HairKeeper is a lifestyle app that promises to make it easier for you to check the ingredients of your hair cosmetics in a few seconds. The app allows you to scan the list of ingredients of a shampoo, balsam or mask using your phone's camera and covers the type of detergent, presence of silicones, drying alcohol, potential allergens, as well as emollients, proteins, and humectants. You can read more about what these ingredients mean by clicking "Info" in the app.

One of the best things about HairKeeper is that it doesn't require an internet connection, making it very helpful when you're shopping abroad or don't want to use up your precious roaming data. The app is also available in four languages: Russian, Polish, Spanish, and English.

However, the scan functionality is limited in the free version with only 7 scans available. After that, a one-time purchase is required to unlock unlimited scans. It's worth noting that the app developer can be reached at for suggestions and complaints.
