Think Dirty is your ultimate skincare, beauty scanner, and ingredients checker—designed to help you decode labels and make safer choices. Loved by over 7 million users, our app makes learning about potentially toxic ingredients in your skin care and cosmetic products easy. Scan the barcode, and Think Dirty app instantly delivers easy-to-understand, trustworthy product ratings and ingredient analysis. Whether comparing products or scanning items in-store, Think Dirty empowers you to shop smarter and live cleaner. WHY THINK DIRTY? • Ingredient-Focused Ratings: Think Dirty® uniquely evaluates products based solely on their chemical content, not brand reputation or marketing claims. • No Greenwashing: We don’t consider environmental or social factors that can artificially lower a product’s toxicity rating – our focus is strictly on health-related impact. • Truly Independent: Think Dirty® remains unaffiliated with third parties, ensuring unbiased, consumer-first product assessments. TOP FEATURES: • Scan or Search Products Instantly: Compare over 2.6 million products – skincare, personal care, cosmetics, household, baby, and pet items – and get detailed health impact breakdowns. • Real-Time Rating (Premium & All Access): Instantly scan beauty, skincare, cosmetic, and household products for immediate ratings – no waiting required! • Personalized Ingredient Preferences (Premium & All Access): Pre-select allergens and ingredient preferences for a personalized shopping experience. You'll also receive alerts if carcinogens or harmful ingredients are detected in your viewed products. • Ingredient Checker & Alerts (Premium & All Access): Flag allergens or harmful ingredients ahead of time and get alerts if they're found in products you scan or view. • Curated Safe Product Lists (Premium): Browse categories such as Mineral Sunscreens, Vegan Makeup, SLES-free skincare, and more. • Ingredient Lookup Tool (Premium): Search any skin care ingredient to understand its safety, origin, and usage across products. • Dirty Meter®: Our signature visual rating system shows ingredient concerns, health impacts, and certifications at a glance. • My Bathroom Rating: Check how clean your current products are. Track your clean beauty progress over time. • Upvote Unrated Products: Help us grow the database by upvoting products that need a rating – especially useful for international or indie brands. • Shopping Lists: Save clean products you love and organize your wishlist. • Shop Now Button: Purchase directly from trusted retailers like Amazon, Sephora, The Detox Market, Well.ca, and more. • UPC + OCR Submissions: Can’t find a product? Use OCR to scan the barcode and ingredients label and submit. Contributors will receive a discount code and notification once the product is added!

Totally changed my life and my hair! Amazing App!!!

Before I had this app, I had NO idea that the “natural” products I was using for my post-surgery hair loss were actually 1) NOT natural at all and 2) making my hair loss MUCH WORSE!! I love that you can just scan the barcode of a product (or look it up by name) to find out if it’s healthy or not. My favorite feature is the ingredient analysis, though! It shows every ingredient in every product in their database (they’re still building up their database - they have 1.6 million products and counting!-but you can submit new products if they don’t already have the one(s) you want to check out ;) )and shows you exactly which ingredients are healthy, which are questionable, and which are dangerous (using their 0-10 rating system) AND, in an effort to educate people, it tells you the other names of each ingredient (ex. Water/aqua), why it’s in the product, why it’s good/questionable/dangerous, and their recommendations! I’m not getting paid for this review, I really just LOVE this app and think it’s AMAZING and LIFE-CHANGING! Bottom line: This app is INCREDIBLE and really focused on educating the public about what they’re using on their bodies- not on getting any kind of payout. From now on, I’m not going to use any beauty products if I haven’t checked them on Think Dirty, first!

Great App, Couple of Flaws

This is a great app and I love all the information on it! I use it all the time. I love the barcode scanner. I completely cleared out my bathroom of all the toxic beauty products I’ve been hanging on to for years. I also will go to Ulta and use the barcode scanner to scan products until I find a clean one. Two changes I would make. It drives me nuts that every time I open the app, there is a pop up asking me to sign up for notifications. I already pay for the app, why are you also trying to shove notifications down my throat outside the app with a pop up notification in the app? I try to limit all notifications on all apps across my phone and it is very annoying that I have to click out of a pop up EVERY time I open the app, even if I opened it one minute before to look something up! I finally denied notifications and now there is a separate pop up I need to click out of notifying me that I denied them. I don’t get it. I don’t know if this is something that can be changed per app or if it has more to do with phone settings, but turning autocorrect off on the search box would be nice. There are so many beauty companies with wacky names that are close to a normal word, so autocorrect takes over. For ease of use, it would be helpful for that to not happen, but not sure if that’s something the app makers can change.

BEWARE! Dirty sneaky, they got something they are hiding.

I have used the free and paid version of this app. Since 2013. I was pleased with the idea and function of this app, until… I went to look up help section because the barcode would not focus. The only option is to read their FAQ’s. Which is a nightmare since there is no question bar for you to ask. (Poor app development)You are also asked if the level of privacy you would like? I was prompt this question in google not in the app. And when I went to the app to ensure the correct setting was applied; there is no option. In addition to this privacy setting, they make it silver, gold, and Platinum. Guess what silver is the highest. No where in the world is silver deemed more valuable than gold or platinum . My point; if you don’t read and just click you have given them all access to 3 parties and selling of your info. Along with this, if you tap on to read privacy settings you are no longer given an option to select. Just shady way of doing business . I will not be renewing my subscription as they make it difficult to get help and can’t be trusted. Disappointing.

Thank you for sharing your experience with Think Dirty—we appreciate your feedback and are here to help clarify a few things. To make the most of our FAQ section, visit the Think Dirty Help Centre through the link at the bottom of our website. On mobile, tap the three lines at the top right to access the search bar if you want something specific. If you’d like to delete your account, it’s easy to do directly in the app. On iPhone, go to the Profile tab, tap Settings, then scroll down and select “Delete Account.” For Android, head to the Help Centre and search for “How to Delete an Account – Android” for full instructions. Once deleted, all your personal info—like your name, email, beauty quiz answers, phone number, or birthday (if provided)—is permanently removed from our system.

I like that you can search for a product by name, but I wish there was a way to sort products by quality and price (which I noticed the website doesn’t include and is an important aspect for most, how much is this 1 rated shampoo vs the 3 rated shampoo? - for those unfamiliar a lower rating means a better product) I’ve also noticed a lot of comments on the really low rated products were quite negative or indicated they would not purchase more and you’d have to scroll to find some positive reviews, but the app still shows that product with an 80% would use again with 4+ stars?? When most the upfront comments are negative? I’m not sure about the reviews section of this app. I definitely will be using this app to further look into potential products, but it’s not as useful with finding new ones as I hoped it would be. ......after perusing the app for another 30 min or so and cross checking it with “the best 10 hair care products for dry hair” so far were 6/6 being listed as 8 ratings aka very dirty. Now I expected some of the big name brands to not be the best for you, but literally all of them are listed as very dirty because they have a fragrance in them? I get that fragrance is a chemical but if all the other ingredients are green and they have one thing that’s an 8 I don’t think giving it an 8 rating is fair....
