Best beauty Decision ever!! 5* product which helped me regain confidence
Amazing product. Does what it says on the tin. I’ve bitten my nails for almost thirty years. I once stopped biting them for about six months but only because they were in artificial nails always. But there’s never been a time where I’ve had them exposed and not bitten. It’s been a real battle. My nails have therefore always looked bitten, unhealthy, malnourished and quite disgusting. I could only go on dates if I had fake nails. Playing pool, typing, holding a microphone or even gesturing became quite embarrassing with these nasty nails. I always felt embarrassed and disappointed in my self. I decided to try a bitter tasting polish as a fix. Best decision ever! This one tastes so Terrible and each coat lasts for days so you only have to reapply every 3-5 days depending on how often you wash. That means even though it’s a small bottle, it will last you months. I started using this on the 23rd of September 2018 and because of how bitter it tasted, the aversion started immediately. I stopped biting immediately but would initially still try to just have the fingers around my mouth but the taste is so nasty and long lasting that i actually became used to keeping my hands away from my mouth and even hated the idea of my hands going near my face. Do keep the bottle tightly sealed and clean as mine leaked and so it’s almost empty. However, even though I only used it for six weeks, I’ve now stopped biting my nails and instead obsess about having a healthy nail care regime which consists of pushing the cuticles back, painting them and applying nail hardener. My nails have grown leaps and bounds as you can see from the before and after photos (taken 6-7 weeks apart). I can now have a full manicure, paint them and flaunt my nails. They look amazing, I get complements from friends and family but they are quite weak due to extended Time spent biting for almost 30 years plus lots of gels, acrylic and stick on nails. So I am now rather focused on treating them and getting them strong and healthy. I can’t explain the joy, peace, confidence and freedom I feel from using this. It’s honestly changed my life. My family and friends are so proud of me. Thank God. Cheers to the manufacturers of this and the amazon seller. I’m so grateful: you changed my life.

THIS IS A MUST WORKED FROM DAY ONE FOR BOTH MY 3 AND 4 YEAR OLD.
Its been almost 3 weeks now and from the first time i put this on my children i have made them aware of what it's is,what it does, and why I am doing this to them. I have made them both taste on their nails. And every couple of days I put it on them without a fuss. They are only too willing to participate.... Bought this for my daughter and son as they both suck their thumbs(used to suck) I should say now with the help of this. They both were so addicted they could be walking down the road sucking their thumbs. They didn't care where or when they did it. From the first night putting this on my daughter(4) and tasting it she hasn't attempted to suck her thumb or I haven't seen her anyway and she was almost constantly doing it whenever she had a chance. It has well and truly put her off. And when asking her if she wants too I get a strange face with eewww no yucky.. my son(3) the first night he woke up crying I not sure if that's cos he tried to suck during sleep or If was a night terror as he had been suffering from them after being poorly with a very high temperature. He also is not wanting anything to do with his thumb now though.. no mummy yukky i get too.... I have also put on both my kids finger nails also as didn't want them stopping sucking thumbs and going to sucking their fingers instead. One bad habit to another. While doing this they have also stopped biting finger nails. Which wasn't so much of a problem for them but they don't do it at all now... I would definitely reccomend this to any parent who needs their child to stop sucking their thumb. I thought that it wouldn't work as their nails are so small but I have tried, and it doesn't only taste bad but lingers and spreads around the mouth. Leaving an awfully fowl uncomfortable bitter after taste in the mouth..They even made their big sister (22) suck their thumb as a joke and she gave a right good suck unaware that when she stopped the taste would rear it's ugly head.. the look on her face was a picture it just said it all..!!!!

I DID IT!
NAIL UPDATE Ive been biting my nails since i understood they were there. Ive never bitten the skin , just the nail and they are so SO bad. ive only managed to grow them a TINY bit around 10 times. i now have a little girl. I dont want her to see me do it and pick up the habbit. i feel embarssed about them every single day, esepcially when i hand someone money, retrieve something etc i always try and hide them but sometimes some people see and they cant hide their digust.. i cant blame them. If my nails get better ill feel confident to do a before and after. The taste of this is HORNEDOUS, its like a rotten chemical matal. The thing is, the taste stays in your mouth for a really long time. In a way its good as its makeing me resent the thought of biting my nails, its constantly reminding me to stay away which is good as alot of the time i dont even know im biting them. Bad thing is when you eat crisps, wraps, even an ice lolly. If your mouth goes near your finger or your finger on the food you will be guaranteed to get the polish taste which is NOT pleasant. Even drinking doesn't get it to go, just waiting. UPDATE _ Grown my nails after whole life without them? so i started my nail journey on the 27th March and the latest picture is from 13th May. It wasn't the easiest of journeys, sometimes I had the urge to bite and when I did I just put even more polish on. I have bitten a bit of each thumb. I felt awful after. I also chipped a nail and bit it to straighten it out....other than that it was surprisingly easy to stop, once I started seeing results I didn't want to do it. This polish definitely sped up the nail growth, in one day I saw results and you can see it in the pictures. It also adds a nice shiny coat to your nail so despite the awful taste.. it helped a lot. Spending my whole life with no nails becauze i was constantly destroying them, I was skeptical about what they'd look like when they did grow. I will say that they aren't as strong as most peoples, as time goes on they are getting stronger though. The shape isn't what I'd call normal? Maybe that's just how they are or maybe the biting played a part? It makes life so much easier, I can open bracelets and necklace charms, I can scratch price stickers off items. I no longer try and hide to my fingers when passing someone money, I dont feel ashamed anymore and it feels AMAZING like a weight has lifted. I'm even ordering some nail polish and a base coat to try and paint them :) I'm really excited. To everyone with a nail biting habit, you can do it!!!!

Wow! :)
Bitten my nails since before I can remember, but this stuff really works! After a few hours I was already pulling my fingers away saying: ‘urgh no way do I want that taste again :D’ Give this a shot :)

immediate results
having kept my nails short all my life through biting them,i found that i was chewing them shorter and shorter,so i decided to do something about it. having read the reviews i sent off for it and received it promptly. i excitedly read the instructions and although the instructions say apply at bedtime,i thought as the postman had made a special effort to deliver the post early that day,1.00pm,i applied it immediately. what a mistake that was! using it has involved me in incurring extra expense and forced life changing habits on me. for my evening meal that day i ate chicken using my fingers. another bad mistake! a foul numbing taste hit the roof of my mouth. i had forgotten the newly applied mavala to my fingers. some time later i had again forgotten about the mavala and attempted to extract the bits of chicken from between the ample gaps in my teeth using a combination of my tongue and finger. again i was immediately reminded what was on my fingers! thats where the additional expense comes in. i had to purchase some cocktail sticks from the local supermarket to use as toothpicks,as i was mortified at the thought of putting my fingers in my mouth again. my favourite method of eating yogurt is by dipping my forefinger in the pot and sucking the yogurt off my finger. that has had to change and whilst using mavala i have had to resort to using a spoon like the rest of humanity. i watched a dvd the other evening with my 5 year old grandson sat on my knee cuddled into me. i was eating chips from the takeaway using my fingers. i popped a chip into his mouth and immediately after swallowing it he screwed his face up in disgust and said indignantly "granddad,i have a disgusting taste in my mouth,and it wont go away!" a quick drink returned him to normality,and a plus point of the incident was that i didnt have to share any more chips with him as he thought they were the source of the taste. eating peanuts became a work of art as i had to make sure the peanuts entered my mouth without my fingers touching my lips,and sucking the flavour off my fingers became a definite no no. i am going to recommend mavala to my dentist. he doesnt bite his nails but i am sure it would be cheaper to give his patients a squirt of mavala into their mouth instead of anaestetic. i am not saying it would numb the pain but it would certainly occupy their minds. i have given the mavala a 5 star rating,but that says i love it. so really i should have given it 1 star because i hate it,but it gets 5 stars because it is an excellant product and does what it was purchased for extremely quickly. it is so good that i only used it twice,so i have unused mavala and unused cocktail sticks,because i am now back to eating yogurt with my forefinger and extracting foodstuffs from between my teeth with my tongue and finger. eating peanuts is now back to normal. i am now in possession of a lovely set of nails. i sit there admiring them and they seem to be screaming "bite me! if you dare!" that i dare not. i am considering offering my nails to a photographic modelling agency. i am sure that with the latest technology they would be able to airbrush the copious wrinkly skin off my hands and fingers. i see from reading other reviews that this product is used on children. if i was one of those children i would want the applicator prosecuted for child cruelty,even though my grandson would be getting it if he starts biting his nails! i dont think i will bite my nails again,not as long as the memory of the taste stays with me!

Tastes truly awful, transfers onto lips with ease, rubs off quite quickly.
I was a bit shocked at first with how small the bottle is but tbh I should have paid more attention to the size of the bottle. I don't think the tiny size is much of an issue as the brush is also tiny, and it's quite thin and you don't need a lot. I put on a thin coat, and let me tell you this tastes rank. This will not only stop you biting your nails, but also picking your teeth, or touching your lips in general (I sometimes put my thumb against my lips when I'm thinking, and it rubs off onto the moisture on you lips, and later when you lick your lips BAM oh god this tastes so bad!) Just avoid putting your fingers near your mouth at all costs! The taste is so, so strong. However, I only put this on a few days ago and it's rubbed off already. I only put a thin coat on, but it seems that it will need replication every week if it hasn't already helped you kick the habit. I definitely think this product has helped me with my nail biting habit (so far) and also other nervous habits like touching my mouth, it really does taste truly awful, but I'm not sure if another longer lasting product would be better (haven't tried another, can't tell you)

brilliant
I have been biting my nails for years and just could not stop. I have applied this and have not bitten my nails for the past 2 weeks as I hate the taste. I no longer put my fingers near my mouth. It is the only thing that has stopped me biting my nails. I highly recommend please give it a try.

A Bitter Solution to Break Bad Habits 💅🚫
As someone who has struggled with nail biting for years, I was eager to try Mavala's Stop formula in hopes of finally kicking the habit. This clear treatment polish promises to discourage nail nibbling with its intensely bitter taste. And for the most part, it delivers on that claim. The first thing I noticed after applying Mavala Stop is just how potent and lingering the bitter taste is. One little lick of your nail and you're met with an incredibly unpleasant flavor that forcefully reminds you to keep fingers out of your mouth. For determined nail biters like myself, that powerful aversive element is key. I also appreciated how the product goes on smoothly with a clear, glossy finish - no gloppy white mess. It wears well for a couple days before needing to be reapplied. The small 10ml bottle also lasts quite a while with regular use. However, there are a couple downsides to note. The intense bitterness can accidentally transfer to foods if you're not diligent about keeping your nails away from your mouth entirely. There's also no real way to "cheat" the system - even a tiny taste is enough to make you regret taking that nail-nibbling risk. Overall, Mavala Stop is an effective tool for combating nail biting and thumb sucking habits, especially for motivated individuals. The foul taste really does discourage those unconscious biting urges. Just be prepared for an incredibly bitter experience if you slip up, and take care not to get it in your food. For me, it's been worth the tradeoff to finally break this destructive habit.

Praise the Mavala!
My baby is 17 months old, and this worked in just one day. She started sucking her thumb around 3 months old and never took a pacifier. Since then, she always sucked her thumb in the car seat and while sleeping. I honestly found it hard to look at, but I planned to address it closer to age two, when she might better understand. Recently, she started sucking much more aggressively. The skin on her thumb became raw, cracked, and scabbed over, and it clearly looked painful. It also wasn’t healing even after a long time. I knew she was still very young, but at that point I decided to try this product. I do want to mention that the taste is extremely bitter. The first time she put her thumb in her mouth, she immediately stuck her tongue out, smacked her lips, and clearly hated the taste. She kept making faces and licking her lips in confusion — but that bitterness is exactly what made this work. The result was a complete success. She stopped sucking her thumb after just one day. The first night, she tossed a little in her sleep but didn’t cry and slept through the night. I plan to continue applying it for another 1–2 weeks just to be safe. I’m incredibly grateful for this product — the bitterness may be unpleasant, but it is truly effective.

Tolles Produkt <3
Beiße seit 30 Jahren Nägel. Seit 3 Wochen das erste Mal keine Nägel gebissen. Wahnsinnig effektiv. Die Substanz ist so unfassbar ekelhaft, dass schon eine kleine Berührung im Mundbereich reicht, um den Geschmack auszulösen. Habe fast das Gefühl, das dieser extreme Ekel dazu geführt hat, dass sich mein Hirn neu programmiert hat und Nägel beißen nicht mehr im Coping Repertoir ist. Kann nicht verstehen, wie manche Anwender trotzdem beißen können, habe sogar Bauchschmerzen bekommen von dem bitteren Geschmack.

Ottimo prodotto
Fa il suo dovere, se lo metti sulle unghie, stai pur certo che non le metterai in bocca per quanto è brutto il sapore. Mi sono ricresciute le unghie.

Werkt goed maar alles smaakt ernaar.
Bij bv fruit op de hand eten proef je de bittere smaak. Ik proefde hem de hele dag door. Blijft zeker 4 dagen werken.

Best product for nail biting!
It honestly works! I had tried everything and would always “get used” to the taste 😆 This product is expensive but it is worth every penny!! It lasts even if you shower, if you wash hands, days later - it’s still there. So absolutely you have no escape! If you’re in doubt, look no further - I was so dubious about spending the money and being another waste… but no way. Trust me… I hardly ever leave a review but I had to this time as I want to help people who are on the fence like I was!! It is amazing 🤩
