Inside Our 4,300 SKUs: Every Hair System Size, Density and Grey Blend

Quick Answer — Our 4,300 SKUs are not 4,300 random products. They are one system multiplied out: 8 base sizes (5x7 to 9x11), 7 densities (80% to 140%), 12 grey blends (5% to 95%), 124 colours and 5 base materials. Most combinations sit in US stock and ship in 1–2 days; anything outside the matrix is built to order in our own factory, including custom human grey hair.

One number tells you more about a supplier than any landing page: how many distinct units it can put in a box today. Here is exactly how ours adds up.

How 4,300 SKUs Multiply Out

Four decisions stack on top of each other. Pick a size, then a material, then a density, then a colour — and every level of every decision is a separate SKU on a shelf. That is the whole point: a supplier with 3 sizes, 2 densities and 10 colours can only serve the buyer who fits their grid. A supplier with the grid below serves almost everyone, from the shelf.

Base Sizes: 8 Steps From Petite to Extra Large

• 5x7 — Small/Petite: smaller heads, early temple recession
• 6x8 — Medium: where many brands stop stocking
• 6x9 / 7x9 — Regular/Average: the most common US sizes
• 7x10 / 8x10 — Large/Full Top: full crown coverage
• 8x11 / 9x11 — Extra Large: rarely held in stock elsewhere

Every size in the ladder is stocked, not made to order. If your measurement lands between sizes, the smaller base with clean edges wins — see how we size a base for a natural fit.

Densities: 7 Steps From 80% to 140%

• 80% / 90% — light, mature hairlines
• 100% / 110% — light to medium, the safest natural look
• 120% / 130% — medium, fuller and younger
• 140% — medium to heavy, maximum coverage

Density is the decision buyers most often get wrong on the first order — always match your own temples, and go one step lighter when unsure. The full logic sits in how to choose hair system density.

Grey Blends: 12 Percentages From 5% to 95%

5%, 10%, 20%, 30%, 40%, 50%, 60%, 65%, 70%, 80%, 90%, 95% — twelve stock blends, held in every popular size and density combination.

The fibre behind those percentages is a deliberate choice. Real grey hair has almost no pigment left, so it oxidises toward yellow in long storage and no wash reverses it. Our stock grey is synthetic memory fibre: it holds the exact shade you ordered, keeps its wave and cannot take dye. For blends of 70% and above it is the more stable material by a wide margin. The reasoning, plus when to choose real hair instead, is in grey hair systems: stock and custom.

Base Materials: 5 Families

Lace (French and welded Swiss) for the invisible hairline and the hottest climates. Monofilament — fine and welded — for durability through months of daily wear. Polyurethane skin for fast cleaning and a shaved-scalp look. Hybrids with a mono or skin centre and a lace front, where most best-sellers live. Each family has its own collection: lace, mono and thin skin.

The Custom Escape Hatch — Including Human Grey

Everything above describes the shelf. Behind the shelf sits our own factory in Qingdao, and it builds the combinations the matrix does not cover: a density between steps, a size beyond 9x11 — and human grey hair, which we deliberately do not stock but do build to order, because real grey cannot survive long warehouse life without yellowing. Custom human grey takes about 40 days, cut to your measurements before shipping. How the two routes compare: stock vs custom hair systems.
