About this app

Think Dirty is the easiest way to learn about the potentially toxic ingredients in your cosmetics and personal care products. It’s an independent source that allows you to compare products as you shop. Just scan the product barcode, and Think Dirty will give you easy-to-understand info on the product, track dirty ingredients, and shop for cleaner options.

• Search by Keyword or Barcode Scanning: Our database lists over 850,000 cosmetics and personal care products from Canada and the U.S.

• Personalized Ingredient Preferences (Premium): Save time by pre-selecting your Allergens, Ingredient preferences and personalizing your shopping experience. Ingredient alerts will be presented if we find flagged ingredients in the products you viewed.

• Search by Ingredient (Premium): Unlock to get detailed information about its usage, health impact, sources, and which products contain such ingredients.

• Search by Curated Categories (Premium Feature): Unlock to access our curated speciality lists such as Mineral Sunscreens, SLES-Free Skincare, Vegan Makeup

• Expiry Date Tracker: Is that mascara still good to use, but don't remember how long you have had it? Now you can keep track of its expiry date on your Bathroom Shelf. Enter Open Date and Shelf Life, and you will never put expired products on your face again!

• Dirty Meter®: A comprehensive rating is given, along with detailed (but easy-to-understand) information on ingredients, certifications, and health impacts.

• My Bathroom Rating: Keep track of what’s already in your bathroom. Learn your current bathroom rating, and track your progress on “cleaning” it up.

• Upvote Non-Rated Products: Let your voices be heard! Upvote, and we will aggregate user responses and reach out to brands on users’ behalf to encourage them to get their products verified and rated.

• Shopping Lists: Save products and make shopping faster and easier.

• Shop Now: Buy products directly from Amazon.com, Amazon.ca, Well.ca, Sephora.com, and Amazon.co.uk.

• UPC Submission: Are we missing a product? Use your device's camera to scan its barcode and capture the list of ingredients with OCR, then submit it to us. For registered users who submit products, we thank you with a discount code to use our beauty box subscription. And will notify you once they are in our database.

Used this app for years but now that most things are behind a pay wall, the amount it costs is not worth it. How often do you really need to look up products in here?! The only time I need to use it is when I'm buying a new product and that's every few years. The fact that even things like recalls are behind a paywall is scammy to me. Not to mention, when I did use it in the past, many items I searched were not in here

Hi there! We understand your frustration. As a small team, subscription helps us improve the app while staying true to our mission of ingredient transparency. Many features remain free, and our Premium & All Access plans are optional. Your support helps us grow. Thank you for being part of the journey! We hope you'll give the app another try. 🙏🏼

I REALLY want to love this app, BUT when I'm looking at face primer and click on "our picks" I expect alternatives NOT lotion, cleanser, mascara, and anything other than primer! Also, when scanning bar codes to check items like toothpaste, shampoo, hair gels, and such I am having to enter so much information & it definitely takes more than "just a minute" of my time. KEEP TRYING UPDATE: It took 3 YEARS and 5 months for a reply that said they're working on it ... 😶

Good to have community reviews, otherwise pushy on products and subscription. Other apps provide similar ingredient info for more products without pushing shopping. Worse, the shop buttom doesn't even link to the product! Nor does a premium subscription elimate sponsored content. Also, it's sus that products on sponsored content also happen to be products with the best 'scores,' even though products with worse 'scores' have all well-rated ingredients. Seems scammy.
