A full lace cap is a delicate structure made by tying strands of hair to a fine mesh, so it needs to be treated with extra care. As such, a full lace wig should not be worn daily because the mesh will fray, and the hair will shed prematurely due to the constant pressure and stress on the strands.
Some of the main reasons that can affect longevity are:

• Hair Quality: Hair that is virgin, with cuticles remaining sealed, tends to last much longer than hair that has been heavily processed or chemically treated.
• Adhesive: Rubbing alcohol and attempting to tear the lace off while you're trying to remove it can ruin your caps.
• Styling: Too much heat, overstyling the wefts and over-bleaching the knot itself will ruin your attachments.
• Maintenance: Deep conditioning and keeping your unit on a mannequin head overnight will help keep your closure for a longer duration. You'll want to try to alternate between 2 closures and use sulfate-free cleansers. Alternate between 2 units and use gentle, sulfate-free cleansers.
