Year-End Peak Season: What Supplies Should a Lash Salon Prepare, and How Much Is Enough?

From around October onward, the pace of work in beauty salons across Europe often begins to change noticeably.

After the summer holidays come autumn break, Halloween, year-end company parties, Christmas, and then New Year. This is also the time when clients tend to pay more attention to their appearance, take more photos, attend more events, and want their lashes and brows to stay beautiful throughout the festive season.

For lash artists, this can be one of the best periods of the year for revenue. At the same time, it is also when problems can easily happen: a fully booked schedule but not enough supplies, plenty of clients but not enough of the right lashes, running out of adhesive over the weekend, or having to place urgent orders at higher cost.

After working through many year-end seasons and running a salon, I have learned one important lesson: preparing for peak season does not mean buying as much as possible. What matters is knowing which products need extra stock, which ones need only a small backup, and which ones you should avoid overstocking.

Don’t start with the question: “How many lash trays should I buy?”

Start with your appointment calendar.

A common mistake among newer salons is to look at the supplies currently on hand and make a rough guess: “A few more trays should probably be enough.”

In reality, the amount of stock you need depends on at least four factors:

• your average number of clients per week;
• the proportion of full sets versus infills;
• the lash styles your salon performs most often;
• how long it normally takes for a new order to arrive.

For example, a lash artist seeing around 20–25 clients per week will have very different supply needs from a salon with three artists serving 60–80 clients per week.

Before placing my peak-season orders, I usually review the previous 4–6 weeks of appointments and estimate demand for the next 6–8 weeks.

A fairly practical formula is:

Stock required = average weekly usage × number of peak-season weeks + 20–30% buffer stock.

For essential products that could prevent you from taking clients if they run out, the buffer may need to be even higher.

1. Lash extensions: stock according to what your salon actually uses

Lash extensions are probably the category that requires the largest amount of preparation, but they are also one of the easiest products to overstock.

A salon does not need the same quantity of every curl, thickness, and length.

Look at your own client history first.

If 70% of your clients usually choose C curl and CC curl, there is little reason to stock L curl or M curl in the same quantities.

Similarly, if most clients use lengths between 8–13 mm, trays containing 15–17 mm lashes only need to be kept in moderate quantities.

For a solo lash artist serving around 20–25 clients per week during peak season, I would normally want at least:

• 2–3 backup trays of the curls used most frequently;
• 1–2 trays of less frequently used curls;
• backup stock of popular lengths such as 8–13 mm;
• only moderate quantities of very short or very long lengths.

If you use mixed-length trays, check your fastest-moving lengths carefully. A tray may still look fairly full, while the 9–12 mm rows are already almost empty.

That is exactly when you think you still “have lashes in stock,” only to realise once the client is lying on the lash bed that you do not have enough of the lengths needed to complete the design.

For salons with 2–3 lash artists, instead of simply multiplying everything by two or three, look at which products are heavily used across the whole team.

Best-selling lash lines should have a shared salon backup stock, in addition to the trays currently being used at each workstation.

For example:

• core lash lines: approximately 4–6 backup trays;
• medium-use lines: 2–3 trays;
• special styles: 1–2 trays.

These numbers are not fixed standards. A salon specialising in Volume lashes will consume stock very differently from one where most clients choose Classic lashes.

The important question is not “How much does another salon buy?” but “How much does my salon actually use each week?”

2. Lash adhesive: always have backup, but don’t overstock

If there is one product I never want to run out of in the middle of the Christmas season, it is lash adhesive.

However, adhesive is also not something you should buy in excessive quantities.

Lash adhesive has a limited working life and specific storage requirements. Buying six bottles may look economical, but if you cannot use them in time, the money saved from ordering in bulk may be smaller than the value of the adhesive that eventually deteriorates.

For a full-time lash artist, a sensible minimum is usually:

1 bottle currently in use + at least 1 unopened backup bottle.

During periods when my appointment calendar is consistently full, I prefer to keep 2 backup bottles, particularly when delivery to the salon normally takes several days.

Salons with multiple lash artists should calculate adhesive stock according to each artist’s actual usage rather than applying one general number to everyone.

Another important point is that winter in Europe changes more than just the outdoor temperature. The indoor environment also changes because heating systems are running continuously.

Indoor humidity can be significantly different from summer conditions.

Before peak season, check:

• room temperature;
• humidity;
• the curing speed of the adhesive you are using;
• how the adhesive is stored after opening.

Having enough adhesive is not enough if it does not perform properly under your salon conditions. This can affect both working speed and lash retention.

3. Gel pads, tape, and disposable supplies: stock slightly more than you think you need

These products are relatively inexpensive per unit, but running out of them can disrupt an entire working day.

I usually calculate the quantity according to the expected number of clients and then add a 20–30% buffer.

For example, if a salon expects to serve around 100 clients in one month:

• Gel pads: approximately 120–130 pairs;
• spoolies: 120–150 pieces if you provide one to each client;
• micro brushes: calculate the average number used per client and add around 25%;
• lip applicators or cleansing applicators: use a similar calculation;
• tape: always keep at least 2–3 backup rolls in addition to the ones currently being used.

I am generally comfortable keeping a little more stock in this category because usage is easier to predict and the products are usually less sensitive to storage time than lash adhesive.

4. Cleansing and lash preparation products

The festive season is also when clients tend to wear makeup more frequently.

Foundation, eyeshadow, eyeliner, mascara, and skincare products around the eye area can all mean that cleansing before a lash appointment takes more time.

So do not prepare only lashes and adhesive.

Check your stock of:

• lash shampoo;
• primer, if it is part of your salon procedure;
• saline solution or other suitable cleansing products;
• cleansing brushes;
• cotton pads and other cleansing accessories.

I personally like using lash shampoo to cleanse clients’ lashes and brows because it provides gentle cleansing. I also use Hang's Studio lash primer to remove oils and residue. For essential products like these, you can keep at least 1 bottle currently in use and 1 unopened backup bottle.

Salons with a high client volume may want enough stock for approximately 4–6 weeks of operation, plus one additional backup unit.

5. Remover: you may not use it often, but you should never run out

Remover is a good example of a product that may not be used every day, yet is difficult to replace properly when you suddenly need it.

During the festive season, you may have clients who:

• want to remove an old set before getting a new design;
• come to you with lashes done by another salon;
• have twisted or heavily grown-out extensions;
• want the extensions completely removed after an event.

A small salon usually does not need to keep a large quantity of remover.

One product currently in use and one backup product is generally more practical than buying several and storing them for too long.

6. Tweezers: always have a Plan B

A good pair of tweezers can last a long time.

But one drop onto the floor can affect your entire working day.

During quieter periods, you may be able to work around the problem. But when your pre-Christmas calendar is fully booked from morning until evening, losing your favourite pair of tweezers becomes a very different issue.

I therefore recommend that each lash artist has:

• at least 2 isolation tweezers;
• 2 application tweezers suitable for their main technique.

For artists working with Volume lashes, it is also worth having an additional fan-making tweezer that you have already tested and know you can work comfortably with.

Do not wait until your main tweezers are damaged before trying the backup pair for the first time.

7. Brow service supplies need their own stock calculation

If your salon also offers Brow Lamination, brow tinting, or other brow services, do not let lash extensions take all your attention.

Before peak season, check your supplies of:

• lifting and setting solutions;
• brow tint;
• oxidant;
• brushes;
• micro brushes;
• plastic wrap;
• spoolies;
• cotton;
• cleansing and aftercare products.

For chemical products with a limited shelf life after opening, pay attention to the date the product was opened, not only the expiry date printed on the packaging.

This is a small detail that is very easy to overlook when the salon becomes busy.

8. Don’t place one enormous order before Christmas

Buying all your supplies for three months at once may sound sensible.

I generally prefer not to do that.

Actual demand can always change.

A particular lash style may suddenly become popular. A curl you expected to use heavily may not be requested as often as expected. Or one product may be consumed much faster than you predicted.

A safer approach is:

One larger order at the beginning of the season + smaller planned restocking orders.

For example:

At the beginning of October, check your inventory and replenish your main stock.

At the beginning or middle of November, review actual usage.

At the beginning of December, place your final major restocking order before the busiest Christmas period.

This approach helps reduce both the risk of running out and the risk of carrying unnecessary stock.

When preparing an order, you can also open a specialist lash supply store such as Hangstudioshop.com and use the categories as a checklist: lashes, adhesives, tweezers, gel pads, tape, cleansing products, and disposable supplies.

I find this type of category-by-category check useful because it often reveals small items that are easy to forget before submitting an order.

The key point remains the same: do not order according to a shop’s product catalogue; order according to your salon’s actual usage data.

9. Create a minimum stock level for every important product

This is probably one of the most useful changes I have made when managing salon supplies.

Instead of waiting until something is almost finished before ordering more, every important product should have a reorder threshold.

For example:

As soon as stock reaches that threshold, the product goes onto the next order.

This is particularly useful in November and December because you no longer need to work on clients while trying to remember how many gel pads are left in the cupboard.

10. Check the things that are not inside your “lash kit”

Another mistake I have seen in many salons is preparing professional lash supplies carefully while forgetting everyday operational essentials.

Before peak season, also check:

• towels;
• disposable bed covers, if your salon uses them;
• surface disinfectant;
• gloves;
• masks;
• rubbish bags;
• paper towels;
• tool-cleaning products;
• work lamps;
• replacement bulbs or backup power sources;
• charging cables and necessary accessories.

An expensive bottle of adhesive may be important, but sometimes the thing that causes trouble in the salon is simply... running out of paper towels on a Saturday afternoon.

11. Stock preparation is only half of the story

Peak season does not only put pressure on your inventory.

It also puts pressure on the lash artist.

If you normally see four clients per day but try to fit in six or seven every day throughout December, the issue is no longer simply whether you have enough lashes in stock.

Your neck, shoulders, back, eyes, and ability to concentrate all have limits.

A lash set completed at 9:00 in the morning when you are fresh may not always have the same quality as one completed at 19:00 after six consecutive clients.

When opening additional year-end appointments, remember to include:

• breaks between clients;
• time to eat;
• time to clean and reset your workstation;
• time for late-arriving clients;
• buffer time in case a treatment takes longer than expected.

A schedule that is 100% full does not necessarily generate more profit than one that is 85–90% full.

If appointments are scheduled too tightly and one delay affects the rest of the day, the income from one additional client may come at the cost of a poorer experience for the next four clients.

12. Don’t forget year-end delivery schedules

Another factor that many salons remember only when it is already too late is delivery time.

As Christmas approaches, parcel volumes increase. Weekends, public holidays, and courier operating schedules can also make delivery times less predictable than usual.

For that reason, essential supplies such as:

adhesive + core lash trays + gel pads + tape + cleansing supplies

should not be reordered only when you have enough stock left for a few more days.

If you regularly order supplies from Hangstudioshop.com or any other supplier, pay attention to the actual delivery times you experienced with previous orders.

Use that information to determine an appropriate minimum stock level for your salon.

A salon that normally receives orders within 1–2 days can operate with different inventory levels from a salon where deliveries regularly take close to a week.

Quick checklist before peak season begins

Before November starts, I would check at least the following categories:

Lash extensions: enough stock of your best-selling curls, thicknesses, and lengths.

Adhesive: one bottle currently in use plus unopened backup stock.

Disposable supplies: gel pads, tape, spoolies, micro brushes, and applicators.

Lash preparation: lash shampoo, cleansing brushes, primer, and any other products used in your salon procedure.

Tools: your main tweezers plus tested backup tweezers.

Lash removal: enough remover in good condition.

Brow services: check solutions, tint, and shelf life after opening.

Salon hygiene: enough cleaning and disposable supplies for at least several weeks.

Restocking schedule: know when the next order should be placed instead of waiting until supplies are almost finished.

Finally: prepare enough, not as much as possible

The year-end period can be one of the most profitable times of the year for a lash salon.

But it can also become several exhausting weeks if your inventory and appointment schedule are not prepared in advance.

If there is only one principle to remember, I would choose this:

Keep more stock of inexpensive, fast-moving products that are difficult to replace; be cautious when stocking products with a limited shelf life after opening; and always have a backup for any tool you cannot work without.

Before placing your order, spend around 20 minutes opening your supply cupboards, checking each section, and writing down the actual quantities you have.

Then create your restocking list.

You can use the categories on Hangstudioshop.com as a checklist to see whether you have forgotten any supply group, but the final quantity you order should always be based on your own client volume and actual consumption rate.

The goal is not to enter the Christmas season with the biggest possible stockroom.

The goal is that when your final client before the holidays lies down on the lash bed, you still have the right lashes, the right adhesive, and the right tools you need — without having to pick up your phone and wonder:

“Has that order arrived yet?”
