Teaching AI Your Salon's Voice

You've probably tried using ChatGPT to write an Instagram caption or an email to your clients. And if you're like most salon owners I talk to, you read the output and cringed. It probably used words like "elevate," "unlock," or "pamper yourself." It didn't sound like you. It sounded like a generic brochure from 2014.

I don't cut hair. I run ads and build funnels for salons, and I've watched a few hundred of them try to get new clients. When I look at the campaigns that fail, the copy is almost always the culprit. It's either too dry, or lately, it's obviously written by AI that hasn't been given any guardrails. Your clients know how you talk. When your marketing suddenly sounds like a robot, you lose trust instantly.

The problem isn't the AI. The problem is the brief. If you just ask an AI tool to "write an email about our new balayage special," it has to guess what your salon sounds like. It defaults to the average of all salon marketing on the internet—which, frankly, isn't very good. To fix this, you have to teach the AI your specific salon brand voice.

Why AI Defaults to "Robot Mode"

When you use AI without a brand voice guide, it pulls from its vast training data to predict the most likely words to follow your prompt. Because so much beauty industry marketing relies on clichés, the AI regurgitates those clichés. It thinks every salon wants to "transform your look" and "unleash your inner beauty."

You have to actively train the AI out of these habits. You need to give it rules. Think of the AI as a new front-desk hire. You wouldn't just tell them to "answer the phone." You'd give them a script, tell them what phrases to avoid, and explain the vibe of the salon.

The Cost of Generic Copy

When your ads and emails sound like everyone else's, they blend into the background. In a crowded feed, generic copy gets scrolled past. We know that repeat salon clients spend 67% more than first-time visitors [1]. But to get those first-time visitors in the door, your marketing has to resonate. It has to feel authentic. If your ad copy sounds like a robot wrote it, potential clients will assume your service is just as impersonal.

The Brand Voice Document: Your AI's Rulebook

To get good output, you need to create a simple, one-page Brand Voice Document. This is the reference file you will feed to the AI every single time you ask it to write something for you.

Here is what your Brand Voice Document needs to include:

How to Train the AI (The Copy-Paste Prompt)

Once you have your Brand Voice Document, you don't just ask the AI to write. You have to set the context first.

Here is the exact prompt structure we use when generating AI-personalized follow-up emails or ad copy for our clients:

System Prompt: Act as an expert copywriter for a hair salon.

I am going to give you our Brand Voice Document. You must follow these rules strictly for all future responses in this chat.

[Paste your Brand Voice Document here]

Acknowledge that you understand these rules by replying with a one-sentence summary of our tone, and do not write anything else yet.

Once the AI acknowledges the rules, you can then give it your specific task.

A Worked Example: The Balayage Promo

Let's look at the difference this makes.

Without the Brand Voice Document: Prompt: "Write a Facebook ad for our $50 off balayage special." AI Output: "✨ Unlock your hair's true potential! ✨ Pamper yourself this weekend with our exclusive balayage special. Elevate your look and embark on a hair journey with our expert stylists. Book now for $50 off and transform your confidence!"

With the Brand Voice Document (using the rules from the table above): Prompt: "Write a Facebook ad for our $50 off balayage special. Follow the brand voice rules." AI Output: "Want lived-in color that actually lasts? We specialize in low-maintenance balayage that looks good for months, not weeks. This week, we're taking $50 off your first session. Click below to grab a spot before they're gone."

The second version sounds like a real person. It's direct, it focuses on the benefit (low-maintenance), and it avoids the cringe-worthy filler words. This is the kind of copy that works when you're trying to figure out what a salon should spend on ads per month and need those ads to actually convert.

Quick Reference: Brand Voice Checklist

Before you use AI to write your next email or social post, make sure you have defined:

• Your core identity: Who are you and who is your ideal client?
• Your tone: Are you funny? Serious? Educational? Casual?
• Your vocabulary: What specific terms do you use for your services?
• Your banned words list: What AI clichés do you hate?
• Your formatting preferences: Do you use bullet points? Short paragraphs? Emojis?

FAQ

How do I stop AI from using words like "elevate" and "unlock"?

You have to explicitly ban them. Create a "Banned Words" list in your prompt or Brand Voice Document. Tell the AI: "Never use the following words under any circumstances: elevate, unlock, pamper, transform."

Can AI write in my exact personal voice?

Yes, but you have to show it examples. Along with your Brand Voice Document, paste in 3–4 emails or captions you've written yourself that you really like. Tell the AI: "Analyze the tone and sentence structure of these examples, and mimic this style."

Do I have to paste the rules every time?

If you are starting a new chat window, yes. However, tools like ChatGPT Plus allow you to set "Custom Instructions" that apply to every conversation, or you can create a custom GPT specifically for your salon that has your brand voice rules permanently baked in.

Why does my AI copy still sound slightly off?

AI is a starting point, not a finished product. It might get you 80% of the way there, but you still need to read it out loud and edit it. If a sentence feels clunky, rewrite it. The goal is to save time, not to completely outsource your brain.
