The Setup
Olaplex and K18 sell into the same customer on TikTok Shop - someone chasing healthier, stronger hair - at similar price points. A year ago, K18 actually had the bigger TikTok Shop business. Today, Olaplex has lapped it more than 3x over. Here's what twelve months of creator, product, and content data show - and why.
The Headline Numbers
| Sept 2025 | Peak | Aug 2026 | 12-Month Change | |
|---|---|---|---|---|
| Olaplex | $13.1K GMV | $502.8K (May '26) | $246.7K | ~19x growth |
| K18 | $58.4K GMV | $121.6K (Nov '25, BFCM) | $72.2K | ~1.2x (essentially flat) |
K18 started with 4.4x the GMV Olaplex had. By November 2025, Olaplex had already caught up. From there it kept climbing — multiple months well into six figures — while K18 has spent the whole year oscillating in a $40K–$122K band with no clear upward trend.
Creator & Affiliate Depth: Roster Size Is the Whole Game
Olaplex's active creator roster grew 5x; K18's grew 2.2x from a higher starting point. Olaplex went from 622 active creators in September 2025 to 3,113 by August 2026. K18 started bigger (1,427 active creators) but only grew to 3,154 — meaning Olaplex closed almost the entire gap in roster size while growing its GMV nearly 19x in the process.
The top-15 highest-earning videos tell the sharper story. Pulling the best-performing video for each brand over the full 12 months:
- Olaplex's top 15 videos generated a combined ~$213,800 in attributed revenue, spread across 12 different creators — all with follower counts between 3,960 and 120,873. Not one mega-influencer appears in the list.
- K18's top 15 generated ~$120,900 — about 43% less — spread across 11 creators, but with a far wider (and more telling) follower range: from 2,107 all the way up to 3.2 million.
That last number is the one worth sitting with. K18's single most-followed creator in its top 15 — 3.21 million followers — generated $3,366, the second-lowest revenue figure on the entire list. Meanwhile, a nano-creator for Olaplex with 8,101 followers ("madsion__") appears three times in the top 15 and generated $58,354 combined — more than any single K18 creator, including the one with 42x the following.
Reach and revenue are not the same thing on TikTok Shop, and this pair of brands is the cleanest possible illustration of it. With TikTok Shop's recent affiliate commission cuts squeezing creator payouts, building a broad, efficient affiliate roster matters even more.
Product-Level Data: One Brand Keeps Feeding the Machine
Olaplex's Top 5 Products (Aug 2026, 30-day GMV):

K18's Top 5 Products (Aug 2026, 30-day GMV):
| Rank | Product | GMV | Units Sold | Price |
|---|---|---|---|---|
| 1 | AirWash Dry Shampoo (4oz) | $16,488 | 345 | $47.79 |
| 2 | TripleBright Oxidation Defense Purple Shampoo | $14,157 | 363 | $39.00 |

| 5 | FutureIQ™ Biomimetic Hair Longevity Serum | $5,924 | 48 | $123.42 |
K18's #5 product launched just three weeks before this snapshot (Aug 10) and was already top-5 — a genuinely strong signal for that one SKU, even though the brand's overall catalog isn't expanding at anything like Olaplex's pace.
Olaplex nearly tripled its active TikTok Shop catalog in a year — from 27 products in September 2025 to 81 by August 2026. K18's catalog barely moved: 21 products to 25 over the same period. Olaplex launched new sets and SKUs roughly every 4–6 weeks throughout 2026 (a Curl Hydrate + Define Set in May, a Shine Serum Oil Mist in June, an LIVE Exclusive Favorites Set in August); K18's most recent new listing - a FutureIQ™ biomimetic serum (only launched August 2026), and most of its top sellers (the AirWash dry shampoo, the Leave-In Molecular Repair Mask) date back to 2024.
The August 2026 top-seller snapshot shows the same split in miniature. Olaplex's top product that month (Nº.7 Bonding Oil, $36.2K) was outsold within the same catalog by newer entrants — the Curl Hydrate + Define Set, launched in May, was already the #2 earner three months later. K18's top seller was still AirWash dry shampoo, the same hero SKU driving the brand's best video a year earlier in September 2025.
On pricing, K18 is actually the stronger story. Its average selling price climbed from $44.28 (Sept '25) to $53.97 (Aug '26) — real premiumization, holding or raising price even while GMV stayed flat. Olaplex's average price held steady in the low-to-mid $30s–$40s throughout, suggesting its growth came from volume and reach, not from charging more.
Content Cadence: The Flywheel, Quantified
Olaplex scaled video output more than 100x; K18's barely moved at all. Olaplex went from 27 videos posted in September 2025 to a peak of 4,352 in May 2026 — and even its "quiet" months (Aug '26: 3,327 videos) dwarf anything in K18's range, which held steady between roughly 941 and 1,692 videos a month for the entire year with no real trend up or down.
Revenue-per-video tells you which brand is converting that activity into dollars. Averaging the months after each brand's ramp-up period, Olaplex generated roughly $98 per video versus K18's $54 — nearly double the efficiency, on top of posting far more volume. Put another way: Olaplex isn't just posting more content, each piece of content is pulling its weight better, too.
Why This Happened
Put the three data sets together and the mechanism is obvious:
- Olaplex kept expanding its catalog, giving a growing creator base fresh products to feature every few weeks.
- More products + more creators meant more videos — and the video volume curve is almost a straight line up.
- More videos from a broad, low-follower creator base outperformed K18's smaller number of bets on higher-follower creators, because distributed nano/micro content converts better than occasional mega-reach content in this category.
K18 isn't doing anything wrong, exactly — it has a strong hero product (AirWash), a loyal niche of creators, and rising average order values. It just hasn't built the same repeatable engine. Its TikTok Shop business looks like a series of good moments rather than a compounding trend.
What This Means If You Sell on TikTok Shop
Building a creator-affiliate engine like Olaplex's takes shop operations, creator management, and content working together — that's what our TikTok Shop agency services are built for.
- Reach isn't revenue. A 3.2M-follower creator and an 8K-follower creator can produce wildly different returns — budget creator partnerships by conversion history, not follower count.
- Catalog velocity feeds content velocity. New SKUs give your existing creator base new things to talk about; a static catalog caps how much content can be made about you, no matter how many creators you recruit.
- Creator roster growth and video volume should move together. If your creator count is climbing but video output isn't, something is broken in activation — recruited creators who don't post aren't an asset yet.
- A single viral hit is not a strategy. K18's best video of the year (4.1M views) didn't out-earn Olaplex's typical month six months later. Diversify across many smaller creators rather than betting on repeat mega-influencer moments.
- Rising AOV without rising GMV is still worth tracking. K18's pricing power is a real asset — it just needs volume (more creators, more content) to go with it.
