Korea is painting its own nails

What people search for inside Daiso is collected every day: cosmetics, new items, recommendations, nails, perfume. Five words. For two years the top one was always cosmetics. In July and August this year, nails went past it.

The same months a year earlier read 29.2 for cosmetics against 26.7 for nails, with cosmetics ahead. This July: cosmetics 20.3, nails 25.3. The order has swapped.

What 셀프네일 actually involves

셀프네일 (doing your own nails) in Korea means gel nails done at home rather than at a salon. A base coat, colour over it, then a small UV lamp to cure it. It is set by light instead of left to dry, so a finish done on a desk still lasts weeks.

This used to be a hobby that stopped at the buying stage. Lamp, base, top coat, colour, remover, file. Buy the lot and you have spent several salon visits' worth. Which is why it ended at “it is quicker to just book the salon”.

A 5,000-won ceiling turns a kit into single bottles

Daiso's pricing does the work here. Every item in the chain is sold at one of six prices — 500, 1,000, 1,500, 2,000, 3,000 or 5,000 won — and the 5,000-won ceiling has not moved since 2006.

With that ceiling in place, nail supplies cannot be sold as a set. They have to be lined up one at a time: one gel, one base, one file. The gel polish is 9ml for 2,000 won.

What broke was the price of entry. A decision about assembling a whole kit became a decision about trying one 2,000-won bottle. Korean outlets report that a starter set can be put together in the 10,000–20,000 won range, which is less than one salon visit.

The constraint set the way of selling, and the way of selling set the height of the doorstep. The 5,000-won ceiling is a fact about unit size as much as about cheapness.

In the numbers, the swap is plain

August against August, cosmetics fell from 30.3 to 19.2, down 36.8%, and nails rose from 21.1 to 25.9, up 22.7%. Neither one moved on its own.

Averaged across a full year, though, nails barely moved at all (+3.1%). It is a summer word — up in summer, back down in autumn — so a yearly average flattens the swing. Cosmetics fell 44.5% over the same year. The swap is a stronger summer than last summer combined with cosmetics sliding all year. Nails did the pushing; cosmetics made the room.

Nails rise in summer because feet are bare, and drop once September comes. This September reads 25.1 for cosmetics against 15.3 for nails, so the old order is back. But last summer produced no swap. When the season is the same and the result is not, the season is not what changed.

What pushed people home was the price

On the pushing side, the reason is money. Salon prices in Korea keep climbing, and Korean outlets report that rising costs made treatments feel heavy enough to move interest toward cheaper self-nail products. The same thing is reported in the United States, where inflation is described as shifting the nail market from salons to home.

Stop there and it is a shape seen in every downturn: a service you used to buy becomes a tool you buy once and use yourself. Eating out falls and cooking at home rises in exactly this way.

But the price was not the whole of it

One line quoted in the coverage shifts the reading. “I like the art I did myself better than the salon's.” That is not framed as a saving. It is framed as a preference.

Korean reporting also describes self-nail settling in as a hobby rather than only a way to spend less. One detail that keeps appearing is the UV lamp left standing on the desk. A tool that never gets put away is not a household item; it is equipment for something being continued.

If saving were the only reason, it would end as soon as it was cheap. When it does not end, and the tools keep accumulating, what was replaced is not a price but a way of spending time.

Nails sit where you look at yourself all day

Why nails and not cosmetics? This part runs past the numbers, but the geography of the body makes it hold.

Make-up is visible to you only when you stand in front of a mirror. The face sits where its owner cannot see it, and is basically for other people. Hands are different. They stay inside your field of view while you type and while you eat. You look at them all day, long before anyone else does.

When you go out less and meet fewer people, the decoration aimed outward is cut first. What survives is the part you look at yourself. Cosmetics falling and nails rising on the same shelf is, most likely, that order showing up.

The two largest falls of the past two years fit: 모공 (pores) down 41% and 톤업 (tone-up) down 38%. Both are words that assume being looked at.

What to look at on the shelf in Seoul

For anyone shopping in Korea, this has a fairly concrete form. Nails at Daiso are no longer a corner of the cosmetics aisle. They are their own section. Worth noting:

• Gel is 2,000 won for 9ml. Colours are picked one at a time rather than bought as a set
• No sets exist, everything is single. If you already own the kit, you can top up only the colour you are missing
• The ceiling is 5,000 won, so lamps and removers fall inside it too, which fits the 10,000–20,000 won reported for a full starter set
• Popular colours go out of stock. Assume you will not know what is on the shelf until you are standing in front of it

The band under 5,000 won is the whole point. A bottle of gel or a small lamp is more than a pure one-coin store can make and less than a salon visit is worth, and that band is where these products sit. As something to carry home they are light, small and easy to explain.

The salon side had not shrunk

After this piece first ran, five nail-related words were pulled back over two years. One part of the account above was not supported.

The only word that rose is the salon one. The three home-side words all fell together. “It moved from the salon to the home” is not the shape the last two years of search take.

The −13.8% on 셀프네일 needs care. It jumped to 2.8 in June and July 2025, and the remaining 22 months sit in a band of 1.1 to 1.7. Drop the summer and compare January-to-May with January-to-May, and it reads +4.3%. The words that actually fell are 젤네일, 홈케어 and 네일아트.

네일샵 and 셀프네일 are not a matched pair to start with. One is a word for finding a shop, the other a word for finding out how; 네일샵 looks the same whether more people are going or more shops are opening. What happened on the shelf holds, but whether the material for it came out of salons cannot be settled this way.

What is left open is who is doing this, and whether salon traffic actually fell. Search volume reaches neither. Nails are not among the seed words on the video side yet, and the shopping breakdown carries no nail category. Add both and an outside line stands up in two to three weeks. The next piece starts there.

From the desk. When two numbers change places, the shelf has usually moved first. Daiso's nail section grew because somebody decided it should, and that decision was made by watching what was selling locally. If you are in Seoul, give the nearest Daiso ten minutes before you go to the shop you came for. Whatever is moving in Korea now is on that shelf before it is in any article.
