Hair Systems Explained: Bases, Bonds and What They Cost You

A hair system is an object: a made base carrying hair, attached to your scalp with tape, adhesive, clips or a fitted vacuum seal. It is not a treatment, it changes nothing about hair loss, and it comes off when you take it off — which is the one genuine advantage it holds over a tattoo.

Almost nothing about the modern market is published in a form anyone can check, so this note leans on a 2016 review in the International Journal of Women's Dermatology, the most detailed published description this site could verify. Its price figures are a decade old and are labelled as such throughout. They are quoted because they are sourced, not because they are current.

The bases, cheapest to most involved

What a system costs and how it looks are mostly decided by its foundation. The 2016 review sets out four kinds and published US price bands for them at the time:

• Wefted — rows of hair sewn to a base. The most common and least expensive; the review published $60 to $300.
• Net — a mesh base with hair knotted in by hand. More natural-looking and more expensive; $300 to $1,000 in that review.
• Monofilament cap — a fine transparent nylon lace with hair tied in individually, allowing more natural movement and styling, with the hairline section made deliberately irregular to resemble a real hairline. The review published $200 to $2,000.
• Custom vacuum base — built from a plaster mould of your own scalp into a silicone or polyurethane shell. The review notes the process can take up to six months to do properly.

Those are 2016 figures from a US review, and no comparable current published range exists that this site could verify. Treat them as a shape — the spread between a stock base and a hand-knotted one — rather than as today's price.

Hair itself is the other variable. The review notes systems are made from synthetic fibre or human hair, that hand-sewn looks more natural than machine-sewn and costs more, and that human hair comes from several countries with European hair at the expensive end.

How it stays on, and what that does to skin

Attachment is where systems stop being a clothing decision. The 2016 review lists the options: velcro or adjustable straps and bands; taping, for ease of placement and removal; bonds, for longer periods of adhesion; and clips, for temporary attachment.

Then it names the cost. Bonding and taping may lead to contact dermatitis, the review says, especially from wig adhesives such as acrylates, and it cites reported cases of allergic contact dermatitis to cyanoacrylate. That is a documented skin reaction to the glue, not to the hair, and it is the reason a patch test before a first bond is a reasonable thing to ask for.

Newer systems, the review adds, adhere across the whole area of the base rather than only around the perimeter, which makes the cap feel more part of the scalp. More adhesive contact is more comfortable and more skin exposed to the adhesive at once.

Integration pieces, for thinning rather than bald

If there is still hair, there is an option between a full system and nothing. The review describes integration wigs, where your own hair is pulled through perforations in the base so that the piece and your hair are worn together — the same logic as a density plate, achieved with an object instead of ink.

Worth separating from hair extensions, which are a different thing and carry a documented risk. The review cites a case study of four women who developed patches of scalp alopecia at extension attachment sites, and notes that traction alopecia of that kind is initially non-scarring but may lead to scarring or permanent hair loss. Pulling on hair that is already thinning is not a neutral act.

The maintenance nobody mentions at the fitting

Systems have a service life and a service schedule, and both arrive after the purchase. The 2016 review puts standard inexpensive wigs worn daily at replacement every three to six months, and good human-hair wigs at three to four years.

Between replacements there is re-taping or re-bonding at whatever interval your adhesive dictates, cleaning, and periodic refitting as the hair underneath changes. None of that is hidden exactly, but it does not usually appear on the same page as the headline price, and it is the reason a system is a subscription rather than a purchase.

What a system does not do

It does not slow hair loss, protect the hair underneath, or change anything medical. The hair on the base is not growing and the hair under it carries on doing whatever it was doing. A system is clothing for the head — useful clothing, sometimes transformative clothing, but clothing.

There is one thing it does that neither pigment nor powder can: it covers a scalp with no hair left at all, at full density, on the day you put it on. For extensive loss, alopecia areata that has cleared large areas, or hair loss during chemotherapy, that is not a small advantage — and the 2016 review is largely written for exactly those situations rather than for pattern baldness.

Against a tattoo, and against a bottle

The three cosmetic routes trade off on exactly one axis that the marketing never uses: what it costs to stop.

The pigment column is the one with a blank in it and a laser at the bottom. That asymmetry is the argument for trying a removable route first, and it is set out at length on what scalp micropigmentation costs.
