Keep your nails trimmed and clean
In order to stop nail biting, you need to keep your nails trimmed and clean. It is advisable to trim your nails straight and not in an oval shape. People mostly bite their nails because they are rough and jagged. In order to make them smooth, you can use nail clippers or nail file.
Apply nail polish
In order to make your nails less tempting, you can apply nail polish. Remember that some nail polish has a bitter tasting quality. You can always buy these types of nail polish in order to refrain from biting your nails. Keep in mind that if the nails taste bad, you will automatically avoid chewing on them.
Get a manicure
You need to have a manicure in order to prevent nail biting. When you spend money on making your nails look clean, you will not want to ruin them.
Buy rubber gloves and wear them. When you put them on, you will face difficulty in biting your nails as they will be covered.
You can apply behavioural therapy in order to prevent yourself from biting nails. You can tie a rubber band on your wrist and whenever you try to bite your nails, snap the rubber band so it hits your wrist very hard. With this therapy, your habit of biting nails will slowly diminish.
Take help from family or friends
You can always take help from your family members or a friend. Simply ask them to remind you to stop biting your nails whenever they see you doing it. When you take help from your family and friends, you will eventually get rid of this habit. Remember that by taking assistance, you will be gently reminding yourself to stop biting your nails.
Keep your mouth busy
In order to stop yourself from biting your nails, you need to keep your mouth occupied. Grab a few sticks of gum and chew on them throughout the day and you will notice that you are not biting your nails as much as usual.
