makeup, hair improvement kit process. The present invention relates to a composition comprising a compound of formula (I) wherein the dotted bonds represent a single or double bond； r and r <；39>； are individually selected from the group consisting of hydrogen, a straight or branched C1 -C6 alkyl chain which may be substituted； x is selected from the group consisting of a halide, a halide containing group or a hydrogen； y is 0 or 1, x is 0 or 1, and x and y are not both 1 or not both 0； or your salt. Topical compositions and methods of topically applying a hair-modifying composition are also described wherein the modification includes enhancing a lock of hair in a subject or hair that is not biologically linked to or is not naturally a part of a subject (e.g. , hair from a wig or extension) (unnatural hair). In another embodiment, the modification includes increasing hair curl together with hair conditioning and / or cosmetic enhancement of hair appearance or beauty (eg, increased look and softness and silky sensation). thus, the described compositions may be applied to existing hair over the scalp or eyelids or unnatural hair to enhance the curl and / or the look and feel of the hair. in one embodiment, a composition includes an effective amount of a compound (molecule) represented by the following formula (ii) wherein the dotted bonds represent a single or double bond and when a bond in any chain is a double bond, cis or trans configuration. is contemplated； wherein a and b are individually selected from a hydrogen atom, a hydroxyl group (-oh), and a halogen atom (for example, a fluorine atom), provided that when one of a and b is a hydroxyl group, the other of a and b is a hydrogen atom and when one of a and b is a halogen atom, the other a and b is a halogen atom or a hydrogen atom； where z is a cycloalkyl moiety having from three to seven carbon atoms, an aryl moiety including from four to ten carbon atoms or a heteroaryl moiety including from three to nine
