Things You Should Not Do
Use oil sheen and/or heavy oils (they weigh the hair down)
Blow dry (always allow your hair to air dry)
Use sulfate shampoos (see recommended shampoos)
Sew through the welfts (it can cause the hair to shed (professional installations highly recommended)
Try at-home coloring techniques (seek a professional)
Don't scrub hair as you would your hair, wash flat while using a wig brush or wide tooth comb
