  • Totally changed my life and my hair! Amazing App!!! Jun 23, 2020

    By Becscan
    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!

    I only have the free version, and I don't frequently find the need to sort by paid category, as I usually do my own research and use this as a tool to help with specific products, not as a primary search platform. It is really helpful, but I wish it had less general explanations for some ingredients. I understand it is based off the listing from the manufacturer, but some of the ingredients are under an umbrella listing rather than specifically listed. Ex. Fragrance vs Essential Oils

  • THE BEST APP EVER- Mar 26, 2019

    By kemyers
    I was so unaware of what I was bringing into my home. My cleaning products (all purpose cleaner & dish soaps, laundry soaps, etc.), body products (deodorant, shampoos, conditioners, facials, makeup, etc.) THEY WERE ALL TOXIC- and I had no idea. Some of these chemicals effect human hormones, skin sensitivity, and some chemicals lead to cancer & I didn’t even know they were in my home. I was uneducated which is the exact reason I am writing this review- once you know, you know & I guarantee once you know you will want better for your husband, your kids, yourself, and even the dog. TAKE ACTION! Download this app and use it to your best ability the app has a ranking scale from 0-10. 0 being the healthiest 10 being the MOST toxic. This is judged based upon the chemicals and products in your cleaners from home cleaners to body products too. All of my home products & body products were sitting at like an 8 or 9- which is really scary- Now you know, and YOU should download this app && change your life.

    Good tool... Things to note though: To get all the perks, you'll need to buy the add-on (i didn't and still love it); Lots of products out there haven't been rated (but you can submit them); Some ingredient ratings are confusing (ex. natural fragrance has like 100 diff. names); Look out for reviews of products before buying (just because it's a '0' on the scale doesn't mean it's the best option out there😅).

    Don't bother with this if you live outside of the USA. I live in the UK & tried to use it repeatedly. It didn't recognise any of the products I tried to scan/ stated they weren't in the database (this included products from The Body Shop. Not exactly a niche, unheard of brand). When I tried to manually enter each product (a complete ball ache) the app repeatedly crashed. Talks a lot about the FDA/ how the EU regs are better, so I suspect it would work in the US.

  • No data on common brands Feb 17, 2020

    By pearsandclementines
    I got this app for the purposes of learning more about the products I apply every day and potentially turning over my makeup bag to include less harmful products. Immediately after downloading I started searching products in my makeup bag to learn more about the ingredients. There was no data on my bronzer, foundation or primer by Fenty Beauty, my Too Faced lip gloss, my mascara, or Glossier brow gel. Admittedly, I don’t race to get the newest release of lip kits or products but I also know that I’m not working with out-of-date or obscure makeup. I’m surprised that there would be no information on my products from the three major brands I listed above. I did get prompted to upload info and submit my products to the app’s database but I could not get a clear picture of my product even after 5 retakes. I don’t have this issue when using my iPhone camera normally so I can only assume it was an issue of the app. I don’t want to completely disregard what this app has to offer. The ability to look further into a certain ingredient with one click and get and overview of health effects and usage with a list of sources is so convenient and the concept I came for. I’m just disappointed that for have an average makeup bag with products from big names that I couldn’t find what I was looking for. For now I’ll just do my own research via Google.

  • The app is biased and not giving full info Feb 20, 2019

    By Gabsteryyy15
    A friend referred this app to me as an expecting mother. I got the app and started scanning and was appalled at what the app thought was dangerous. I did my research on some ingredients, carcinogens, health problems and whatnot. The app is very biased towards organic product. If it’s not organic, they will label is 8-10 and call it very dangerous. One of my products is labeled a Group 2B by the national Cancer society- there is a possibility of it having harmful effects towards humans but the studies were inconclusive since it was tested on animals and not humans. But the app said it was a 9- very dangerous. It’s good to know what is in your products, but the app doesn’t tell you how much exposure to a product you’d have to endure before seeing effects of the bad ingredients. For example, *possible* carcinogens are found in Johnson and Johnson baby body soap. But to see effects of those possible carcinogens, a baby would have to be exposed to thousands and thousands of gallons. And even then, it is only a slight possibility (less than .0001%) that the child would get cancer. The information the app provides is misleading and it’s in favor of organic products. I think the app producers get paid to rate those products as “heathy products.”

  • Love this App! Everyone NEEDS this! Sep 9, 2019

    By Agilbster
    Love this app, it really has brought me so much awareness to all the chemicals & horrible ingredients in all my products! I used to think if i need to see the ingredients, just check the back, but companies can be so shady & misleading, making you think their products are all natural, eco-friendly, organic, etc. & then you scan the barcode & the product is an 8-10! I’ve been in the process of transitioning all my products over to healthier/eco-friendly products with the help of this app, but it can be very challenging because many of the healthier products either are so expensive or don’t work so needless to say i have been through many product fails & lots of money, but still trying! My only 2 constructive criticisms & the reason why i only gave 4 stars is because sooo many products that I scan aren’t in the system, which I understand because there are so many products out there. I also really wish there was a way to sort/filter the products by cost or an average cost (because i realize different retailers sell for different prices). It would save so much time trying to search for healthier options to potentially buy. Overall Love!

  • Very Useful App Feb 27, 2020

    By kkosano
    This app allows you to check what chemicals are in your products and determines wether or not they are harmful. I didn’t realize how “dirty” (products that contain harmful chemicals that can be possible carcinogens) the items I owned were until I checked this app. It’s a great tool to use to be more conscious about what products to buy. You can search specific products using keywords or brand names to check their “dirty” score. While there are a variety of products, not everything is in the system. You can upload product information if it is missing which will be reviewed and later added to the system. I knocked one star down because the app seems a little difficult to navigate, especially when looking for a specific product. Sometimes typing keywords is not enough to locate the item which can be a little frustrating. Depending on the product, there can multiple submissions with different scores that could be confusing. Other than that this is a great tool to have; I use it for all my products and am working towards cleaner products. I would definitely recommend this app for the conscious shopper.

  • Most extensive app in clarifying cosmetic ingredients lists Nov 20, 2019

    By qdbass
    They don’t just slap a grade on said item, they clarify the entire ingredient list. They give grades to both the product itself as well as each ingredient within the product. The best grade a product can have is a “0”, meaning it has extremely low risk ingredients- if any (I believe it is considered in the “green category” with a grade between 0-3; “yellow category” is 4-7; and “red category” is graded 8+). When you click on an item, it shows the list of ingredients, sorted by most toxic to least. You can click on any one of them to see the nitty gritty details, including scientific name (or other names it may be disguised as), usage and health impacts. There are other perks that are probably to be expected, like saving products to your “bathroom shelf” list or “dirty products” (I have yet to use all of those features yet). These guys have all my support but I deducted one star for difficulty finding many items I’ve tried searching for, as in they are not yet in their database. I wish there was a way to suggest products or brands for them to add, otherwise a really great app for cleaner living :)

  • At the least it makes you think Jan 23, 2019

    By MMBrady_Theo
    I downloaded this app several years ago. I went on a scanning frenzy. It was both alarming & terrifying to read all the suspect ingredients that were in items I had assumed were for the most part safe, particularly skin care. One expects chemicals in cleaning products, but not your lotion or toothpaste or even laundry detergent. It also made me think about where all these chemicals end up, that is in our water supply & soil, basically they are assimilated into our environment one way or another. That is the real benefit of this app, it makes you stop & think. I have found that some of the rating is misleading & not fully accurate like they are trying to scare people. I do not like the persistent level that they push products on users. It seems to have increased significantly since I first downloaded the app. Also I had a ton of products scanned & submitted that were not in the system & they are all gone now. That is extremely frustrating to me. It takes time to input products. I check back occasionally to see if they have been rated & to find that they are all just gone was pretty crappy.

  • This app is super helpful..... BUT Jun 23, 2020

    By Candycrrushqueen9362589492
    I really do like this app, it’s a simple way to look at the ingredients and quick. What I don’t like is that if you have a bottle of shampoo with all 0-3 rating ingredients and one single ingredient is bad (8) that shouldn’t make the overall rating an 8. If the last ingredient (since this is the least amount) in the bottle is that bad rating then it should be weighted so that the overall rating isn’t just ruined because of an ingredient that’s barely in the product. There should be a better system here. Maybe even just a mean of all the numbers to have the rating. I don’t like the way the app does it at all. I’m not gonna be worried about 1 ingredient especially if it’s last in the list. Other than this I like how every ingredient is given a different number and color, it makes it easy to check out what’s in my product instead of trying to remember every bad ingredient in the store while reading the bottle. Finding the product is a little crazy if it’s not a popular one, and sometimes it’s not even on the app.

  • Needs to be updated. Very glitchy. Dec 3, 2018

    By Nsb4
    Loved this app at first. It seems they spend more time pushing the products they are sponsored by instead of cleaning up listed products and repairing the glitches. That’s fine if they are reliable products that work. Most seem like they do. I have found many products with conflicting ratings! Also products given a score with no ingredient information. They should not be listed if no reason for the score given. So many products I’ve searched for are not in the list. I submitted popular products many months ago to be reviewed and still are not shown. But I do understand the data base is constantly being updated. The comment review feature is a bust for me now. I am unable to read comments on the products. Not to mention it’s very glitchy and stops working every time I open it! I gave it 3 stars because this app has a great foundation to work with and will be great once these major kinks are worked out.

  • Ehhhh..... Jul 6, 2020

    By 2222Emmy1115
    Yes, it does tell you what is good for your skin accurately...just if it has that product in its library. I’ve scanned all of my products and just a small percent of them were able to be scanned and rated by the library of items in the app. The only thing this app is good for is telling you how bad your current products are, and then if you’d have enough money to buy them, you could buy much more expensive products that are much “cleaner” for your skin. I don’t know how I feel about this app, but I’m not going to waste my money when I already have all of the products I need. Originally I thought this app was going to tell me how good ALL of my products were and then give me deals based on my collection. I think this app is only useful if you want to buy better and cleaner products for your skin than what you already have, but I know I won’t be getting this app again.

    i feel like i’m entering in more products in their database then i’ve looked at on the app. i also feel they label incorrectly. in one hair product, i found that they labeled the product bad because of a certain thing that was bad in makeup, but it was certified to be safe in hair. so for me that bad rating on the ingredient didn’t apply to the product, and it told me this when i clicked on the bad ingredient on the list. so you really have to look to make sure the rating is even correct, but hey i guess a bad ingredient is a bad ingredient. i have curly hair, so my products are almost all she’s butter moisture and Aussie. all Aussie products i looked up/scanned aren’t even on the website. i also use a sulfate & paraben free shampoo/conditioner from Aveeno, that wasn’t there either. like i said before i enter in more in the database then i’ve found. so personally i find this a little useless.

  • A blessing and a curse Jul 30, 2018

    By Emjhartl520
    A friend posted online about this app several months ago and immediately I was obsessed. I liked how products were broken down and each ingredient rated and explained; it seemed very thorough. Every time I shopped online or went to a store for a new product, I opened the app and searched and scanned, checking to see if what I wanted was “approved.” Here’s the catch: I fully believe that they totally ignore user-uploaded products. Really basic and popular things I use, from major brands, have not been added for months now. Brands that are up-and-coming in the natural/non-toxic beauty world are not even listed. The makers of this app are clearly focusing on promoting products from sponsor companies and other great products get left in the dust. It is useful but only to a certain extent. A good starting point for someone looking to clean up their beauty routine but shouldn’t be considered a thorough resource. Also, it glitches and refuses to load about a third of the time for no apparent reason.

  • Great concept but has issues that make it ineffective Dec 10, 2018

    By ogbcd
    Pros: helpful to read why certain ingredients have negative ratings and their effects with scientific-study backed claims and sources. Cons: missing a majority of the brands and products I use (no Oribe products at all, Olaplex shampoo/conditioner, very few Drunken Elephant products, no Korean/Asian skincare brands doing the most innovative and therefore health-curious products (Cosrx, Bio-Essence), and very few non-drugstore or direct-to-consumer brands (little to no The Ordinary, no Playa hair, or Margiela products). Almost all products I use are bought from Sephora, directly from the brand or Asian/k-beauty stores and don’t have barcodes or aren’t featured in Think Dirty’s libraries so it renders the app fairly useless for a consumer like me. Not sure where the majority of their users shop or live but most products aren’t recognizable to a New York/US-based consumer who geeks out on beauty products and has countless ones she wants to know the real scoop on.

  • Very misleading now pushing notices more than daily Mar 20, 2018

    By chipotlite
    I downloaded this app a few years ago after reading about it on a favorite bloggers site. She was very impressed. I checked a few things I use and a few things the blogger was throwing out. I have a BS, MS, and doctorate degree in the sciences. My masters is in Environmental Sciences. I have always worked in the biological sciences. I found the app information and scoring quite alarmist. Here’s an example. Selsun Blue is listed as toxic. The reason because it has Selenium. Selenium can be toxic. But it is also an essential mineral for animals. So just stating it is toxic is silly. A short exposure to selenium in your shampoo should not be harmful. In fact tinea versicolor a fungal infection of the skin can be treated by applying Selsun Blue to your skin and waiting 20 minutes before showering. So the suggestion that simple use of Selsun Blue as a dandruff shampoo is dangerous because it includes selenium is at least misleading. I haven’t used the app in a few years. What lead me to comment today is the fact that this app has started sending me notices. It is pushing products.
