Some shedding is normal and some is a fault, and the difference is not how much hair you see — it is where it is coming from. Work that out first, because the fixes are completely different.
What normal looks like
A new unit sheds for the first two or three wears. Those are loose strands left in the cap from manufacture, and they stop. After that, five to ten strands a day on a unit you brush and style is unremarkable.
What is not normal: a visible thinning at the parting within weeks, bald patches in the lace, or a handful of hair every time you touch it. That is a construction or a handling problem.
Where the hair is leaving from
Pick up a shed strand and look at the end that was attached.
- A small knot at the tip — the strand came out of the lace, knot and all. The knots are failing.
- A clean cut end — it came loose from a weft. The weft is unsealed or has been cut.
- A broken, frayed end — this is not shedding at all, it is breakage. The hair snapped mid-shaft.
Each points somewhere different.
Cause one: the knots are not sealed
Every strand in a lace area is hand-tied in a knot. Those knots should be sealed, and on a well-made unit they are. Unsealed knots loosen with movement, and once one goes its neighbours follow, which is why lace shedding spreads outward from a patch rather than appearing evenly.
Bleached knots are more fragile than unbleached ones — bleach lightens the dark dot so it disappears against the scalp, but it weakens the knot doing it. That trade-off is covered in the bleached knots guide. A unit with heavily bleached knots and no sealant will shed, and there is not much to be done about it after the fact.
Cause two: a cut or unsealed weft
If the shedding is from the wefted area rather than the lace, the usual cause is a weft that has been cut — by you, to adjust the cap, or at the factory. A cut weft unravels from the cut end outward and will keep going until it is sealed.
Never cut a weft without sealing it. If one has already been cut, a bead of weft sealant or clear fabric glue along the cut edge stops the unravelling.
Cause three: you, probably
Most shedding is handling, and the biggest single culprit is combing dry hair from the root down. Every stroke that starts at the cap drags accumulated knots through the lace and pulls strands out of it. Working from the ends upward, on damp hair, holding above the knot, eliminates most of it — the detangling guide sets out the full order.
The others:
- Over-washing. Every wash moves every knot. Eight to ten wears between washes, not weekly.
- Scrubbing in circles. Shampoo goes downward through the hair, in the direction it grows.
- Heat on the cap. A flat iron near the knots melts the sealant holding them.
- Sleeping on cotton. Friction at the nape, every night, for hours. Satin bonnet or satin pillowcase.
- Harsh adhesive removal. Peeling a glued lace off without remover tears knots out of the front hairline, which is the worst place to lose them. Taking a wig off properly covers it.
What to do about it now
- Stop washing it for a fortnight. Let it settle and see whether the rate drops.
- Switch to damp, end-first detangling. Fingers and a wide tooth comb only.
- Seal the knots. Turn the unit inside out, spray a knot sealer or a light coat of hairspray across the inside of the lace, let it dry fully. Repeat after every few washes.
- Seal any cut wefts. As above.
- Satin at night. Non-negotiable if the unit is long.
- Condition the lengths. Dry hair snaps, and snapped hair looks like shedding.
When it is the unit, not you
If a new unit sheds heavily from the first wash despite careful handling, it was not made well, and no amount of sealant rescues knots that were never tied tightly. Unsealed knots and unsealed wefts are the two corners most commonly cut on cheap units.
Construction quality is also what separates hair grades more than the hair itself does — raw versus virgin hair explains how to read a listing, and our raw collection uses double-drawn, sealed wefts for this reason. If a unit arrived faulty, our returns policy covers it provided it has not been installed or altered.
Shedding versus thinning
A unit that is losing hair evenly across the whole cap will read as a density drop long before it reads as a bald patch, which is why people often describe it as the wig “going thin” rather than shedding. If you are choosing a replacement, buying a density step up buys you more tolerance for this — the density guide explains what each percentage looks like, and Aria runs at 180% and 200% for exactly that reason. Our care page covers the maintenance routine that keeps either from thinning early.
