ella+mila "No More Biting" Nail Polish - Bitter Taste Nail Biting Treatment for Kids & Adults - Stop Thumb Sucking Deterrent - Finger Biter Prevention (0.45 fl oz)

The bitterness of this polish is intense and immediate. It is specifically designed to deter both nail biting and thumb sucking, and it works exactly as intended. The taste is very sharp and lingers, which is the perfect reminder for anyone who bites their nails subconsciously." Clean Ingredients (17-Free) "One of the best things about Ella + Mila is that it's a '17-Free' vegan formula. It’s made without harsh chemicals like Formaldehyde, Toluene, or Acetone. Knowing it’s safe and non-toxic is a huge relief, especially if you are using it on children (it's safe for ages 1+)." Application & Appearance "The application is smooth and it dries very quickly (under a minute). It leaves a subtle, healthy-looking glossy shine on the nails. It can be used on bare nails or as a top coat over your favorite colored polish. Just remember to reapply every 2-3 days to keep the bitter taste strong, as it can fade after several hand washings." The taste can transfer to finger foods (like fries or fruit), so you may need to use utensils for a while!

Seriously works amazing! It’s been 2 days since I started to use it. And I can already tell you now the taste is horrendous. Has kept my fingers out of my mouth. Sucks when you eat finger food though cause once the taste goes into your mouth it makes the food taste bad. So you won’t want to eat. Which I guess secretly it helps you control your hunger and cravings haha. Really good product

I used this product for about a month. The tastes is pretty bad and does linger in your mouth. But what really helped is the psychological aspect—just knowing that I’ll have a gross taste in my mouth prevented me from biting my nails. Because, technically, you could get used to the taste, so I think this product works because of what it does to your psyche. Lol. I saw some reviews that cautioned people against using contacts while using this product. So, I did wear latex gloves to put my contacts in every morning for the time I used this product. I HIGHLY recommend this product. My nails are so beautiful now! :) I have no urge to bite them anymore. I give this four stars because of the fact that you’ll need to wear gloves to put in contacts and that the polish really does end up on your finger pads too and can ruin the taste of your meal. FYI: The photo shows two months of progress.

My daughter immediately stopped chewing her nails once she started using this product. Now she can finally get them painted!

**EDITED TO ADD: came back to say, I’ve only had to reapply twice and we are still THUMB SUCKING FREE! Praise be! I never write reviews but had to share my experience as a mom of a strong willed 5.5 year old thumb sucker! We applied the polish on both thumbs on Monday before school in the hopes to stop thumb sucking at school during this horrid cold/flu season. He sucks his thumb when concentrating, when bored, when watching shows or while teacher is teaching, and to self-soothe for bed ever since we sleep trained him at 4 mo old. I completely forgot that this polish STAYS ON for a while and bedtime was going to be impacted, but there was no turning back and we needed to kick the habit once and for all, including sleep! So we committed. He allowed us to apply, and it didn’t burn or anything (“this is to help with germs and keep you healthy.”) Dried very quickly. I put it on while we were in the car and it was dry by the time we walked into school. He accidently put his thumb in his mouth a couple times out of habit that day and every time he would promptly take it out with a big YUCK! He got upset, yes, but it deterred his thumb-sucking! A swig of water solved it. We gave him some fidgets to help keep his hands busy. That night, he got PISSED and demanded I “take it off” but of course, that wasn’t an option and we rode the wave of comforting him and letting him work through it. Nights 1-3 he would get up a dozen times with every excuse in the book to avoid going to bed but eventually fell asleep! And no thumb-sucking during the days! I was SHOCKED! He even stopped sucking by accident/out of habit by the second day! Last night was night 5 and he went right to sleep! I will say I noticed after his bath on Wednesday night that the polish was starting to peel off so I reapplied it then to both thumbs, even though he had stopped sucking by then. It dried quickly again but it doesn’t last as long as they say it does, keep that in mind. I still give 5 stars because guys….IT WORKS! I’m a believer and so so thankful because I was starting to think my kid would suck his thumb until college! Every kid is different but I’m telling you….its worth a try! Hope it works for you, too! I will come back and edit my review if anything changes.

It didn’t work for my 3 year old. At first, he cried and wanted it off. He then got use to it and continued to suck his fingers. Heavy sigh! I do appreciate the attempt at making something for this issue with not so bad ingredients. I however, got it on my finger and thought it was awful. So might just depend on how stubborn your kid is.

I just applied it tonight… but I did notice the warning label -which is a little concerning and unclear. I won’t put it on my child without testing it on myself first. I noticed it dried reasonably fast… then I tested it. 🤢 I don’t see how it wouldn’t work. Will update when we know if it works Update: it works. As long as it is on my daughter‘s nails, she tries not to put them in her mouth. There are times where she does put them in her mouth for whatever reason, and then she immediately wants to brush her teeth, which tells us her fingers were in her mouth to some extent.

My twins love to suck their thumb. It’s a habit. Tried all but no avail until we found this product. After every shower have to reapply to ensure it’ll work. Done for 7 days and now the thumb habit is non existence. Thank you!!

No funcionó, mi esposa siguió comiéndose las uñas aun con el producto en los dedos.
