Inventory by store type

Inventory management for Shopify hair care brands

Hair care brands juggle shampoo, conditioner, and styling lines across multiple sizes and scents, often made by a co-packer with its own minimums. SteadyShelf keeps reorders on schedule per variant without the spreadsheet juggling.

The inventory problems hair care brands run into

  • Shade and formula proliferation. A single shampoo line can split into 3 sizes and 2 scent variants, turning one product into 6+ SKUs to track and reorder separately.
  • Private label and contract manufacturing. Many brands use a co-packer with minimum batch sizes, so you cannot just reorder 20 units when you are low, you may have to commit to 500 or 1,000 units per run.
  • Shelf life on natural formulations. Products with botanical oils, no parabens, or cold-pressed ingredients often have shorter real-world shelf lives than mass-market synthetics, so overordering ties up cash in stock that may expire unsold.
  • Viral and influencer-driven spikes. A single TikTok or influencer mention can spike demand for one specific variant overnight, and if that SKU is also your slowest-moving size normally, you may be caught flat-footed.
  • Packaging and component lead times. Pumps, caps, and labels sometimes come from a different supplier than the liquid formula itself, so a stockout can happen because of a $0.10 pump, not the product.

Seasonality and demand

Hair care sees steady baseline demand with real peaks around holiday gifting season, especially gift sets and travel sizes in November and December. Many brands also see a bump in late spring and early summer as people switch to lighter formulas or prep for humid weather, and a back-to-school bump in August and September for dorm-size and travel-size products. Dry, cold-weather months often push deep conditioners and anti-frizz products. Plan reorders for your co-packer's slowest lead time before these windows, since minimum batch sizes make last-minute top-ups hard, and build safety stock into your SteadyShelf settings for your top sellers heading into Q4.

Suppliers, lead times and minimums

Hair care brands typically order from one of three supplier types: contract manufacturers or co-packers who produce your formula to a private label spec, white-label suppliers who sell an existing formula under your branding, and component suppliers for pumps, caps, and labels. Co-packers often require minimum batch runs in the hundreds or low thousands of units per SKU, and lead times stretch out when a formula needs lab approval or a new ingredient sourced. Overseas packaging suppliers often take several weeks to produce and ship, and domestic co-packers usually need lead time booked in advance for production slots, so planning your order-by dates matters more than chasing a faster supplier.

Worked example

Say you sell a 10oz argan oil shampoo, and it sells an average of 6 units a day. Your co-packer's lead time is 21 days and you keep 5 days of safety stock, so your reorder point is 6 x (21 + 5) = 156 units. You want 35 days of cover total, you currently have 90 units on hand and 0 on order, so your order quantity is 6 x (21 + 35) - (90 + 0) = 336 - 90 = 246 units. Your co-packer's minimum batch is 300 units, so SteadyShelf rounds the suggested order up to 300 and flags the minimum on the draft purchase order.

Try it with your own numbers in the reorder point calculator, or size your buffer with the safety stock calculator.

A simple system to start this week

  1. List every SKU separately, including each size and scent variant, not just the base product name.
  2. Get real lead times from each supplier or co-packer, including time for labels and packaging components if they come from elsewhere.
  3. Set a reorder point for each SKU using daily sales times lead time plus a safety buffer, especially for your top sellers.
  4. Build a rough content calendar awareness: flag any SKUs tied to upcoming influencer posts, launches, or seasonal pushes so you order ahead.
  5. Track expiry dates for short-shelf-life formulas outside SteadyShelf, in a spreadsheet or on the batch label.
  6. Review the weekly reorder email and adjust quantities manually when you know a spike is coming that past sales data would not predict.

How SteadyShelf fits hair care brands

SteadyShelf forecasts demand per variant, which matters in hair care since a 4oz and 16oz bottle of the same formula sell at very different rates. It rounds suggested orders to your co-packer's batch minimums and case packs, then drafts and emails the purchase order once you approve it. It does not track expiry dates or batch numbers, so for short-shelf-life natural formulas you still need to manage that separately, and it will not handle transfers if you split inventory across a 3PL and a retail studio.

FAQ

Does SteadyShelf track expiry dates on my shampoo and conditioner batches?

No. SteadyShelf does not track lot numbers or expiry dates. It forecasts demand and tells you when to reorder based on sales velocity. For products with a shelf life, like leave-in conditioners or anything with natural oils, keep expiry dates in a spreadsheet or on the product label itself, and do a manual visual check when stock arrives. Order in quantities you will actually sell before expiry, not just the cheapest case pack.

I use a 3PL and also store some stock at my studio. Can SteadyShelf handle transfers between them?

Not directly. SteadyShelf manages inventory for one Shopify store location and does not move stock between warehouses or retail locations. If you run a 3PL plus a studio stockroom, treat the 3PL as your main inventory location in Shopify and handle any transfers to the studio outside the app.

How does SteadyShelf handle a shampoo that comes in 4oz, 8oz, and 16oz sizes?

Treat each one as its own SKU with its own sales history. A 4oz and 16oz bottle of the same shampoo sell at different rates and often have different lead times if they come from different fill runs. SteadyShelf forecasts and reorders each variant separately, so the small size will not get buried under the big size's numbers.
