Lashilé Beauty: 34% more orders from advertising, up year on year in each of the six months

Lashilé Beauty sells beauty supplements through a seller account on Amazon.fr: Good Hair, Good Skin, Good Sun, Good Night and slimming gummies. We have managed its Amazon advertising since late March 2026.

In 2025, to stay profitable, the brand had cut its advertising budget by 40%: half the impressions, and lost visibility in search. In early 2026, sales were still falling: −13% in February and −16% in March versus the same months of 2025, just before we arrived.

Our brief: return to growth without hurting profitability.

We run its Sponsored Ads campaigns on three fronts:

• An account rebuilt, with no internal competition. When we arrived, defence and conquest were mixed, and several campaigns were bidding on the same searches. We rebuilt the account product by product: each search is now targeted only once.
• The searches that sell, held all day. Budget goes to the queries that convert. Good Hair ranks in the top 10 results for “pousse cheveux”, the most searched term in its niche.
• Profitability managed every month. Every report sets the target ROAS and TACOS; the next one says whether they were met. What does not convert is cut, like the sun care gift sets in June, and its budget goes back to the best sellers.

April to September 2026, versus the same 6 months of 2025 (before we arrived, Amazon.fr):

• Orders from advertising: +34%
• Orders: +19%
• Advertising revenue: +22%
• Total revenue: +16%
• ROAS: 3.01 versus 2.67 (+13%)
• Up year on year in all 6 months

The first month: April 2026

April 2026 versus April 2025:

• Advertising budget: −37%
• Orders: +16%
• ROAS: 3.22 versus 2.57; TACOS: 15.80% versus 27.10%
• Conversion rate: 13.53% versus 9.77%
• Advertising revenue: −21%, total revenue: +8%

One month is not enough to judge: full speed takes 4 to 12 months, depending on the account. Here, the growth held every month through September.
