How to Wash a Weave or Wig Without It Getting Greasy or Matted

Most matted, greasy installs aren't bad hair — they're bad washing. Bundles and units don't get natural scalp oils, so they need to be treated differently from your own hair. Here's how to keep them soft.

Detangle dry, from the ends up

Before any water touches it, gently finger-detangle and then comb with a wide-tooth comb starting at the tips and working up to the root. Wetting a tangled install just locks the knots in tighter.

Wash downward, never pile it up

Run lukewarm water down the hair in the direction it falls. Apply a sulfate-free shampoo (or co-wash) by smoothing it down the shaft — do not scrub, swirl, or pile the hair on top of your head. Swirling is exactly how you mat a weave. For a sew-in, focus the shampoo on your scalp and the tracks, then let the suds rinse down the length.

Condition the lengths, not the roots

Greasy installs usually come from over-conditioning. Keep conditioner and leave-in on the mid-lengths and ends, and keep it off the wefts/roots and (for a unit) off the lace. Rinse until the water runs completely clear — leftover conditioner is what goes stiff and greasy by day two.

Air-dry and store it right

  • Air-dry on a stand (units) or let a sew-in dry fully before styling — going to bed on a damp install breeds mildew smell.
  • Once a month, clarify with a small amount of diluted clarifying shampoo to strip product buildup that makes hair feel coated.
  • Store units on a wig head, not crumpled in the box. Wrap a sew-in at night.
A note on your scalp and edges: Persistent scalp itching, soreness, flaking, or hair thinning under an install is worth a dermatologist or trichologist — not just more product. Inches is a buying guide, not medical advice.
