Frequently Asked Questions
Can I use oil treatments on synthetic wigs and extensions?
Lightweight oil treatments can help control frizz on some synthetic fibers, but they won’t penetrate synthetic strands the way they do human hair. Test a small, hidden section first to ensure the oil doesn’t change the synthetic texture or shine.
Will a medicated leave-in spray stain wig caps or fabrics?
Most non-greasy leave-in sprays are formulated to absorb without leaving heavy residue, but anything with active ingredients or menthol can leave traces. Apply sparingly and allow to dry fully before putting on a wig cap; blot excess on a towel if concerned.
How often should I use a full kit versus a finishing oil?
Use a full shampoo/conditioner kit on a regular wash schedule appropriate to your hair and wig routine (weekly to biweekly). A finishing oil can be used sparingly after styling—typically a drop or two on mid-lengths to ends—to add shine between washes without overloading the piece.
