If Wordle had a hair care edition, this would be it. Every day, we pick a mystery hair ingredient. You get 6 tries to guess it. With each guess, you receive color-coded clues about whether you’re getting closer — matching on category, safety tier, source type, and more.
It takes two minutes, teaches you something new about hair care ingredients, and is strangely addictive. Our regulars have gotten scary good at it.
How to Play Ingredient Investigator
The rules are simple:
- A new mystery ingredient drops daily — Same ingredient for everyone, resets at midnight.
- Type your guess — Start with any hair care ingredient you know.
- Read the clues — After each guess, tiles light up showing how close you are on five attributes: category, function, safety tier, source (natural/synthetic), and CG compatibility.
- Narrow it down — Use the clues to eliminate possibilities and zero in on the answer.
- 6 guesses max — Can you crack it before running out?
Think of it like a logic puzzle meets ingredient education. Each round teaches you a new ingredient’s properties, even if you don’t guess correctly.

Understanding the Clues
Each clue after a guess tells you something specific:
- Category match (green) — Your guess is in the same ingredient category (surfactant, humectant, silicone, etc.) as the answer.
- Function match — The ingredient serves the same purpose (cleansing, conditioning, preserving, etc.).
- Safety tier match — Same safety rating (A through D) as the mystery ingredient.
- Source match — Both are natural, both are synthetic, or both are semi-synthetic.
- CG match — Both have the same Curly Girl compatibility status.
A perfect guess lights up all five tiles green. A close miss might show 3-4 matches, telling you which attributes to adjust on your next try.
Why Knowing Ingredients Matters
Every round of Ingredient Investigator quietly teaches you the hair ingredient landscape. After a week of playing, you’ll know the difference between surfactants and emollients, which preservatives are controversial, and which natural ingredients are actually effective vs. just trendy.
This matters because the hair care industry relies on consumer confusion. When you can identify 50 common ingredients by name, function, and safety profile, you become an informed buyer who makes better product choices. Our Ingredients Encyclopedia is the perfect companion reference — look up any ingredient you encounter in the game to learn its full profile.
5 Ingredients You Should Recognize Instantly
If you’re new to the game, start by learning these five ingredients that appear in nearly every hair product:
- Sodium lauryl sulfate (SLS) — The most common harsh surfactant. Found in most conventional shampoos. Creates lots of foam but can strip natural oils. Safety: C tier.
- Glycerin — The most widely used humectant. Draws moisture from the air into your hair. Found in conditioners, leave-ins, and styling products. Safety: A tier.
- Dimethicone — The most common silicone. Creates a smooth, shiny coating on hair. Prevents moisture from entering or leaving the strand. Not CG-approved. Safety: B tier.
- Cetearyl alcohol — A fatty alcohol (the good kind). Softens and smooths hair. Present in nearly every conditioner on the market. CG-approved. Safety: A tier.
- Phenoxyethanol — The most common modern preservative. Replaced parabens in many formulations. Generally well-tolerated. Safety: B tier.
Once you know these five cold, you’ll have anchor points for the puzzle that make every game easier. When your clues say “same category as dimethicone,” you’ll instantly know to guess another silicone.
