How to Wash a Human Hair Wig: Step-by-Step (Without Ruining It)

How to wash a human hair wig, in brief: detangle it dry from the ends up, rinse it in lukewarm water, then smooth a gentle sulphate-free shampoo through. Condition the lengths, avoiding the lace and knots, rinse in cool water, blot with a microfibre towel, apply a leave-in and let it air dry on a wig stand.

Key takeaways

• Detangle before the hair gets wet. Wet knots are much harder to undo and tend to snap.
• Work in one direction: water, shampoo and your hands all move from root to tip.
• Keep conditioner off the lace and the knots at the hairline.
• Never rub, wring or twist. Press, squeeze and blot.
• If the hair already feels dry, tangled or heavy with product, a professional treatment may be the better reset.

Why washing matters so much

Your own hair is fed by the oils your scalp produces. A wig is not. Every wash either protects the moisture it has left or strips it away, which is why technique matters more than brand of shampoo. Mpumie Madubedube, founder of The San Hair, put it bluntly in a 2024 interview with IOL: “One incorrect wash…can ruin your wig”.

What you need before you start

• A wide-tooth comb (and a soft paddle brush for straight hair)
• A gentle, sulphate-free moisturising shampoo
• A rinse-out conditioner and, ideally, a deep conditioner or hair mask
• A leave-in conditioner or light moisturising spray
• A microfibre towel or soft cotton T-shirt
• A wig stand or mannequin head
• Adhesive remover, if your wig was glued
• A basin or sink you can fill with clean, lukewarm water

How to wash a human hair wig, step by step

1. Remove any adhesive first. If the unit was glued, dissolve leftover glue along the lace with a proper remover and lift it away gently. Scrubbing set adhesive is how lace tears. Our HD lace guide explains why fine lace needs extra care.
2. Detangle dry. Start at the ends and work up to the roots in small sections. Curly units are the exception: finger-detangle only, or wait until conditioner is in.
3. Rinse in lukewarm water. Hold the wig by the cap, hair hanging down, and let water run from the cap towards the ends. Hot water tends to dry hair out; very cold water will not lift product build-up.
4. Shampoo with your palms, not your fingertips. Dilute a small amount of shampoo in water, then smooth it down the hair from top to bottom. Press it through; do not pile the hair on top and scrub.
5. Cleanse the cap gently. Turn the wig inside out and use your fingertips to clean the cap, where sweat and scalp oils collect.
6. Rinse until the water runs clear. Leftover shampoo leaves hair dull and stiff.
7. Condition the lengths. Apply conditioner from mid-lengths to ends and keep it away from the lace and the knots. Many stylists avoid conditioning the knots because it can loosen them over time and lead to shedding.
8. Deep condition when it needs it. If the hair feels dry, leave a mask on for the time on the label, or under a plastic cap.
9. Rinse in cool water and blot. Cool water leaves the hair smoother. Squeeze out water gently, then wrap and press the hair in a microfibre towel. Do not wring.
10. Leave-in, then air dry. Mist a leave-in through the lengths, place the wig on a stand and let it dry fully at room temperature before styling or storing.

Does the routine change for curly or coloured wigs?

How often should you wash a wig?

There is no single right number. A common rule of thumb among stylists is roughly every 7 to 10 wears for everyday wigs, sooner if you use a lot of product, live somewhere humid or train often. Washing too often wears hair out faster; washing too rarely lets product, sweat and oils build up at the cap and dull the hair. Watch for the signs: hair that feels coated, looks flat or smells less than fresh is ready. If you are in the gym or pool regularly, our guide on swimming, gym and sleeping in a wig covers the extra rinsing that sweat and chlorine call for.

Wig washing mistakes that cause the most damage

• Washing tangled hair. Water tightens knots. Always detangle first.
• Rubbing shampoo in circles. It roughs up the cuticle and causes matting.
• Using hot water and harsh shampoo. Both strip moisture a wig cannot replace.
• Wringing or twisting to dry. It stretches and breaks wet hair.
• Applying heat to wet hair. Let it dry, or use low heat with protection.
• Storing it damp. Trapped moisture in the cap can leave it musty.

When should you book a professional wig treatment?

Home washing keeps a healthy wig healthy. It does not always rescue one that has gone dry, tangled or heavy with build-up. That is where a salon treatment helps: our stylists deep-clean, treat and restyle the unit, and check the lace and knots while they are at it. Signs it is time: the hair still feels rough after conditioning, the nape keeps knotting, you notice more shedding than usual, or the lace has lifted or stretched.

Gentle hands, longer life

Washing a wig well is about patience more than products: detangle first, move in one direction, keep conditioner off the knots and let it dry on a stand. Do that and, with good care, a quality human hair unit often stays soft and full for much longer. For the bigger picture, read how to make your human hair wig last, or book a wig treatment on Fresha and let our stylists do the heavy lifting.

Frequently asked questions

What shampoo should I use on a human hair wig?

Choose a gentle, sulphate-free, moisturising shampoo. A wig does not receive natural oils from a scalp, so harsh cleansers strip moisture it cannot replace. For coloured units, such as blonde, burgundy or balayage, use a colour-safe formula. Diluting the shampoo in water helps it spread evenly without needing to scrub.

Can I wash my wig while it is installed?

If the wig is glued, it is usually better to have it washed in the salon or removed first, because water and product can loosen the lace adhesive and make cleaning the cap difficult. A glueless wig should always be taken off and washed on its own, then dried fully on a stand.

Should I put conditioner on the lace?

No. Apply conditioner from the mid-lengths to the ends and keep it away from the lace and the knots at the hairline. Conditioner on the knots can loosen them over time, which may lead to shedding. If the front needs moisture, use a very light leave-in on the hair only.

How do I dry a wig after washing?

Gently squeeze out excess water, wrap and press the hair in a microfibre towel without wringing, apply a leave-in, then let it air dry on a wig stand at room temperature. If you need to speed it up, use a blow-dryer on low with heat protection once the hair is mostly dry.

How often should I get a professional wig treatment?

It depends on how often you wear and style your wig. For a wig you wear most days, a monthly treatment is a simple rhythm that keeps the hair soft and the lace checked, and our Wig Maintenance bundle covers one for R349 a month. If your wig already feels dry or tangled, book a treatment sooner.
