Liaison UltraGrow Nail Serum for Growth and Strength with Keratin Complex, Olive Oil & Vitamin E | Dermatologist-Tested to Support Weak, Brittle, Splitting Nails

It really works! I’ve bit my nails my entire life and they’ve gotten so soft over the years. Tried all kinds of nail polishes that claim to harden nails but it never worked. This one really does! And it helps growth too. I don’t even want to bite my nails anymore. I saw improvements in the first couple of days!

The email does not work. The phone is unanswered. The directions are not complete. It does not say how often to apply. It is too much money for no support. Back It goes.

This product works. I have bought all kinds of products, and nothing worked. I saw an ad for liaison, and I ordered it not really expecting the results I got. My nails are growing stronger and they are not splitting. I have just ordered my second vial.’

My fingernails have been paper-thin ever since I was a child. I have no idea why; my toenails are normal, I take calcium, biotin, hair/skin/nails vitamins, even prenatal vitamins despite being postmenopausal because I heard that they're helpful for hair and nails. And my nails continue to grown about a quarter-inch and then collapse and tear if they're exposed to, oh, say, a moderately stiff wind. I have a couple of mystery/chronic illnesses, so I've had all the bloodwork done that you can possibly imagine, and they tell me everything is perfectly normal, even though it obviously isn't. So ANYWAY, the bottom line is, if this serum can get MY nails to grow stronger/thicker, it can probably help anyone's.I'm going to be doing as close to a "clinical trial" as I can manage, with weekly photographs and measurements (and eventually measuring the nail thickness with a micrometer if I can get my hands on one!), applying the serum to one hand and not the other for a month, and then switching, so I can compare and get (I hope) an accurate and reliable assessment of the results. I will update this review with the findings!For now, I can say the serum came in a well-sealed package with an expiration date of November 2027 (purchased in May 2025). It has a decidedly unpleasant smell, but the smell fades quickly as the product dries (it's not very oily or greasy and dries/evaporates almost completely in about 30 seconds). I do have a tendency to... not really BITE my nails, but sort of use my teeth to clean under them, if that makes sense? and the taste of the product lingered a bit - enough to be unpleasant and remind me to keep my fingers out of my mouth, but not enough to send me racing for the mouthwash or anything. There was no burning, tingling, or other unpleasant/unusual sensation to the nail or cuticle, even when I got some on a hangnail.Updates to follow in a few weeks, and more on a (hopefully) regular basis!Full item name: Liaison UltraGrow Nail Serum for Growth and Strength with Keratin Complex, Olive Oil & Vitamin E | Dermatologist-Tested to Support Weak, Brittle, Splitting Nails

I have been using it for about 3 weeks and haven’t noticed any major improvement. I won’t buy it again.

This does really work. My nails were so thin they almost didn’t exist. After a couple of weeks my nails did thicken. They’re still on the thin side but my nails literally were so very thin, thinner than any other persons nails that I’ve seen. I do recommend this product.

First ingredient is water. Water is the worst thing for fingernails. It makes them swell and split.

Seems to be working
