Clamp devices for use in selectively altering hair color-color, especially advantageous for use with off-the-scalp type bleach materials, comprising two bars hinged at one end to each other with a latch at the other end for removably holding them in the closed position with one face of one bar tightly against the opposed face of the other bar. The adjacent faces of each are aligned so that they may be placed close to the scalp with tresses of hair between the opposed faces, one of which may have spaced recesses for the tresses. A shield, e.g., a sheet of plastic, preferably is secured along one edge to one of the bars which extends away from said aligned edges far enough to underlie the tresses held in the clamp and protect the underlying bar from hair color altering liquids applied to the clamped tresses. For maintenance treatments where hair color altering materials should be applied to new growth only, a second clamp may be provided to be applied to the clamped tresses at the end of the new growth and it may have any desired structure, e.g., a hollow bar with an elastic band secured at one end to one end of the hollow bar and the other end removably securable to the other end of the hollow bar.
A device for use in selectively altering hair color comprising a pair of bars hinged together at one end having opposed hair engaging surfaces to receive a strand of hair between them, said bars having aligned bottom surfaces permitting the bars to be placed around a strand of hair close to the scalp, means for removably holding the bars with said surfaces in gripping relation to a strand of hair between them, and a hair protecting shield connected to a bar and extendingly only transversely away from the gripping surface adapted to be positioned between a strand gripped by said bars and surrounding hair underlying said shield whereby said strand of hair may be formed by combing and be held in one hand of a person while the clamp in open position is moved transversely across the strand and then closed upon it.
A hair treatment device comprising a clamp having an elongated holding bar and an elongated clamping bar hinged together at one end, said holding bar including a strand of hair and said clamping bar including a strand engaging surface adapted to be removably pressed against the said strand engaging surface of said holding bar to hold the clamp to a strand of hair when it is placed between said bars, the strand engaging surfaces of said bars terminating at aligned bottom surfaces of said bars whereby a clamp is adapted to grip a strand at the scalp, and a resilient latch on the other end of one of said bars extending onto the other end of the other bar, and means including a latching projection and a recess to receive the projection for removably holding said bars in gripping position on a strand of hair.
