Definitions

• the present invention relates to a hair composition in which a substance to be oxidized, an enzyme which utilizes oxygen as a substrate and does not produce hydrogen peroxide, and a cyclodextrin compound are compounded and, more particularly, it relates to a hair composition having a good stability with a lapse of time and being suitably able to be used as a reactive hairdye (a single preparation type) , a permanent-waving preparation of a single preparation type , a depilatory of a single preparation type, etc.
• the present inventors have carried out an intensive study for achieving the above-mentioned object and, as a result, have found that , when a cyclodextrin compound is compounded with a hair composition wherein a substance to be oxidized and an oxidase which is an enzyme generating no hydrogen peroxide and utilizes oxygen as substrates are compounded, the said substance to be oxidized and the said oxidase are included in the said cyclodextrin compound whereby generation of insoluble aggregates, etc. as the time goes by is suppressed as shown in the examples mentioned later and stability with a lapse of time of the said hair composition is significantly improved.
• the present invention has been accomplished consequently.
