Mavala Stop Discourages Nail Biting and Thumb Sucking, 0.3 Ounce

This product delivered. It not only stopped my 8 year old daughter from biting her nails, it helped strengthen them as well.My daughter picked up the nasty habit of biting her nails after we weaned her off the pacifier and sometime during pre-school. It was like heroin for her and no amount of talking or scolding helped. She was ashamed she could not stop and ashamed that her nails looked like ugly as hell. This was a HUGE problem. It seemed unfixable.I bought this as a last ditch effort, as my research online pretty much told me this would be a lifetime addiction.For the first 3 days, she resisted. She was upset, ashamed, etc.She would put her nails in her mouth, then spit out the nastiness, cry and complain.Then on day 4, it all turned around. She stopped putting her fingers in her mouth due to the nastiness, her nails became healed, and strong, and beautiful.She was so happy and proud. She saw the difference and actually welcomed having to put this on every few days. Actually, when it wears off and we forget to reapply, she STILL doesn't bite her nails.Last week, she went to the nail salon and put colored polish on, then the next day we re-applied this product over it, no problem!It's nothing short of a miracle.Not everything works for everybody, but for us, this was a godsend.Highly recommend you give it a try.

It works but you have to use it consistently. This is my second time purchasing this product. We stopped using the first bottle after my daughter stopped sucking her finger. She started sucking her finger again a year later. The liquid in the original bottle became hard and dry because it wasn't closed properly. The new bottle works like a charm and my daughter hasn't sucked her finger since. We still apply it every other day to ensure she truly breaks the habit.

Our son has been an avid thumbsucker for 3 years. This is the 1st product we tried, and so far our son hasn't sucked his thumb for 2 days!! He's tried, but has quickly been turned away from the very bitter taste. The only reason for not giving 5 stars is because the transfer of bitterness to finger foods and the gagging when he attempts to suck his thumb.

I got this for my daughter who was 7 at the time, we used it a whole weekend and it broke the cycle of her sucking her thumb. She had started to have an over bite when we went to the dentist, they are the one that recommended the product. It’s a little expensive but it’s so worth it!

I used this bitter nail polish to successfully break my finger-centric dermatophagia habit of 15 years.I applied it every day for a month (no exceptions) to my fingers. It made food I touched taste horrible, but this better served for breaking my habit of biting my fingers, as I learned to hate this stuff quickly.For people with a similar problem to myself, please consider giving this stuff a try. The key is to be consistent in your application of the polish.

Strong smell and it’s sticky

I think we used it twice and our daughter has not chewed her nails at all. she didn't believe me that its not poisonous so i put a tiny dab on a piece of paper and licked it. Super bitter taste that lingers for several hours. Completely disgusting but it works wonderfully.

This is the only product that I found that works. Used for both my son who bites his nails till they bleed and my daughter who sucks her thumb.
