Growth plan for UKLASH, 3 Oct 2026
Scale spend. Hold CAC.
UKLASH already owns the proof: Lash Growth Serum 1ml has 53,262 reviews at 4.8. The plan turns that into a steady stream of new ads, tests the winners hard and holds CAC at the £14.40 guard line while spend scales.

- Target CAC
- £14.40
- New ads a week at peak
- 20
- Creators live by week six
- 10
- Test spend, six weeks
- £24,000

10 chapters, then the gates and every number’s source.
01 The number
One number to protect: CAC at £14.40, on a serum with 53,262 reviews
The one number to protect is target CAC: £14.40. It is 0.6 of the £24.00 ceiling, which comes from a £30 order, a 40% margin and one repeat order. The order value and margin are my guesses until UKLASH's own numbers replace them.
Protect
Target CAC: £14.40 on a first purchase
Ceiling = average order × margin × (1 + repeat orders): £30 × 40% × (1 + 1) = £24.00. Guard line = 0.6 × £24.00 = £14.40. Across the ranges: £2.21 to £268.65.
Three moves
- Kill losing ads early, so spend moves to the few that hold the £14.40 line.
- Lead with the serum's 53,262 reviews while tests on sets and supplements run in parallel.
- Report daily CAC, so a drift past £14.40 is caught the same day.

02 Variety
Lash serum, Tubing Mascara, hair supplements: three kinds of ad
Each ad concept has to carry one reason to buy and one product: the lash serum's rating, the Tubing Mascara try-on, or the hair supplements routine. One variable changes per test, so a loser tells us which part failed, not just that it failed.
| Reason to buy | Proof you already have | Ads (proposed) |
|---|---|---|
| Longer, fuller-looking lashes | 85% longer and 80% fuller-looking lashes | 6 |
| 53,262 reviews | 53,262 reviews | 3 |
| Money-back guarantee | unhappy with the results after 12 weeks of use, we will give your money back | 3 |
| Instant lift | 82% saw visibly lifted lashes instantly | 2 |
| Savings on your order | 20% off your first order. 15% off forever. | 2 |
| Conscious recipe | Free from parabens and oils. Vegan and safe to use with lash extensions and contact lenses | 1 |
| Applied in seconds | Apply our Eyelash Serum in less than 5 seconds | 1 |
| Total | The ad concepts tab | 18 |


Each row is a reason to buy that the brand already has proof for. The count is how many of the ads carry it: a reason with a single ad is a bet, not a pattern, and the next batch of concepts moves toward the reasons that win.
03 Disturbances
Seven risks, two of them straight from UKLASH's offer stack
| Disturbance | Likelihood | Impact | Owner | Gate (proposed) |
|---|---|---|---|---|
| Results lines drift from UKLASH's own wording, such as 82% lifted or 85% longer | Med | High | Both | Every results line matched to the claims sheet before launch; no unmatched ad stays live. |
| Offer stack confuses buyers: 10% off first order versus 20% off with 15% off forever | Med | Med | Your team | One first-order offer per ad, checked weekly against the live site. |
| The Lift & Boost Set shows 2 reviews, so ads sent there convert below the serum page | High | Med | Me | Test traffic goes to the serum page first; a bundle gets spend only if its CAC is under £14.40. |
| Tracking cannot split first orders from subscription orders, so CAC reads wrong | Med | High | Your team | Event tracking specced and matched against real orders before week two spend. |
| Creators miss the weekly video count and ad output stalls | Med | Med | Me | Creator videos a week at 14, then 28, then 42; a miss triggers replacement creators. |
| Test CAC runs above £14.40 in the early weeks while winners are still unknown | High | Low | Me | Total test spend stays within £24,000; any ad above the £24.00 ceiling is stopped. |
| Money-back guarantee covers the serum but not the hair vitamins, and ads blur the two | Low | Med | Both | Every ad naming the guarantee names the product it covers; checked on the claims sheet. |
Scores are my read from outside the company, re-scored in week one with your data. Each risk has one owner and one gate that can be checked with a number, so nobody has to argue about whether it happened.
04 The ceiling
Ceiling £24.00, guard line £14.40, set before the first UKLASH test
| Line | Value | Status |
|---|---|---|
| Average order | £30 (range £4.20–£199.00) | Assumption Range from the site product prices (Published); the midpoint is a guess |
| Gross margin | 40% (range 35–45%) | Assumption Replace in week one |
| Repeat orders after the first | 1 (range 0.5–2) | Assumption Replace with cohort data in week one |
| Margin per customer, all orders | £24.00 | Calculated Average order × margin × (1 + repeat orders) |
| Guard line for CAC | £14.40 | Calculated 0.6 × the margin per customer |
The math, with the assumed lines
Ceiling = average order × margin × (1 + repeat orders): £30 × 40% × (1 + 1) = £24.00. Guard line = 0.6 × £24.00 = £14.40. Across the ranges: £2.21 to £268.65.
Range across the assumptions: £2 to £269.
The £30 order, 40% margin and one repeat order are guesses. The £24.00 ceiling is arithmetic on them. Week one replaces all three with UKLASH's own order data.
The ceiling is a range, not one number: the most a new customer can cost before shipping and packaging, which I do not have. Replace the guessed lines with yours and every figure below recalculates.
05 Test ramp
Six weeks of tests, £24,000 in total, before the serum scales
| Week | New ads × budget / ad (proposed) | Weekly test spend | Cumulative | Creators posting | CAC target (proposed) |
|---|---|---|---|---|---|
| 1 | 12 × £250 | £3,000 | £3,000 | 0 | £14 |
| 2 | 12 × £250 | £3,000 | £6,000 | 2 | £14 |
| 3 | 12–20 × £250 | £4,000 | £10,000 | 4 | £14 |
| 4 | 12–20 × £250 | £4,000 | £14,000 | 6 | £14 |
| 5 | 20 × £250 | £5,000 | £19,000 | 8 | £14 |
| 6 | 20 × £250 | £5,000 | £24,000 | 10 | £14 |
Weeks one and two run 12 ads each at £250, £3,000 a week. Weeks three and four run 12–20 ads, £4,000 a week. Weeks five and six run 20 ads, £5,000 a week. Cumulative spend is £6,000 by week two and £24,000 by week six. Proposed.
The math. Week 1: 12 × £250 = £3,000; Week 2: 12 × £250 = £3,000; Week 3: 16 × £250 = £4,000; Week 4: 16 × £250 = £4,000; Week 5: 20 × £250 = £5,000; Week 6: 20 × £250 = £5,000. Total £24,000 (96 ads × £250). A range such as 12–20 counts as its midpoint.
Weeks one and two test what the brand already has, rewritten per reason to buy. From week three, creator videos enter paid only after they beat their own account median. A range of new ads counts as its midpoint in the spend column.
06 Volume
Lash serum hooks need volume: 20 to 80 concepts a month
20 concepts give 2 winners and £18,000 added a month; 80 concepts give 8 winners and £72,000. Hit rate and spend per winner are guesses. More concepts mean more chances at a cheap serum hook.
| Concepts tested / month | Hit rate (assumed) | New winners / month | Spend each winner holds (assumed) | Added spend at target CAC |
|---|---|---|---|---|
| 20 | 10% | 2 | £300 / day | £18,000 / month |
| 40 | 10% | 4 | £300 / day | £36,000 / month |
| 60 | 10% | 6 | £300 / day | £54,000 / month |
| 80 | 10% | 8 | £300 / day | £72,000 / month |
The math. 20 concepts × 10% = 2 winners × £300 × 30 days = £18,000 a month; 40 concepts × 10% = 4 winners × £300 × 30 days = £36,000 a month; 60 concepts × 10% = 6 winners × £300 × 30 days = £54,000 a month; 80 concepts × 10% = 8 winners × £300 × 30 days = £72,000 a month.
The hit rate and the spend each winner holds are placeholders. The first thirty days of tests replace them with real numbers, and the table is recalculated the same day.
07 Allocation
The £100,000 budget follows what UKLASH already sells best
- Lash Growth Serum 1ml ads and creators
- £45,000
- 45%
- Tubing Mascara and lash sets
- £25,000
- 25%
- Hair serum and hair supplements
- £20,000
- 20%
- Retargeting and the subscribe offer
- £10,000
- 10%
This splits the £100,000 budget (Proposed). The serum leads because its 53,262 reviews give the strongest hook.
The math. 45% × £100,000 = £45,000; 25% × £100,000 = £25,000; 20% × £100,000 = £20,000; 10% × £100,000 = £10,000. Sum 100% = £100,000.
This split is a proposal. It moves toward scaling as winners prove out, and toward testing when fatigue shows.
08 Channels
Meta first, then the places UKLASH shoppers already look
| Channel | Open when (proposed) | Why wait |
|---|---|---|
| Meta | Week one, with 12 ads live | Fastest read on hooks for the serum; creator videos double as ads. |
| TikTok | Once a creator hook wins on Meta | Lash and hair routines are native to short video. |
| Google brand search | When Meta spend holds the £14.40 line | Catches shoppers who search UKLASH after seeing creator videos. |
| Week one, tied to the first-order offer | UKLASH already offers 10% off a first order for an email sign-up. | |
| YouTube Shorts | After week six, if creator output holds | Reuses the same creator videos with no extra shoot. |
A channel opens when its condition is true, not when the calendar says so. Until then the budget stays where the CAC is earned.
09 Payback
Payback is the constraint, and UKLASH offers subscribe and save 20%
Payback is the real constraint. At a CAC of £5 the first order leaves £19.00. At £15 it takes repeat orders and leaves £9.00. At £25 it never pays back and leaves −£1.00; at £35, −£11.00. Subscribe and save only helps if CAC clears that line.
Cumulative margin per customer, order by order, before CAC: £12.00, £24.00.
| CAC (scenario) | First-order margin | Year-one margin | Left after CAC | Payback |
|---|---|---|---|---|
| £5 | £12.00 | £24.00 | £19.00 | First order |
| £15 | £12.00 | £24.00 | £9.00 | After repeat orders |
| £25 | £12.00 | £24.00 | −£1.00 | Never: stop |
| £35 | £12.00 | £24.00 | −£11.00 | Never: stop |
The math. CAC £5: £24.00 − £5 = £19.00 left; pays back: First order; CAC £15: £24.00 − £15 = £9.00 left; pays back: After repeat orders; CAC £25: £24.00 − £25 = −£1.00 left; pays back: Never: stop; CAC £35: £24.00 − £35 = −£11.00 left; pays back: Never: stop.
Read each row left to right: the margin of the first purchase, the margin over the whole horizon, what is left after CAC, and the purchase on which the CAC is earned back. A scenario that never pays back is a stop, not a test.
10 Scope
Scope: ads, creators and claims sheet; not the product or the site
Covers
- Meta ad testing on the serum, Tubing Mascara and hair lines
- Creator sourcing, briefs and the weekly video count
- A claims sheet built from UKLASH's own product wording
- Daily CAC, weekly learnings, monthly cohort payback
Doesn’t
- Product, formula and pricing decisions
- Building event tracking: I spec it, your team ships it
- Customer service and shipping
- Approving health claims beyond UKLASH's own wording
What this plan covers is what I can change inside the ad account and the creator program. Everything outside it is named on the right so nobody assumes it is handled.
Gates, written before spend, so stopping isn’t a negotiation.
| Day | Keep going if (proposed) | Stop or change if |
|---|---|---|
| Day 14 | Twelve ads a week live, at least one ad under the £24.00 ceiling, tracking matches orders | No ad under £24.00 after £6,000 of tests |
| Day 30 | CAC trending toward £14.40 and at least one winner reused in new creator cuts | CAC still above £24.00 after £14,000 of tests |
| Day 60 | Ten creators live and CAC at or under £14.40 on spend above test level | CAC above £24.00 for two straight weeks |
| Day 90 | CAC at £14.40 or under, payback inside repeat orders, budget scaling toward £100,000 | Payback reads Never on live numbers |
Each gate is checked on its day with the numbers in the daily and weekly reports. If the stop condition is true, the spend stops and nothing renews until we talk.
What exists, what’s missing, and the order that’s forced.
| Piece | Exists today | Missing | Forced order |
|---|---|---|---|
| Claims sheet | Results lines such as 85% longer and 80% fuller | One approved sheet for every ad | 1st |
| Creative | Serum rated 4.8 with 53,262 reviews | Ad concepts and a hook library | 1st |
| Creators | Lash, brow and hair lines for different personas | Creators, briefs and a weekly video count | 2nd |
| Landing pages | The Lift & Boost Set page with 2 reviews | Pages built per ad concept | 2nd |
| Reporting | Offers: 10% off first order, subscribe and save 20% | Order tracking split by offer | Week 1 |
The order is forced on purpose: creative and creators come first because they are what moves CAC, and everything else waits for that data.

Every figure on this page is listed here with where it came from. Fact means read on the site. Assumed and Proposed are Danilo’s own numbers, to be replaced in week one. Calculated is plain arithmetic on those, with the formula shown next to it.
Month one is where it starts.
Week one: I send the claims sheet draft, the first 12 ads and the tracking spec for your team, and the first two creators are briefed. Daily CAC reporting starts with the first spend, against the £14.40 guard line.
