shopping universes, on ChatGPT and Gemini

76%

of ChatGPT's advice answers name no brand (0% for Gemini)

84%

of Gemini's shopping answers name a retailer (2% for ChatGPT)

Tests run on 1 August 2026 on ChatGPT (GPT-5.5 Instant) and Gemini (Gemini 3.6 Flash), using prompts in French, with a new conversation for each prompt and only the first response analysed. Presence rate measures the share of prompts in which a brand is mentioned or recommended. 150 prompts were tested per AI, including 88 used in the rankings; 55 advice prompts and 7 brand-review questions were analysed separately. Retailers and distributors are excluded from the brand rankings. Product ranges are attributed to their parent brand (Dercos to Vichy, Kelual and Anaphase to Ducray, Elseve to L’Oréal Paris). “First mention” indicates the share of responses in which the brand is named first. Results should be read as an indication of brand visibility at the test date.

Each Radar is a snapshot of brand visibility in AI at the date of testing. As models evolve regularly, results are not strictly comparable from one issue to another.

Ranking: Hair loss

Base: 13 product-choice or problem prompts ranked, 15 advice prompts analysed separately.

How users search. More than half of the prompts are worried questions, not purchases: “how can I tell if my hair loss is just seasonal or something worse?”, “I've been losing hair by the handful when brushing since September”. The rest look for a treatment or a supplement, for a man whose hair is thinning, after childbirth, or for fine hair that a treatment must not make greasy.

ChatGPT is cautious: on shopping prompts, 38% of its answers name no brand at all and point to a doctor or a blood test. When it does name brands, Ducray dominates (46%, named first in 23% of answers), ahead of Vichy (38%, never first) and the minoxidil Alopexy (23%). Gemini always names brands: Ducray in 100% of answers, René Furterer in 85% (against 8% on ChatGPT), Forcapil and Klorane in 77%, and supplements such as Vitalfan (54%) or Anacaps (46%).On hair loss, a brand first has to win ChatGPT's trust, as it often prefers to recommend no one.

What it means for a brand. This is a reassurance universe. Brands that explain (seasonal loss or not, when to see a doctor, what a treatment can do) become credible sources for ChatGPT, where it stays silent today. On Gemini, the gap between presence and first place shows the battle is about proof of efficacy.

Ranking: Damaged hair after summer

Base: 23 product-choice or problem prompts ranked, 6 advice prompts analysed separately.

How users search. They describe a state, with images: “my hair is like straw after the beach”, “my lengths are super rough from the salt”, “the pool chlorine has dried out my hair”. They hesitate between mask, oil and leave-in, and add a constraint: bleached, coloured or curly hair, or fine hair that a mask weighs down.

Kérastase is the most named brand on both AIs (70% on ChatGPT, 100% on Gemini) but almost never first (4%). On ChatGPT, first place goes to Garnier (65% presence, named first in 35% of answers) and Klorane (57%, 26%). Gemini names nearly the whole L'Oréal group (L'Oréal Professionnel 87%, L'Oréal Paris 83%), puts René Furterer first in 17% of cases and names a retailer in 100% of its answers (Sephora, Monoprix, Nocibé, Carrefour).After summer, Kérastase is everywhere but rarely chosen: Garnier and Klorane are the brands ChatGPT most often names first.

What it means for a brand. The users' vocabulary (straw, salt, chlorine, frizz) is the one to find in product pages and FAQs. A premium brand has to justify its price with proof of use to move from simple presence to first mention, and be present at the retailers Gemini names in every answer.

Ranking: Sensitive scalp

Base: 16 product-choice or problem prompts ranked, 11 advice prompts analysed separately.

How users search. They pile up constraints: “oily roots but a sensitive scalp”, “dandruff and a sensitive scalp”, “curly hair and an itchy scalp”, “a soothing shampoo that won't damage my colour”. They also want to understand: why the scalp turns red or itches after washing, which ingredients to avoid, whether fragrance-free really is better.

This is the most dermatological universe. On ChatGPT, Ducray is the reference: named in 88% of answers and first in 56%, ahead of Bioderma (88%, 25%) and Eucerin (69%). Gemini names the same brands (Bioderma 88%, Ducray 81%) but more often puts Vichy first (31%, against 0% on ChatGPT). On advice questions, ChatGPT names no brand in 91% of cases, while Gemini names Ducray and La Roche-Posay in all its answers.On sensitive scalps, Ducray has the most first mentions on ChatGPT, but Gemini more often names Vichy first.

What it means for a brand. Dermatological proof (tolerance, supervised tests, short formulas) makes the difference. Advice questions (ingredients to avoid, itching after washing) are open territory on ChatGPT: the brand that answers them best becomes the source.

Ranking: Routine by hair type

Base: 20 product-choice or problem prompts ranked, 10 advice prompts analysed separately.

How users search. Prompts start from the hair type and its problem: fine hair that gets greasy or flat, curls “without the crunchy effect”, frizz when it rains, grey hair turning yellow, colour that fades. Many are about the order and way to apply products: it is the routine, more than the product, that is asked for.

ChatGPT is highly scattered: Kérastase is the most named (45%) but never first, and the top spot is shared by Garnier, L'Oréal Professionnel and Bioderma (15% each). Curl specialists (Les Secrets de Loly, Bouclème) and John Frieda appear in 20% of answers. Gemini establishes Kérastase (95%), L'Oréal Paris (75%) and Klorane (60%), names Aroma-Zone in half its answers and a retailer in 95%.On routines, no brand is named first more than once in six: the territory is won hair type by hair type.

What it means for a brand. Specialists (curls, grey hair, fine hair) have a real card to play: routine pages by hair type, with application order and mistakes to avoid, answer exactly these questions and can take a niche brand to the top spot.

Ranking: Pharmacy or salon

Base: 16 product-choice or problem prompts ranked, 13 advice prompts analysed separately.

How users search. The question is about channel and price: “an effective mask without paying salon prices?”, “supermarket or pharmacy shampoo for damaged hair?”, “why do salon products cost three times more?”. Users weigh supermarket, pharmacy and salon, often with a budget in mind.

Bar and first figure: presence rate (Mentioned). Light part of the bar and greyed figure: first mention (recommendation signal).

This is the universe where ChatGPT names the most brands on advice (54% of its advice answers name at least one, against 24% on average): as soon as channels are compared, it gives examples. It puts L'Oréal Paris (44%, named first in 25% of answers) and Garnier (44%, 19%) on top, ahead of Klorane and René Furterer. Gemini places five brands level at 50% (Kérastase, Garnier, Klorane, René Furterer, L'Oréal Paris) and names a retailer in 81% of its answers.When users compare channels, mass-market brands take the top spot on ChatGPT, ahead of salon brands.

What it means for a brand. A brand has to state clearly where it is sold and why it is worth its price: honest comparisons, equivalences between ranges, proof of results. This is the ground of comparative content, which both AIs readily pick up.

Presence is not preference

The presence rate measures the Mentioned level of the V.M.R. methodology. First mention, the share of answers in which the brand is the first one named, is a recommendation signal: stronger than simple presence, it does not mean the AI explicitly claims to recommend the brand. Across the 88 ranked prompts, the gap between the two is the real measure of the work to be done.

Kérastase is the most present brand on Gemini (68%) but is named first in only 11% of answers there, and 5% on ChatGPT. René Furterer is named in 53% of Gemini's answers against 18% on ChatGPT. Garnier and Ducray are the brands ChatGPT most often names first (16% and 15%).

Advice or purchase: two AIs, two logics

On the 55 advice questions (“does back-to-school stress increase hair loss?”, “which ingredients should I avoid with a reactive scalp?”), ChatGPT answers with no brand at all in 76% of cases, and even refers users to a doctor on hair loss. Gemini names brands in every answer and names a retailer in nearly two advice answers out of three. On shopping prompts, Gemini names Sephora in 66% of answers and Nocibé in 52%, while ChatGPT almost never names a retailer.

The 7 review questions, left out of the ranking

Seven prompts asked for an opinion on a specific product (René Furterer Triphasic ampoules, Ducray Anastim serum, Kérastase Nutritive mask, Olaplex No. 3, Klorane shampoos, Vichy Dercos, Garnier Fructis). ChatGPT stays on the brand asked about in 6 answers out of 7. Gemini brings competitors in 5 answers out of 7 (up to 8 brands for Olaplex and Garnier Fructis) and names a retailer in 6 out of 7. On Gemini, a question about your product is also a showcase for your competitors.

Key takeaway. In hair care, Kérastase is the most present brand on Gemini (68%) and is named in 36% of ChatGPT's answers, but is named first there in only 5% of cases. René Furterer goes from 18% on ChatGPT to 53% on Gemini. ChatGPT stays cautious on hair loss and advice (76% of advice answers without a brand), while Gemini always names brands and names a retailer in 84% of its shopping answers.
