"What Can a Curl Test Really Tell You About Your Hair?"
Hey everyone! So I’ve been hearing a lot about the curl test lately—y’know, where you pluck a strand, drop it in water, and see if it floats or sinks to determine porosity.
But like... how accurate is it really? I tried it and got mixed results. One strand floated, another sank halfway, and I’m just confused lol.
Does the curl test actually give useful info, or is it just a guessing game? Some say it’s great for figuring out moisture needs, but others swear it’s totally unreliable.
What’s your take? Have you tried the curl test? Did it match up with how your hair *actually* behaves? Or is there a better way to figure this stuff out?
Kinda curious if I’m overthinking it or if it’s legit. Thanks!
Honestly, the curl test is kinda hit or miss for me. I’ve done it a few times and got different results each time, so I don’t totally rely on it.
But I *have* found that my hair acts more low-porosity, even when the test says otherwise. Maybe it’s better to just pay attention to how your hair reacts to products? Like, if it takes forever to dry or repels moisture, that’s a bigger clue than the curl test.
If you want something more reliable, try the strand test where you stretch a wet hair to see elasticity. Or check out NaturallyCurly’s porosity quiz—it’s way more detailed!
The curl test is fun but not super scientific lol. Hair strands can vary so much, even on the same head!
I’ve heard that things like product buildup or damage can mess with the results too. Like, if you’ve got a ton of conditioner on your hair, of course it might float even if it’s high-porosity.
Maybe try clarifying first and then doing the test? But tbh, I just go by how my hair feels. If it’s thirsty, I deep condition. If it’s limp, I clarify. The curl test is just one piece of the puzzle.
I swear by the curl test! It helped me realize my hair was high-porosity, which explained why it was always so dry.
But yeah, you gotta do it right. Use clean hair, no products, and test a few strands from different spots. If some float and some sink, you might have mixed porosity—which is totally a thing!
For a deeper dive, check out CurlScan’s guide on hair porosity. They break it down way better than I can.
The curl test is like a party trick—cool in theory but not always useful.
I’ve had strands float one day and sink the next, so I stopped stressing about it. Instead, I focus on how my hair behaves with products. Does it soak up leave-in like a sponge? Probably high-porosity. Does it take forever to dry? Low-porosity.
If you want a more consistent method, try the spray bottle test. Spritz water on clean hair and see how fast it absorbs. Way easier than the curl test, imo.
I think the curl test is overhyped. Hair is too complex for a simple float/sink test to tell you everything.
Like, my hair floats sometimes but still gets frizzy and dry—which doesn’t match the “low-porosity” label. Maybe it’s damaged? Maybe it’s the weather? Who knows.
Instead of obsessing over the curl test, I just experiment with products until I find what works. The Curl Ninja blog has a great post on DIY hair diagnostics if you wanna go deeper.
Wow, thanks for all the insights! I had no idea mixed porosity was even a thing—that might explain my weird curl test results.
I’ll definitely try the spray bottle test and check out CurlScan’s guide. And yeah, maybe I’ve been overthinking it lol.
Quick follow-up: has anyone tried the strand stretch test? Does it give clearer results than the curl test? Just curious before I start yanking hairs out haha.
The curl test is a decent starting point, but it’s not the end-all.
I’ve found that my hair reacts differently based on the season—like, it’s more porous in summer because of humidity. So the test might not always be accurate.
If you’re really curious, try the “slip test” too. Rub a strand between your fingers—if it feels rough, it’s probably high-porosity. Smooth? Low-porosity.
Also, the Hair Porosity Handbook on YouTube has some great tips beyond the curl test.
