Review: A miracle cure for nail biters! - "Taste the Mavalaaaa!" is what my husband screams when he accidentally puts his nails in his mouth. He is a chronic nail biter who always gnaws his claws down to the quick, and so he's never had the white show on his fingernails before. After using Mavala every day for a couple of weeks, his nails were long enough that he actually needed to cut them with clippers! I was ecstatic! But wait! There's more! It's not just a temporary fix. After those weeks of regular use, he had become completely conditioned (read: disgusted) to stop biting his nails, even once we ceased applying the Mavala. It forced him to acknowledge his subconscious habits, and the bitter taste was unpleasant enough to deter him from idly biting his nails. Truly the miraculous cure you've been needing for you or your loved one's nail biting! More about this product: It comes in a nail polish-style bottle with an applicator brush in the cap. It also applies much like a clear coat nail polish, not like a thin liquid, as I originally thought it would. As such, it adheres to the nail like a glue, making it pretty difficult to wipe, lick or wash off by accident (or on purpose, muahaha). You need to use only a little bit, on the edge of your nail (if you're a biter). One application will last you the entire day, sometimes a little into day two. My advice for success with this product: Just remember that any bad habit dies hard. We purchased Mavala several months ago and stopped using it when my husband stopped biting. He went several bite-free months, but since then, times have been stressful at work and he occasionally relapses into nail-biting. If this happens to you, immediately go back to Mavala! Always keep it handy. Put it in your desk at work or keep it in your purse or car. Just remind yourself how horrible it tastes! You're much better off with this stuff to help you stop chewing. Also try applying it earlier in the day, before you go to work/school/places where you tend to bite your nails the most. Avoid eating finger foods and touching your lips (or at least be very careful)! Popcorn, pizza, sandwiches, etc. are a nightmare to eat with Mavala on. Even if you are behaving, the flavor tends to rub off on anything you touch. My husband has even given me a hello kiss after a long day at work where he struggles with biting his nails. Even THAT brief contact transferred the taste of Mavala to my lips, blegh! All that being said, I cannot testify to any of its other uses (such as to deter thumb sucking), but I do highly recommend it to anyone with a nail-biting problem. Be consistent, have the discipline to apply it every day, and correct yourself when you catch your bad behaviors. You will have healthy nails in no time! :)
Review: The best, worst product on the planet. - I have been a nail biter most of my life and I wanted to stop. I tried everything I could think of to try to stop biting my nails. And this is something I would do subconsciously. I would do this while sitting watching tv, reading a book, magazine or computer and when I am bored. Enter Mavala Stop. I would sit here on desertcart and other websites reading reviews and just about every review I would read raved about this product for helping them quit biting their nails or keeping their children from sucking their thumbs and fingers. I had my doubts reading these reviews but I decided to take the plunge. I got this product on Monday, right after Easter, and applied this product. I forgot I had this product on my fingers and put them to my mouth. The taste. OH THE TASTE!!!! I'd swear the same sadists that created "The One Ring ' in the bowels of Mordor, created the taste of this product (those that have watched "The Lord of the Rings" movies or read the books will get this reference). It is the most vile, horroble bitter taste I have ever tasted. The taste sticks to the inside of your mouth and stays there for a long time. There is nothing you can do to get the taste out of your mouth once its there. Plus, not only does the taste stick to your mouth and tongue, it sticks to your lips and around your mouth. So anytime you lick your lips or anywhere surrounding your mouth, you get that taste as well only not quite as strong. As far as how well the product lasts, it seems to have some staying power but leads to one of my complaints about the product. It seems to have a weakness to soap when you get a bath or wash your hands. It knocks the taste of the product down a good bit, especially after getting a bath. So if you reapply this after getting a bath, you should be good. If you can spare getting soap on your fingernails though the bad taste does seem to last but does get somewhat weaker over time. I can't speak to how the product works on children, but I can speak for an adult and this product does work. I have been using the product for a week and after that first day, I have rarely put my fingers to my mouth as I don't want to taste that taste in my mouth. It does effect eating snacks like popcorn and potato chips as well as eating finger foods. But now, I don't bite my nails, and for that...this product is a really good thing. In closing, if you are a nail biter and you want to quit? Please, I implore you... get this product. Yes, it tastes horrible and nasty but it works wonders. If it can help someone who has bit their nails for the last 33 years plus then it will help you, too.

## Questions & Answers

**Q: If applying this every day, about how many days does .3 oz last?**
A: First, you don't need to apply every day. It stays on for at 2-3 days. Secondly, the bitter flavor is so strong you don't have to use much each time you apply, so it lasts AWHILE. We barely made a dent in it by the time my daughter completely stopped wanting to suck her thumb.

**Q: Can it be used on cuticles**
A: The bitter taste would help stop cuticle chewing. I haven't used it specifically for that purpose and don't know the long term effects i.e. damage to cuticles. I would say its safe to use and effective on the cuticles if not used very often or very long. For more accurate answers please contact the manufacturer.

**Q: can I put it on silicon pacifiers to break my toddler from that habit?**
A: I would not. What I did was switch pacifier brands to one with a different shape. My child tried it and didn't like it and stopped needing a pacifier in a few days, since the old one was unavailable. I think switching instead of just removing it entirely lessened the crying.

**Q: What is the recommended age? I have a 2 yr old baby girl who suck her thumb a lot :(**
A: A relative of mine used it to curb thumb sucking on her 2 year old son. Not only did it cure the thumb sucking problem, but he was very happy to brush his teeth. Use just a tiny dab on his thumbnail and the problem will be solved. You should also try a tiny dab just to know of strong and how awful this stuff really tastes.

### ⭐⭐⭐⭐⭐ Thumb Sucking Stopped Immediately!!!!!! Thrilled Mom and Child!
*by C***L on May 6, 2008*

I have never written a review on Amazon before, but feel that if you have a child who can't stop sucking his/her thumb: read this! My six year old daughter sucked her thumb very often. She could not be stopped: in the car, watching t.v., at bedtime. Basically, if she wasn't talking or using her hands, her thumb was in her mouth. We tried bribery, we tried a band aid, we tried a glove. Then I brought a product called Thum that I saw at the drugstore. This is also painted onto the fingernail. She could wash it off (and did so at school) and it faded quickly so the spicy cayenne pepper taste would lessen and she could tolerate it. I was ready to order a hypnosis CD to assist with breaking the habit, via Amazon, when I found a link to Mavala. I read a handful of reviews and besides one unhappy parent. It seemed this might be the product that worked. My dentist said once her permanent teeth started coming in she would need to cease the sucking. We had considered having a retainer-like instrument put in her mouth that blocks the thumb from fitting in, though my dentist even described it as "cruel" and "a last resort". I applied the product to my daughter's thumb and she struggled emotionally when she realized, after tasting it, that she could no longer suck. A few tantrums occurred which we assist her through by distracting her with book reading, a bubble bath and lots of love and encouragement. She insisted that she couldn't have her blanket because it gave her the desire to suck even more. The taste: I touched my tongue to her nail and the taste is truly awful, a sour acidic chemical taste that dulls the tip of the tongue and then the taste shoots down both sides of the tongue. It lingers for quite some time. I took the advice of another reviewer and kept a glass of water by her bedside, When she would unconsciously suck her thumb while sleeping the putrid taste would wake her up and she would drink the water and fall back to sleep. It is day 6 and my daughter is doing fantastic. She doesn't like to talk about it, but her confidence is visible and my husband and I are overjoyed! I know first hand the difficulties thumb sucking can cause, I sucked my thumb until I was 12, so the desire I know, is strong. I went through braces, neck gear and needed to be re-taught how to swallow properly via a speech therapist. Try this product! MAVALA Stop for Nail Biting and Thumb Sucking
