Hi, That`s a poly[` skin` ] base.....unlike lace, you have to begin the removal process by spraying lace-release [alcohol] at the perimeter [usually start at the front hairline] ...allow it a minute to begin breaking down the glue /tape underneath....gently peel back that front bit until you feel ` resistance` ..spray on more lace release, wait for it to ` work` and gently peel the system back further, and so on........once removed, you then need to use a different percentage of alcohol to loosen / remove residue both from the scalp and / or base ......``Pure`` is one which is widely used ..it`s available from John, along with lace-release. For really stubborn residues, you should use a citrus-based Solvent such as C-22, De-solv-it or ReMove .....
