Using K18 on extensions alone or on clients with previously installed extensions:
K18 is suitable for use on all human hair extensions (to include tape-in, k-tip, hand tied, clip-in, sew-in, etc.). For information on using K18 on clients with previously installed extensions, please follow the instructions for the specific service being performed.
PRO tip: When working on clients with tape-in extensions, we recommend following the standard protocol for cream-based conditioner or oil usage. For best results, do not apply the K18 professional molecular repair hair mask or molecular repair hair oil directly to the weft adhesive or to the natural hair immediately surrounding the adhesive as it could cause slippage.
