Hard, strong polish finish
3 years ago
No complaints stand out when I’ve tried this brand. Gives a nice hard finish and can’t beat the price compared to salons.

Classic

This stuff is some classic OG style strengthener from Sally H. We go waaay back lol. It's a suffice product, but there are alot more cleaner ingredient nail strengtheners out there that I prefer now. But if your in a pinch & low on funds this will work

Really like this product. It does really well if you have your hands in water a lot, keep your nails hard and helps with not breaking them.

I always use a good clear coat to keep my nails healthy. Mine are usually thin and break kind of easy. So i use this option when i want to give them a break on color.

Does what it should

It’s a nice clear coat, not particularly expensive or cheap and is in a pretty bottle. I would prefer if it dried faster but otherwise I think it’s great.

It was available at my local Walmart when I was in need of a nail strengthener during the pandemic and my salon was closed. It got me thru but not something I would use routinely

When taking a break from acrylic overlay, I always turn to this product. Diamond strength by Sally Hansen leaves my nails looking healthy and shiny while building them up and help reverse the damage of acrylic overlay.

good for a base

I use it a lot when I take off acrylic nails. And I use it as a base for when I do my color street nails and it helps a lot. Less breakage with continued use!

Makes a good top coat, adding some extra strength to your nail while also protecting your polish. Even though it should go directly on the nail.

Helped rejuvenate my nails
3 years ago
I love to wear nail polish all the time. I find over time my nails become yellow and start to peel. I will take a break and use only this product. It helps to repair and heal my nails so that they are strong and healthy again. I would recommend this product to others. It smells strong so use it in an open area.

Lasts not as long as expected but might be just me
3 years ago
Brush is okay, color options are there but this didn't last long for me. It's difficult to apply with a small brush and the paint separates when you don't use it often so you gotta shake it well.

I like it ok it I don’t like to sit for 30 minutes to let it dry. I haven’t really tried anything but this brand maybe I should try other brands how ever it is very pretty when it drys. I have very brittle nails due to Hypothyroidism and I have been on meds for 6 years and no difference trust me if you don’t have it but I ok someone that does trust me that if they tell you they are tired and don’t feel good just be there for them I don’t have any one and I wouldn’t wish it on anyone with loosing my hair eyebrows and eyelashes. It’s terrible

Pretty good for flimsy nails
3 years ago
My nails are flimsy, they will peel and split and invariably break. When I was growing them, this was a must as otherwise, they are just short and not nice looking. Also good as a top coat to protect your manicure!

This does work

I struggle with brittle nails that break and peel. I also have a bad habit of biting my nails. This helped me not bite my nails and I saw an improvement with the breaking and peeling.

Pretty Good Shine
3 years ago
Goes on smooth & lasts. This definitely hardened my nails& the shine lasted for about a week before I needed to re-coat them. I manicure my nails twice a month & each week I do a Lil upkeep in between. This is good for that. I do acrylic & gel nails & my gel clients like it but the finish isn't the same for acrylics honestly.

This is a good top coat. Makes nails shine and durable. Great to use on natural or artificial nails and I had no problems with chipping at all.

No more flaking

My nails were starting to peel and become more brittle as the seasons changed so I picked up a bottle of the Sally Hansen Diamond Strength at CVS. After using it for a few weeks, my nails were noticeably stronger and did not peel anymore. I would recommend this!

This worked great as a clear coat. It stayed on and gave a nice shine. I can’t say I necessarily noticed that it strengthened my nails.
