One of the most effective treatments against excessive nail biting are cream-based ointments that deliver a potent, bitter taste directly to the cuticle. This bitter taste dissuades an individual from the desire to bite their nails. Some cuticle cream treatments, such as Control-It, also contain essential nutrients that have shown the ability to heal broken cuticles and diminish hangnails, further reducing what an individual can bite. Cream-based treatments generally need to be administered for a month or longer to provide long lasting results.
The more you focus on daily tasks, the less time you'll have to unconsciously begin biting your nails. It takes incredible focus to break the nail-biting addiction, and paying attention to other needs can keep you from concentrating on your habit. Also, try to keep your hands full. It will be much harder to bite your fingernails if you're holding a cup of coffee or similar object.
Try rubbing raw artichoke on them. They taste really bitter when you bite them. Also, be careful of fake nails because I heard from my friend that having fake nails on for a long time can cause damage, like can make them really thin and brittle and she said that her moms nails stopped growing. ( but I'm not sure if that's true)
Do what you think is best for your nails. I bite my nails too and I know how it is. You start from a period and then you stop for a time period it's very hard to stop but, you might bite your nails from your nerves or stress. I bite my nails over nerves. I get really nervous very fastly. Just set aside some time for you to realize who and what you are and how you function with your nerves.
Think about everything your hands have ever touched when ever you feel the need to bite them. Scenario----- "Oh hey I have to go and talk to that important person over there... * hand goes up to face * Wait a minute now, isn't this the hand that.... D: "
I was a chronic nail biter as an adolescent/teenager to the point they bled and hurt. My background is in psychology/neuroscience so I know this is a maladaptive beh indicative of anxiety/nervous affect(mood).1)Counseling may get at the root of WHY you do this in the first place. U may also find that a cognitive-behavioral counselor will offer more proactive ways to deal w/your anxiety/nervousness.Therefore, getting @ the ROOT cause of Y you do this, will def be the BEST method of breaking the habit 4 good.2) a clear, foul-tasting daily topical polish by Sally Hansen that gets in the back of your throat & is very hard to remove the taste, even by eating/drinking. However,u may NOT apply it every day to avoid the taste.3)if ok w/mom & affordable,y not get acrylic tips? By paying for the application, as well as the fill-ins every other week and every time you bite one off, (bc it's harder to, albeit, NOT IMPOSSIBLE!),it's a costly/aesthestic way to avoid ruining the way they look & cost.Finally, if this isn't an option, perhaps painting them daily to match your outfit may be conducive to not wanting to ruin the way they look by biting them.
Start painting them (assuming you're a girl) and ensure you always wear nail polish. Spending that much time painting them, only to bite and chip them, plus the taste is not pleasant. It worked for me. (:
Well when i started biting my nails out of anxiety, they gave me this clear fingernail polish and it was called No Bite and you apply it to your nails twice a day and when you go to bite on them, it has a really nasty bitter taste and it helped me... But i also had to not pick it off.. Hope this helps!!
I chewed mine BAD when I was a kid. My sister had long nails & would claw me so bad! What finally did the trick for me, was, I put rubbing alcohol in an empty pill bottle, & dipped my fingers in it every time I went to chew them. I haven't chewed them since! Good luck!
