Calcium Gel Nail Builder - 13.5mL Base Coat Nail Polish | Clear Nail Polish for Nail Care & Nail Strengthener for Thin Nails and Growth | Fast Dry Nail Hardener & Nail Growth Treatment, 1 Unit

Bought for boyfriend who is a habitual nail biter. He'd subconsciously bite until his nail and skin would hurt and bleed. After quickly realizing that his life long habit was not gonna go away on its own I figured I'd give this a try. It has zero gloss to it and looks like a traditional nail polish bottle. Reluctantly he let me "paint" his nails and after day 1 he stopped the biting. The taste is baaaaad, not exaggerating even in the slightest, its one of the worst things I've tasted. WARNING: when applying to someone else, either use a paper towel or gloves because somehow the gloss leaks and gets on your hand/finger and even after washing your hands immediately after, you taste this sucker for a good hour. The taste completely deterred him from biting, although he did forget once and out of habit put his finger on his lip.... that was enough to not go any further. Be careful when eating finger foods, you'll definitely ruin your meal after 1 lick of your fingers lol. He did mention that after 3 days or so he noticed the polish disappearing and surprisingly asked me to reapply it. Its been 2 weeks now and OMG his hands look amazing. After years of his family trying to get him to stop, this little bad boy did the trick. So happy!

Well I did some research before I bought this. My 7 yr old daughter is a nail biter and cuticle biter. Terrible! I put this on at bed time one night and the next day when she stuck her fingers in her mouth she was so confused and grossed out. Product works! All I have to do now is threaten to put it on her and she will stop. Thanks for this gross but good product!

Helps polish last longer! Good quality! Only thing is it takes a couple minutes to dry.

This nail polish has helped my brittle nails become strong and grow beautifully. I kid you not I apply it during the night by the next day my nails are growing and stronger. My nails tend to get brittle and break often so this helped soooo much.

I’ve been trying to help my five year old stop biting his nails. I was admittedly a bit too excited for this product, I was hoping to finally find an end to the constant battle over nail biting. I was also secretly a little bit eager to see that first accidental taste. Don’t worry, I ended up getting my just deserts. After applying to my child’s nails, I was sitting in wait, eyes watching closely, when suddenly there was this awful bitter, ear waxy flavor in my mouth. Yep, I got the first taste and boy was it awful. It took a few washes to remove it. So wear gloves when applying to someone else, I did wash my hands throughly after applying and it still lingered, strongly. Anyway, my child got a taste too and at first was not thrilled by it, but quickly and unfortunately got used to it. I tried reapplying but it was no use. So no it did not work for us, but it lives up to its promise of a disgusting reminder not to bite fingers as long as you have normal tastebuds. It is also clear without any shine, nails look natural and unpainted if you’re worried about that, don’t, no one will ever know your nails have paint on them, unless you feed them with your fingers. Don’t do that, or feed yourself, with fingers, you will regret it. Click the helpful button if this review was helpful to you.

Este fue el producto que estaba buscando!!! Mis uñas se empezaron a hacer débiles, no crecían rápido, se rompían muy fácilmente y se quebraba en capas. Probé muchos tipos de barnices qué decían eran para reparar todos esos problemas de las uñas y nada me había funcionado hasta que probé este barniz y logró hacer lo que ninguno. Por fin mis uñas lograron crecer, no se me rompieron y ya no se me se tronaban por capas. Funcionó tan bien que hasta mi hermana al verme pensó que me había puesto uñas postizas, así de bonitas crecieron. Sinceramente no pensé que fuera a funcionar como los muchos que había probado, así que no tome foto de antes y después, lo hubiera hecho de haber sabido que mis uñas se arreglarían. PRODUCTO 100% RECOMENDADO a mi me Funcionó desde la primera vez.

We purchased this product for our 4-year-old son because he was constantly chewing on his fingertips. We put it on him and he promptly put his fingers in his mouth and complained about the awful taste. So far, so good. A few minutes later he began throwing up - a lot. He seemed better an hour later, but I would definitely not use this product again.

I’m really pleased with this purchase! I’ve been a nail biter for 22 years and this has finally encouraged me to stop. Apply once every ~3 days, either on bare nails or on polish. It doesn’t have a shine. Be careful the first 12 or so hours, because the taste WILL transfer to anything your nails touch. It‘s nasty enough to deter you from putting fingers anywhere near your mouth, but it’s not so nasty as to make you ill if it happens. If I happen to get through the entire bottle (which is doubtful, I’ve hardly made a dent in it), I would be happy to purchase again.
