Hair extensions tie up cash differently from retail products: a salon needs the right shade in the right length on the day of the appointment, but a full catalog on the shelf is expensive. This guide gives a simple stocking and reorder method built around how salons actually use hair.
Demand follows the appointment book
Most installations need a move-up every 6–8 weeks, so the same clients return on a predictable cycle. That means demand is concentrated in a small number of shades and lengths, and it repeats. Start from your appointment history, not from a supplier's catalog: list the shades used in the last two months and rank them by packs consumed.
The ABC split
| Group | What goes in it | How to stock |
|---|---|---|
| A | 2–3 core natural shades in 16/18/20 inch | Deep stock, reorder on a fixed point |
| B | Popular blondes and one balayage line | Moderate stock, reorder fortnightly |
| C | Fashion shades and long lengths | Order against a confirmed appointment, use a color ring |
This matches the assortment logic in our MOQ and pricing guide: MOQ is usually set per length and shade, so grouping orders by A-group shades is the cheapest way to buy.
Set a reorder point, not a reorder date
For each A-group SKU: reorder point = average weekly packs used × lead time in weeks + safety stock. Lead time means production days after sample approval plus transit — check freight options before you assume a number. Our factory order checklist covers the approval steps that sit inside that lead time.
Keep quality drift out of reorders
- Retain the approved swatch, dye lot and grams per pack under the purchase order.
- Weigh and wash-test a sample from every new carton: incoming inspection checklist.
- Check cuticle alignment, which is what keeps clients happy after the third wash.
- Never substitute a shade without telling the client and updating the SKU record.
Seasonal planning
Wedding and event seasons pull more length and volume; summer pulls lighter shades and balayage. Place seasonal bulk orders early enough for production and freight, and keep the core A-group on a steady reorder regardless of season. The salon pricing guide explains how to re-price services when hair cost moves.
Frequently asked questions
How many packs should a salon keep on hand?
Enough to cover the appointment book for one full lead time plus a small safety buffer in A-group shades.
How often do clients need a move-up?
Usually every 6–8 weeks, depending on the method and growth rate; use it to forecast repeat demand.
Should salons stock tape-in and clip-in?
Yes if you both install and retail; keep them in separate SKU groups. Method comparison.
What causes stockouts most often?
Running out of one core shade while total stock still looks healthy. Track by shade, not by total packs.
