A doobie wrap is a traditional Caribbean way of wrapping long hair around a person's head and pinning the damp hair with bobby pins to straighten it without using hot tools. This wrap is most useful in areas where high humidity might ruin hair that has been styled with heat.
The doobie wrap is used commonly in the Dominican Republic and Puerto Rico. Dominican salons in America also offer professional services for doobie-wrapping hair to give a woman a fashionable look without damaging her hair. The wrap also serves to protect hair during sleep, which is particularly useful for women with coarse hair that is difficult to tame.
