Helped my damaged nails become strong again!
I naturally have thin nails, so after a couple too many nail fills, my nails were crying for help. They were thinning even worse then before, and they had no strength. They were ripping off and chipping at the ends, and i knew I needed to do something to help speed up the healing process…I’ve been using this 3 times a day, sometimes not when I remember. And my nails are growing fast, and feeling strong again! All of the flaky areas are back to normal! When you use it, it feels like you’re nails are taking a deep breath. It’s feels like a cooling sensation that is soaking into your nail! I love this so much! I will be using it from here on out in between nail fills!!

Must have!
Ones might think it’s too costly at the beginning. But I have been repurchasing this product and recommending to all my friends. The nourishing experience is real and quick. Whenever now I have a coming-up event to attend, I will rely on this probiotic nail product. It provides me lengthy and healthy nails within couple days.

Really nice mask
I love that this is a wash off formula so it doesn’t interfere with your manicure. I’ve used it for about a week now and it is very easy to use and I think is really helping my nails

So Good for Dry, Brittle Nails
I’m almost through my first bottle of this stuff and I really love it. My nails are super dry and brittle, so they break very easily instead of bending with pressure. This stuff is like a lotion for your nails, it’s so moisturizing!It doesn’t dry down like a polish, so it’s more like a cuticle oil in application. It has a brush like a polish though, so I just paint it on thick after trimming, filing, and reducing cracks. I let it sit for as long as I can refrain from touching anything so it can really soak in. Then I rub it into my nails and they instantly look so much better without the visible cracks. It does wash off when you wash your hands, just like a lotion, so I’ll reapply multiple times in the day. I like to use it for a day or two between polishes to let my nails really breath and relax. They’ve improved so much over the last week.

Meh
I got the Nail Probiotic Instant Boost. This is a great product, worth the extra couple of bucks. I thought it was tinted nail polish and wasn’t expecting much but I received it and used it right away and was pleasantly surprised—it’s like a nail moisturizer that creates a protective sheen (and smells great, and is vegan and cruelty free). It’s a smaller bottle but it’s not a mini bottle, I imagine it will last me at least 6 months (maybe longer for someone who DOESN’T have chronically dry skin and splitting / peeling nails). I use it every day and have not had allergy or irritation issues. Apply it like nail polish and give it about 10 minutes and you’re good to go (side note I wouldn’t recommend it as a base coat for nail polish).EDIT: After some use I noticed this product isn’t what is / was keeping my nails healthy. It’s just a sticky coating that never dries and sort of hangs out on your nails until it gets wiped off. It also got rancid after a month and went from having a pleasant scent to smelling like a bottle of old cheese. Save your money.

Healthy nails after just one application
This is great on your damaged nails. I ordered this last night and received it this afternoon. Following directions, with the exception of washing my hands-as I left the product on, I applied the probiotic only once, waited 10 minutes and then massaged my nails and walla… my nails look great after over 4 years of trying to get them healthy. I love it. Get it – do not hesitate. Don’t think it is expensive – you were paying much more going to the salon every two weeks.

Mirin a bottle
My nails were like soft crab shells, peeling and soft.This stuff is amazing. After one treatment, I could tell the difference.This will be a permanent part of my nail routine!

I can FEEL the difference!
I didn’t even know that this was a thing and I am SO happy I found it! I have always had thin, brittle, easy to break nails so I keep them covered with powder dip so they won’t break all the time. First of all this stuff smells amazing which I totally did not expect! The consistency is thicker than polish but glides on like polish so it goes a long way. After letting it sit for 10 minutes I washed my hands and nails and could tell that they were more moisturized just by looking at them. Touching them they feel so soft but I swear it was like they took a deep breath and relaxed in my nail bed. They just felt better. This stuff is incredible!! I’m subscribing so I never run out!

I’m not sure what to say about this product. It feels like a mask for the nails, a medium-strength conditioner after removing gel or polish. But it didn’t work as expected. The nails looked a little more hydrated after the application, but it didn’t make a huge difference. Due to the high price point and the results, I would not recommend it.
