No More Biting Nail Bite Prevention

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!

My 4yo was still thumb sucking at night and when he's tired. Then one night I put this on his nails when he was sleeping. The first night was rough - he woke up multiple times upset and confused about his thumb suddenly tasting bad. By day 2 he stopped fully sucking his thumb, though he did lick his thumb a few times during the day to see if the bad taste had gone away. I reapplied 2 days thereafter again while he was asleep. It has now been a full week and no more thumb sucking! He remains confused how suddenly his thumb tastes bad.... I guess I'll confess when he's older lol. There is another popular brand that sells a similar product but this one appears to be more geared towards children (at least it is marketed that way) so I chose this brand instead. The flavor of the nail polish is not horrendous but it is sufficiently bitter that it is not pleasant.

**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.

I really wanted to love this stuff. First night putting it on our 18 month old it did the trick, she almost gagged when she tasted it. After that it didn't work at all. I re-applied several times per day but those thumbs went right back in her mouth during nap and bedtime. Will try a different brand.

Received 4/23/2026.Applies smoothly and dries fast. Tastes really bad. I am hopeful this will work.I will give an update in a few weeks and I’m am a long time nail biter😩🤣Update 5/13/2026It works great! My nails have grown beautifully. The taste was so horrible for me not to bit my nails. I will be continuing to use this. Only down fall is if you like finger foods you will taste the polish😅Update 5/15/2026I was able to paint my own nails (been years) and top it with Essie No Bite and still taste yucky😝I’m so glad I found something that works for me not bitting my nails.

Over 20 years I've been biting my nails. Over 20 years I didn't know I had ADHD and that nail-biting was "stimming". Over 10 years I thought if I just tried hard enough, I could stop. Over 20 YEARS, I would bite without even knowing I was biting.It's been 3 days now and I haven't bitten my nails even once. I went to... Oh, I went to. Without even realizing it. My mouth was VIOLATED by the most DISGUSTING taste. It was AWFUL! Snapped me right out of it.I'll update (hopefully with pictures) in a few weeks!

This polish is super effective. It’s not just bitter, it spreads through your whole mouth and lingers for a good 5-10 minutes. It also transfers as I found out from my 7 year old since she was rubbing her nails on her lips.

Excelente producto a mis niños les funcionó muy bn dejaron de morderse las uñas

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!!

Me encanta! Después de larga búsqueda le. Ayudado a mi hija para no morderse, lo usa constantemente ya que con las lavadas de manos se va quitando.

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