Reddit reviews Micro Essential Lab 3110M18EA 325 Hydrion Short Range pH Test Paper Dispenser, 3.0-5.5 pH

FWIW, those strips are terrible for measuring exact pH levels. I wrote a whole post on why I won't use these strips to test cleanser pHs in a narrow range. Using the large range pH strips is like using a sledgehammer to make a small hole in your wall. Sure, it makes a hole in the general area you want, but it sure as hell isn't going to be exact. The post goes into some detail about how pH indicator dyes work. I actually recommend these strips instead, if you are interested in the pH of things between 3-5.5 pH. I've used those strips to test out the pH of Innisfree's Bija Anti-Trouble Cleanser, CosRX's Good Morning Gel Cleanser, and CosRX's BHA blackhead toner, and the results were much more accurate and easy to read than the 0-14 pH strip range.

TL;DR - the accuracy of your pH strips is the more likely culprit. Use pH strips with the appropriate range for the items you are measuring. Big range pH strips are good for telling you if you have an acid or base, not good at fine-tuned pH level indicators in the 0.5 pH range.

Might be bacterial vaginosis, it can be subtle for some women. This might help you narrow it down in the meantime.

First part serious. Second part funny.

If the pH of the shampoo isn't advertised, you could simply test it yourself. Supposedly pH balanced shampoo (different from pH neutral) is supposed to be like 4.5? So you'd need a test kit that would be able to distinguish 3.5 from 4.0 from 4.5 etc.

Edit: If it was me and I wanted to find out the exact pH of my shampoo, this is what I'd buy.

pH testing isn't too expensive as far as brewing equipment goes.

Strips -get the ones for the pH range that you are interested in, in this case the acidic range. The pH strips that range from 1 to 14 are a lot harder to read accurately.

Alternatively you could get a meter (my recommendation if you can pick one up for less than $20). While not lab grade, even the cheap ones are good enough for our purposes.

I honestly don’t think they check the pH standard. They do sell over the counter pH test kits in the pharmacy (or you can order pH test strips by the roll on amazon for wayyyy cheaper you’ll want this one Micro Essential Lab 3110M18EA 325 Hydrion Short Range pH Test Paper Dispenser, 3.0-5.5 pH https://www.amazon.com/dp/B00LY1KIWY/ref=cm_sw_r_cp_api_vx47BbNRK6A0F). Normal vaginal pH is around 3.8-4.5 so if you’re outside that range (usually higher than 4.5) it’s pretty indicative that you have BV.
