  • Patent number: 5156172
    Abstract: A fastener of a hair-treating device is first slid into position adjacent a human scalp and, thereupon, is affirmatively locked on a bundle of hair in a non-slip manner. A shield attached to the fastener is opened to receive a different bundle of hair for application of a treating agent, and thereupon closed to prevent the treating agent from seeping to the balance of hair on the scalp. An independently operated bleed-guard further resists treating agent seepage.
