These are the masks I’ve tried that have a pH level below 6.0 (in alphabetical order by brand). I’ve also included a link to my review, where applicable.

Please note that I use pH strips and they aren’t a perfect science so the pH levels noted below are estimates only and let us know if a product is on the acidic side (or not). There is also some variation between batches of products and a manufacturer may have made changes to their formula since I tested.

The majority of the products listed below are also silicone-free and sulfate-free.

If I have written a review, a link to it is below. My reviews also include an ingredients list although the ingredients may be inaccurate (depending on the original source/translation) or have changed after a review was posted.
