Abstract: Foreign hair is attached to naturally grown scalp hair. First, a strand of scalp hair is combined with a strand of foreign hair. A clamping sleeve is slipped onto the loop of a loop catcher. Then the combined strand is inserted into loop and it is pulled into and through the clamping sleeve with the loop catcher. The combined strand of scalp hair and foreign hair are then preliminarily attached by pre-squeezing the sleeve. After the sleeve is properly placed in the vicinity of the scalp, the sleeve is finally pressed so as to clamp the foreign hair to the scalp hair. The sleeve, which is preferably of the same color as the hair, may be removed by prying it open with bent-nose pliers provided with the invention.
