By model
How each assistant handled Hair Color questions.
Reading the 45 answers model by model shows how differently the three assistants treat the same hair color questions. On the most consequential behavior — whether to send the buyer to a professional at all — the rate ranged from 86.7% (ChatGPT) down to 60% (Claude), a 27-point gap on an identical question set.
Across the 15 hair color answers it produced, ChatGPT recommended hiring a professional in 86.7% of them and suggested a DIY approach first 0% of the time. It named a specific provider in 0% of answers (about 0 distinct providers per answer) and included price or cost information 0% of the time. ChatGPT asked a clarifying question before answering in 53.3% of cases, warned about red flags or scams in 20%, and told the buyer to verify credentials in 0%, averaging 418 words per answer. On the remaining cues it told the buyer to check reviews in 20%, pointed to case studies or a portfolio in 20%, and framed the choice around local proximity in 13.3%; a selection-criteria checklist appeared in 46.7% of its answers and a recommendation to gather multiple quotes in 0%.
Across the 15 hair color answers it produced, Claude recommended hiring a professional in 60% of them and suggested a DIY approach first 0% of the time. It named a specific provider in 0% of answers (about 0 distinct providers per answer) and included price or cost information 13.3% of the time. Claude asked a clarifying question before answering in 53.3% of cases, warned about red flags or scams in 13.3%, and told the buyer to verify credentials in 0%, averaging 270 words per answer. On the remaining cues it told the buyer to check reviews in 6.7%, pointed to case studies or a portfolio in 13.3%, and framed the choice around local proximity in 13.3%; a selection-criteria checklist appeared in 46.7% of its answers and a recommendation to gather multiple quotes in 0%.
Across the 15 hair color answers it produced, Gemini recommended hiring a professional in 60% of them and suggested a DIY approach first 0% of the time. It named a specific provider in 0% of answers (about 0 distinct providers per answer) and included price or cost information 20% of the time. Gemini asked a clarifying question before answering in 0% of cases, warned about red flags or scams in 26.7%, and told the buyer to verify credentials in 0%, averaging 273 words per answer. On the remaining cues it told the buyer to check reviews in 6.7%, pointed to case studies or a portfolio in 13.3%, and framed the choice around local proximity in 6.7%; a selection-criteria checklist appeared in 20% of its answers and a recommendation to gather multiple quotes in 0%.
Taken together, ChatGPT is the assistant most likely to route a hair color buyer to a professional (86.7%) and Claude the least (60%). ChatGPT produced the longest answers, at 418 words on average. No model named a specific provider in more than 0% of answers.
Where they disagree
The behaviors where the choice of model changes the answer.
Question-level model disagreement is 16.7% — the average pairwise rate at which models received different binary codes across questions and behaviors. The observed rate spreads below are a separate measure showing where which assistant a hair color buyer happens to ask matters most:
- Asks a clarifying question: from 0% (Gemini) to 53.3% (ChatGPT) — a 53-point spread.
- Recommends hiring a professional: from 60% (Claude) to 86.7% (ChatGPT) — a 27-point spread.
- Gives selection criteria: from 20% (Gemini) to 46.7% (ChatGPT) — a 27-point spread.
- Gives price or cost information: from 0% (ChatGPT) to 20% (Gemini) — a 20-point spread.
- Warns about red flags or scams: from 13.3% (Claude) to 26.7% (Gemini) — a 13-point spread.
The widest single gap — asks a clarifying question, 53 points — means a hair color buyer can receive materially different guidance on the same question depending only on which assistant they happen to open, so any visibility strategy built on a single model's behavior describes only part of the hair color market.
Where they agree
The points of near-consensus in Hair Color.
On other behaviors the three models move almost in lockstep — the points of near-consensus for hair color, where all three landed within a few points of each other:
- Suggests a DIY approach first: 0% across all three models.
- Names a specific provider: 0% across all three models.
- Tells the buyer to verify credentials: 0% across all three models.
- Recommends multiple quotes: 0% across all three models.
Measured question by question, the three assistants coded a response the same way most consistently on "suggests a DIY approach first" (identical coding in 100% of questions) and least consistently on "asks a clarifying question" (20%).
Every behavior, measured
All twelve coded behaviors for Hair Color, averaged across the three models.
The behaviors AI models reproduce most often for hair color are recommends hiring a professional (68.9% on average), gives selection criteria (37.8%) and asks a clarifying question (35.5%); the rarest are recommends multiple quotes (0%), tells the buyer to verify credentials (0%) and names a specific provider (0%). Each figure below is the share of a model's 15 answers in which the behavior appeared at least once, averaged across the 3 models with the full per-model range in parentheses:
- Recommends hiring a professional: 68.9% on average (ChatGPT 86.7%, Claude 60%, Gemini 60%) — a 27-point spread.
- Gives selection criteria: 37.8% on average (ChatGPT 46.7%, Claude 46.7%, Gemini 20%) — a 27-point spread.
- Asks a clarifying question: 35.5% on average (ChatGPT 53.3%, Claude 53.3%, Gemini 0%) — a 53-point spread.
- Warns about red flags or scams: 20% on average (ChatGPT 20%, Claude 13.3%, Gemini 26.7%) — a 13-point spread.

Trust signals
How well the models protect the hair color buyer.
Beyond whether to hire, the rubric codes how carefully each assistant protects the hair color buyer once a decision is made. Telling the buyer to check reviews or ratings appeared in 11.1% of answers on average. Verifying credentials or certifications appeared in 0%. Warning about red flags or scams appeared in 20%.
On structuring the decision, a selection-criteria checklist showed up in 37.8% of answers on average and a recommendation to gather multiple quotes in 0%. The single least-reproduced protective signal for hair color is "tells the buyer to verify credentials" at 0% on average — the clearest opening for content that supplies it, since the models are not yet reliably surfacing that guidance on their own.
Referral behavior
Do AI models name Hair Color providers?
For service providers the decisive question is whether these systems name anyone at all. Across 45 hair color answers, a specific provider was named in 0% of responses on average — roughly 0 distinct providers per answer. In practice the assistants behave far more as an explanatory layer than as a referral engine for hair color: visibility comes from being the reasoning a model reproduces, not from being the named recommendation.
The question set
What these 15 Hair Color questions cover.
The 15 questions behind every percentage on this page form a frozen hair color (beauty services; buyer hiring decisions for this specific service) buyer-intent benchmark. Each was put to all 3 models once, with identical wording, so the rates above describe how the assistants handled this exact hair color question set — not a general prior or a hand-picked subset. The full list is shown earlier on this page; the coded percentages are what those specific questions produced.
How to read this
A note on the numbers.
A percentage here is the share of a model's 15 answers in which the behavior appeared at least once — not a confidence score. Because each model answered every question exactly once on 2026-07-05, the figures describe this specific hair color question set and snapshot rather than a general prior. The full protocol and coding rubric are documented in the study methodology.
Methodology
A controlled snapshot, documented end to end.
15 frozen benchmark questions, one expected response per model per question (ChatGPT API (gpt-5-mini), Claude API (claude-sonnet-5), Gemini API (gemini-3-flash-preview)), collected 2026-07-05 and coded against a fixed 12-behavior rubric. The pipeline validates the schema, recomputes aggregates and reports consistency issues. AI outputs vary with model version, location and time, so the figures describe this edition's exact sample and measurement window. Read the full methodology →
