Sally Hansen "Diamond Strength"
OMG, FYI, FWIW...
I still like this stuff. My last run lasted almost 3 weeks with a lot of re-coating and touchups. It finally gave up by peeling/lifting. I got most of the third week by catching the lifting and "gluing" it back down with more nail polish. It worked.
But, my bottle was getting low. Did some more research. Learned that this stuff is basically nitrocellulose lacquer (folks in the Uke Building forum know what I'm talking about). That explains a lot of why it does what it does. Multiple layers fuse together nicely, and it's easy to smooth imperfections and polish with a glass nail file. Neat!
I found that Sally makes another polish that's VERY similar to this one. Almost identical. But, instead of "diamond powder" and "titanium", it uses polyester as its strengthening additive. Okay, I don't mind that. I always thought the "diamond" and "titanium" stuff was just marketing, anyway. And this other one (Sally Hansen Double Duty base and top coat) is slightly cheaper. So, I gave it a shot.
It's mostly the same. Goes on the same. Dries as quickly. Re-coats the same. Generally behaves the same in every way. BUT... it's obviously softer. It develops scratches and dings more readily than the Diamond stuff. It also FEELS softer. Not quite "sticky", but... well, "plasticky". The Diamond stuff always felt hard.
I still wanted to give it a fair shake, so I've been living with it for the past week. It's totally NOT protecting the tips of my nails! Those tips flex a little bit, and this stuff just starts flaking away. Nowhere near as strong and durable as Diamond Strength.
It IS holding up reasonably well on my strumming thumb. But, that one, I took care to coat all around the tip of the nail, and UNDER the nail. And applied three coats from the start. Added a couple more from there. It's still starting to lose a corner already. Something the Diamond Strength would not do using similar application for about 2 weeks.
So... there's something to the Diamond Strength. It really is significantly stronger than even the same BRAND of product with every other ingredient being exactly the same.
Looks like I'll be stripping my nails again tomorrow. Back to the good stuff!
