Hair shedding is a common problem associated with the application of human hair extensions. The shedding of hair usually starts at the attachment area, where the human hair extensions meet the natural hair line or the scalp. The reasons for this hair shedding could be friction at the point of contact, the quality of the glue or adhesive used to attach the human hair extensions or frequent disturbances to the hair due to their slippage. The three main causes of shedding of human hair extensions are low strength in natural hair which means they are unable to hold the human hair extensions, adverse reaction to the glue used for the human hair extensions and improper placement of the human hair extensions. While some hair shedding is predictable and natural, excess shedding resulting in the thinning of the natural hair indicates a serious under-lying problem which needs to the addressed. Sometimes, hair shedding may be unrelated to the human hair extensions and may be due to some other infection or deficiency, which needs professional treatment. In the initial days after installing, it is normal to shed some human hair extensions. For proper maintenance, human hair extensions require regular combing, shampooing, conditioning and moisturizing apart from regular visits to professionals. In case of excess shedding, you may need additional professional help apart from the once a month visit to the professional stylist.
