Repairing a wig starts with diagnosis. A tangled wig, a frizzy wig, a torn lace front, and a stretched cap are different problems. Do not treat them all with conditioner.
If the wig is tangled
Mist, section, and detangle from the ends. Do not wash first if the knots are severe; water can tighten mats.
If the fiber is frizzy
For synthetic hair, steam or low heat can smooth fibers if the wig is heat-safe. Trim destroyed ends rather than fighting every strand.
If the cap is damaged
Loose wefts can be stitched back. Small lace tears may be patched. A stretched cap may need elastic replacement or a wig grip to keep wearing it.
When to retire it
If the lace is shredded, the hairline is bald, or the synthetic fiber feels rough immediately after repair, the wig may not be worth more time.
Bottom line
Repair the specific failure: tangles, frizz, lace, cap, or shedding. The right fix depends on what actually broke.
