ABSTRACT OF THE DISCLOSURE The present specification discloses a hair spray composition which retains the good curl holding ability of compositions known from the prior art as well as the absence of harshness and brittleness to the feel, but which will not develop perceptible or objectionable discoloration upon standing even at elevated ambient temperatures to which such hair spray could become exposed, by incorporating in the composition an amount of an alkali metal borohydride or of an oxidizer, effective to prevent such discoloration. In practice it was found that with the usual concentrations of the neutralizing base and the degree of neutralization, from about 0.01% to about 0.05% of the alkali metal borohydride or from about 0.4% to about 1.5% of the oxidizer, expressed as H2O2, will be effective to accomplish the desired objective.
