Description

Assembly of extension hair and attachment and detachment method using that}

The present invention relates to a joint assembly of the user's hair and the method of connecting and disconnecting the joint hair using the same in order to produce a variety of hairstyles, such as lengthening the user's hair length or thinning the hair, more specifically, After attaching both ends of the connecting ring to the top tip of the jointed hair to which a plurality of hairs are fixed with an adhesive, the auxiliary ring consisting of a hook and a handle is connected to the connecting ring which is tied together by a string so that the connecting ring is not separated. After inserting in the upward direction, and the joint hair assembly and the method of connecting and disconnecting the joint hair using the same type of tube or crimping ring is inserted into the ring of the auxiliary ring having a shrinkage.

Changes in the times require different styles of hair, regardless of gender, especially the use of joint hair techniques to lengthen or thicken hair, or simply apply or apply it to change color or shape. It is a common phenomenon to use a means to produce unique personalities, and the demand is exploding all over the world.
In the manufacture of such a joint hair, human hair or artificial hair is generally used. A hot air balloon melts an adhesive to make a tip on the top of the joint hair, and then the tip is placed on the user's hair and the hot air balloon melts the adhesive of the tip. Various techniques are used, such as connecting to a ring, inserting a ring into a user's hair and inserting a tip into the ring, pressing it with a forceps, attaching it to a tape type hair using adhesive tape, or applying an adhesive.
The pores used in these techniques are mainly used for heat gluer, knitting needle or hook, fryer, etc. Of course, problems such as damaging the scalp have been raised, and furthermore, there is a problem in that hair loss occurs and flows due to weakening of adhesive force due to physical property changes such as corrosion of the adhesive during use of the joint hair.
Even when the joint hair is terminated, it is necessary to use flammable chemicals to dissolve the adhesive or use a hot air balloon or a pore tool. Therefore, the above risks cannot be excluded, and the damage of the hair can not be avoided.

Therefore, in order to solve the above problems, the applicant of the present invention is a user's hair in a state in which a certain amount of joint hair is bonded to the inner surface such as a hair connection shrinkage tube or a connection ring as Utility Model Registration Nos. 316019 and 333865.

However, in the above case, the joint hair fused to the inner circumferential surface of the hair contraction tube or the ring is easily corroded due to the natural oxidation of the adhesive or the change of physical properties due to the use of various detergent oils such as shampoo. If partial hair loss occurs due to oxidation and corrosion, the hair loss progresses in series, causing the entire joint hair to become bald, and the inside of the joint is loosened, causing the hair connection contraction tube or ring to flow down, thereby failing to satisfy the function of the joint hair. The problem is pointed out.

Therefore, the present invention has been made to solve the inherent problems such as hair loss and runoff caused by using only the adhesive or the joint hair connection work by simple compression, and the risks caused by using flammable chemicals. In order to prevent the separation between the user hair and the joint hair by prolonged use or external pressure by increasing the bonding force when the user hair and the joint hair are connected, and the user hair by using a shrinking tube or a compression ring during the procedure Simplified operation and operation by connecting and disconnecting joint hairs safely and stably without any damage to the user's hair with easy operation that covers or crimps on the outer circumferential surface of the joint between the joint and the joint hair.
