A method for treating and/or styling selective sections of hair on a person's head is disclosed. The method includes the use of a substantially transparent polymer film having a thickness of approximately 0.025 mm. The hair is weaved in order to isolate the sections of hair to be treated. The film is placed against the hair to be treated and a chemical is applied to the hair. Typically, rolling or folding the film onto itself accomplishes sealing or bonding of the film. Optionally, a second film is placed over the first film with the treated hair contained between the two films. Static conductivity facilitates sealing of the film or films. The film or films as a result of the sealing or bonding contain the section of hair and chemical. Chemical development, accelerated by the static conductivity, is observed through the substantially transparent film. Hair, isolated during the treatment process, can be cut with the film and chemical in place, by cutting right through the thin film and hair at the same time. When the desired hair treatment results are achieved, the film or films and chemical are removed from the hair.
