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.

Great concept but needs improvement. I really love the idea of this app but it seems my experience is the same as most of the reviews. Almost every product that I searched for was not there and these were extremely common brands such as No7, Sure deodorant and The Ordinary. I also found that some products wouldnt come up with barcodes but when I searched manually they were there (but often with older packaging). Just not as smooth, user friendly and up to date as most would like.

Thanks for your review. If you scan a product and it doesn't automatically show up, it could due to some barcode may not be clear or UPC codes can be different for countries. If you type the product in manually and it still doesn't show, please kindly submit it as we are constantly growing our database! Cheers from Think Dirty!

An awesome idea for an app. The technical aspect is really quite good in terms of adding new products, making it really easy to capture data via the camera. However it's too early to use, hardly any of the items I scan are found, and none of the items that I have submitted seem to have actually been added (waited a couple of days), supposedly I need to email them my username, no thanks, that seems backward, either let me add new items for approval or don't. Will check back in a few months.

This app is great in theory but there is a lot wrong with it, it's not the easiest app to maneuver or understand, and an incredible amount of name brand products, including garnier and body shop products, just aren't listed. This means you have to search manually for them because the app doesn't recognise the barcode. I also found when searching multiple of the same products showing up, maybe because users have the ability to add products by barcodes not being recognised.
