Seamless hair extension method

Abstract

A seamless hair extension method, more particularly a seamless fast hair extension method for fast performing hair extension in a painless manner, includes a native hair processing step, a to-be-extended hair processing step, an adhesive bonding step, a bundle bonding step and a trimming step, so that the hair extension step and time can be shortened, and a hair extension effect is firm. Moreover, because they are radially serially connected into one piece, every bundle of hair is arbitrarily movable at a hair root, and no discomfort pain is caused by the long time of usage. Meanwhile, the scalp disease cannot be caused, and the personal scalp health can be promoted.

What is claimed is: 
     
         1 . A seamless hair extension method for serially connecting a to-be-extended hair to a bottom end of a native hair, the method comprising:
 a native hair processing step of determining hair quality information of the native hair, defining the native hair of a to-be-hair-extended person as an upper region close to a top of a head and a lower region close to a neck, putting up and positioning the upper region at the top of the head, and grouping multiple hair lines of the native hair of the lower region into series of native hair bundles;   a to-be-extended hair processing step of selecting the to-be-extended hair with approximate patterns according to the hair quality information of the native hair and a to-be-serially-connected length, and dividing the to-be-extended hair into series of to-be-extended hair bundles corresponding to a number of the native hair bundles;   an adhesive bonding step of covering a rubber sleeve made of a transparent plastic material onto each of the to-be-extended hair bundles of the to-be-extended hair, making ends of the corresponding native hair bundles and ends of the to-be-extended hair bundles be radially mutually overlapped with and insertion-connected together, and then adding a quick drying adhesive for rubbing and adhering into an overlapped and insertion-connected region, so that a serial connection segment is firstly pre-formed between the native hair bundle and the to-be-extended hair bundle, and hot pressing is performed after drying, and the adhesive bonding step of bonding each of the native hair bundles and each of the to-be-extended hair bundles is completed one by one;   a bundle bonding step of covering the rubber sleeve on each of the to-be-extended hair bundles of the to-be-extended hair with an outside of the serial connection segment, and then clamping the rubber sleeve of each of the serial connection segments at a clamping temperature higher than a hot-pressing temperature of the hot pressing of the adhesive bonding step, so that the bundle bonding step of each of the native hair bundles and each of the to-be-extended hair bundles can be completed; and   a trimming step of putting down the upper region of the native hair to cover the serial connection segment between each of the native hair bundles and each of the to-be-extended hair bundles, and finally performing perming and dying according to requirements to trim a corresponding hair extension style.   
     
     
         2 . The seamless hair extension method according to  claim 1 , wherein an instrument analyzes and determines the hair quality information in the native hair processing step. 
     
     
         3 . The seamless hair extension method according to  claim 1 , wherein the hair quality information comprises oiliness, thickness and hair color. 
     
     
         4 . The seamless hair extension method according to  claim 1 , wherein in the native hair processing step and the to-be-extended hair processing step, numbers of the native hair bundles and the to-be-extended hair bundles substantially range from 50 to 115. 
     
     
         5 . The seamless hair extension method according to  claim 1 , wherein each of the native hair bundle and the to-be-extended hair bundle comprises the hair lines having a number substantially ranging from 180 to 280. 
     
     
         6 . The seamless hair extension method according to  claim 1 , wherein the temperature of the hot pressing in the adhesive bonding step ranges from 80° C. to 110° C. 
     
     
         7 . The seamless hair extension method according to  claim 1 , wherein the clamping temperature in the bundle bonding step ranges from 90° C. to 120° C.
