Hi, Glue extensions, or double sided tape, are often used with popular lace wigs. Unfortunately, they can cause damage that is often permanent. The glue can block your scalp pores and damage your hair follicles as well as burn and dry out your hair. Heavy extensions pull on your scalp resulting in thinning hair. It is difficult to clean your scalp with glue extensions in it creating unhealthy hair. Sometimes hair extensions can cause headaches and bald spots. Hair bonding glue contains high concentrations of soluble latex antigen and may cause anaphylaxis without mucosal contact. Repeated glue exposure may potentially sensitize consumers. Physicians, cosmetologists, and latex-allergic patients should be aware of bonding glue-induced immunoglobulin E-mediated reactions associated with hair alterations. Probably because the products made from latex are increasing in number, reactions to latex have become more common. Latex is found in balloons, rubber bands, condoms, elastic bands, bathing suits, underwear, waistbands, and rubber toys. The reactions to these items go beyond contact dermatitis, and may cause asthma, or even anaphylactic shock. Hope I have answered your query. Let me know if I can assist you further.
