There are 2 brands I use. I often buy them online because I can get the brand I want at a good price.

One is Hyrdion (also labeled as pHydrion). Make sure to look for test strips or paper with a range from pH 0-13. Don't get pH test strips made for urine and saliva testing, the range is not great enough.

A brand that reads very clearly is ColorpHast with a range of 0-14. There are differently-colored pads on each strip that you match up to a scale on the case. This assures a better match than only one color. That's good for use with indoor lighting or in products with a slight color. While they may seem pricey up front, one package should last a long time unless you get very interested in testing pH and it is better to test pH now than to deal with damaged hair later!©Science-y Hair Blog 2013

Important Note: When you test pH, test room-temperature liquids. Testing hot liquids is likely to give you the wrong reading.
