Review: Great Product & Accurate - I am Black and I have recently went natural with my hair. I tested all rhe products that I use on my hair from the shampoos & conditioners to the creams, oils & gels (commercial and homemade). I found that these PH strips were very accurate. It read the PH levels consistently and there were variation in the different products. Since I am newly natural I am making sure the PH balance are correct because my hair is in a a newly fragile stage and these strips worked perfectly. Easy to use and read with the chart. I was able to differiate the products with the most acidity and save them for later in my hair journey when my hair is stronger. Since there were 100 strips I am sure I may have to repurchase again later this year to monitor any new and ongoing products for the future. Great product!
Review: So far so good - As an Esthetics Instructor, I was looking for inexpensive 0-14 pH testing strips to use in the classroom. At 12 cents a strip, this was a great deal. The value was even better when I began to use them. The pH of the products we use on our skin is very important. Sometimes we want to raise or lower the pH, but we also want to make sure we are following that with the proper product to then neutralize the skins pH. Using these strips makes for a great visual aid and makes teaching (for me, and understanding for them) so much more effective. I have used them on many products I already knew the pH of, and every time they have been accurate. The no-bleed factor is great too, as I feel comfortable dipping the strips right into my product. So far, this product hasn't let me down. I will definitely be sticking with this product when it's time to reorder.

## Questions & Answers

**Q: Will this work to test hair products re shampoos, conditioners, etc.**
A: maybe and maybe not.... i would just send a quick email to the product manufacturer & ask them 2 questions:  1- what is the pH of their product(s)? and 2- will these photo strips work on your product(s)??   Overall, i would say that if the product in question is a water based product, than the strips will be close but the other chemicals may mask or interfered with the true results....

**Q: the product claims '0-14' ph but I only see seven numbers [from the picture] to compare the test strip. Can someone clarify?**
A: The other seven numbers are in the back side of the box that you can not see in the picture. It is correct from 0 to 14 pH.

**Q: Where are these strips made? are they made in usa? thank you.**
A: These test strips are made in Germany.

**Q: there are no instructions. how do I use them?**
A: * Immerse the test strip briefly (for approx. 1 sec) in the sample solution.* Subsequently, compare against the pH color chart supplied with the kit.* Read off the pH.

### ⭐⭐⭐ Only half functional
*by K***P on May 18, 2025*

The app that’s intended to help you interpret the results doesn’t work, so you can really only know pH to the nearest whole number
