Ratings and Reviews
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!
I went through my cosmetics and hair products and ended up tossing a large bag full of products that had a bad rating due to the ingredients by checking them out on this app. I began to buy items with a 0 or 1 rating for the sake of my skin and hair. By using this app to look up a product, I no longer have to research whether or not a product ingredient is good or bad for me which saves me a lot of time.
There was one brand of hair products that I bought including shampoo, conditioner, dry shampoo, dry conditioner, blowout spray, and shine cream. Eventually, I began losing my hair, lots and lots of hair. I told my hair dresser that I thought I was allergic to that brand. She didn’t think so and sold me more of the same. What a dumby, I actually bought more. When I got this app, I looked up that product and found that it was given an 8 rating. I threw it all out. I’m hoping my hair grows back in but to make sure of it, I will look up any shampoo for a 0-1 rating from now on. I am very grateful this app exists and for all the people who work hard providing this information.
Better search options
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....
