version. Another perk: If a virgin-haired person decides to dye her hair, the color will usually be more even than it would be on someone with previously dyed hair. At that point, the hair's "deflowering" is finished . . . until more virgin hair grows in.
