Mavala Stop 10ml -- Discourages Nail Biting and Thumb Sucking for Children and Adults, Transparent

This product has really helped me. I have been a nail/skin biter my entire life and it's a disgusting habit I've always wanted to change but found difficult as I bit my nails as a coping mechanism. As soon as I started using this product from day one I completely stopped. The taste is so bitter it really does put you off putting your finger anywhere near your mouth. The bottle is small but lasts a very long time as you only need to really apply it once every 4 days or so and even a small amount per nail will work. It does have a couple of downsides but easy to deal with. First is that I'm a man and it does make your nails a little shiny which is embarrassing but if you apply it the night before it should dull while you sleep and be more discreet. Secondly if you cook or eat with your hands you will get the taste on the food/in your mouth so make sure to use utensils where you can or get (disposable) gloves that are suitable for food handling. Overall though I still give the product full 5* since it is very effective at what it's advertised to do.

This product was fantastic. Our daughter stopped sucking her thumb within 3 days. We only had to use it once. Couldn't remcommend it more for those who are trying to encourage their children to stop thumb sucking.

I’ve been biting my nails since I was 7 years old. I take medication for anxiety, and I’ve tried using fake nails, but since I didn’t have a proper base to stick them on, the glue caused an allergic reaction. My fingers became itchy and developed pus, so I didn’t know what else to do. This is the first time my nails have grown long enough to reach the tips of my fingers. This product, despite being unpleasant, works amazingly well. Even after washing my hands multiple times a day, taking showers, and scrubbing my hair with shampoo and conditioner, the product stays on. It’s incredibly bitter—very, very bitter. The smell is typical for nail polish. I absolutely loved this product

This is the only product that helped me grow my natural nails. The bitter taste is absolutely horrible and there was no way I could bite my nails.

Oh my absolutely disgusting! Yes that's a good review. The problem with these products is you can't eat anything with your fingers. Crisps nuts sandwiches all spoiled if your fingers come contacts into your mouth. Even the dog won't take treats from me. The taste transfers a bit too easily but no more so than similar products

Got this for my husband and it worked so well. It lasted a few days in his nails as well as the taste which helped him to stop biting his nails. Also made eating finger food a but tricky as couldnt lick fingers without getting the taste in his mouth but was all worth it.

I've been a biter for 45 years or so. To the point where I remove 90% of the nail. It's unsightly, sore and now because of covid, dangerous. So, I need to stop. This product has some really good reviews, so I decided to give it a go..... It works..!! I'm actually growing finger nails.. I've been using it for about 3 weeks. However, couple of days ago I had a relapse. This stuff lasts for about 3 days even with hand washing, bathing, washing up etc etc, so I got a little lazy and didn't apply every day as I had been. So, apply every day, its part of the deterant. If you get this stuff in your mouth it's tastes vile. As it should, but, the taste stays in your mouth for a long time. It taints everything, food, water, tea, everything. The only down side for me is this, it taints everything you touch too. I know that I bite the skin around my fingers too. So I painted the whole of the front of my fingers. But, it transfers to anything even remotely moist ie, sandwiches, fruit, crisps, even pistachio nuts.

We have tried one other product and had some success with it, but then something happened in nursery and my 3 year old decided that she will go back to sucking her thumb. We left it a while and then tried this product. Its clear that the taste is awful, but it doesnt last as long for us as for other people (we had to apply it twice a day to have any effect). My daughter however quickly realised that if she sucks her thumb and doesnt swallow the saliva, she doesnt feel the awful taste. So she spits it out and puts her thumb back in :( I would definitelly give this product a shot if you are trying to stop nail biting/ thumb sucking.

It taste awful so it does the job properly

El producto es buenísimo, se lo puse a mi hija de 4 años y no se ha comido más las uñas! Sabe súper feo y si dura dos días. Eso si, el tratamiento se lo tuve que hacer 21 días no 10.

رائع جدا

Realmente é muito amargo, o ponto negativo é que é difícil comer as coisas com as mãos. Mas as unhas do meu filho estão muito melhores.

تحفه وساعد بنتي انها تبطل عاده مص الاصابع بعد محاولات كتير مع حاجات تانيه جاب نتيجه من اول استخدام لان طعمه مر حدا جدا
