Specialist clinical hypnotherapy with Paul and Rebecca Smith for the automatic habit of biting nails. Most people need 2-5 sessions, in the Norwest clinic or via Zoom Australia-wide.
Nail biting is an automatic habit of chewing the nails, often during stress, boredom, or concentration. Clinical hypnotherapy at Norwest Wellbeing supports that habit change in the Sydney Hills clinic or via Zoom Australia-wide. Skin picking and hair pulling belong on their own pages.

Biting during meetings, screens, or focused work without noticing you have started
Growing the nails, then biting them down again
Hiding your hands, or feeling embarrassed about how they look
Sore cuticles, bleeding, or repeated infections around the nail
A stressful week that already includes more biting
Polish, gloves, or rules that last a few days, then fail
Paul or Rebecca talks through your cues, what you have already tried, and whether skin picking or hair pulling is the better page.
Guided relaxation and suggestion are built around your cues. You stay aware throughout. Sessions run in clinic or via Zoom. Age-appropriate work is available for children.
Typical reported improvement sits in a 75-85% range for many people within 2-5 sessions. The aim is a quieter automatic pull when the cue arrives, not complete freedom from ever wanting to bite.

Nail-biting-specific hypnosis trials are limited. Clinic-reported outcomes at Norwest sit in a 75-85% range over 2-5 sessions and are not a research finding.
Take our short screening quiz for a plain-language summary. It is not a diagnosis.
Nail biting, on this page, means an automatic habit of chewing the fingernails, often during stress, boredom, concentration, or waiting. The clinical name is onychophagia. The hand often arrives before a decision feels available.
This is habit-level support with Paul or Rebecca Smith. It is not a diagnosis of a body-focused repetitive behaviour disorder. Picking skin belongs on the skin picking page. Pulling hair belongs on the trichotillomania page.
Nail biting is commonly reported. There is no verified official Australian statistic that 20-30% of the population does it. What matters clinically is your pattern, not a national headcount.
Recognising a nail-biting habit often starts with small, repeated signs rather than one sore week.
Behavioural signs commonly include biting during meetings, screens, or focused work without noticing; growing the nails then biting them down again; and hiding hands.
Physical signs commonly include short uneven nails, damaged cuticles, soreness or bleeding, and in some people dental wear.
If the main behaviour is picking skin until it bleeds, or pulling hair, use those pages rather than folding them into this one.
Clinical hypnotherapy for nail biting works with the automatic loop: a cue, a hand, a bite, brief relief, then a stronger cue next time. Willpower talks to the part of you that already agrees. The loop is often faster than that part.
A session with Paul or Rebecca Smith starts with a clear map of your cues. Then guided relaxation and suggestion are aimed at those situations. You stay aware throughout.
This is not a claim that hypnosis changes the prefrontal cortex on an fMRI scan, and it is not a promise of complete cessation. The practical aim is a quieter automatic pull and a more available alternative when the cue arrives.
Research specifically on hypnotherapy for nail biting is limited. There is no large, high-quality evidence base that supports a single success percentage. The 75-85% figure on this page is Norwest Wellbeing's own reported outcome range over 2-5 sessions. It is not a research finding.
Bornstein, Rychtarik and colleagues (1980), in the International Journal of Clinical and Experimental Hypnosis, used a hypnobehavioural package with three highly hypnotisable adults in a multiple-baseline design. Nail length increased when treatment started. One of three showed some reversal at three months. That is a small case series, not a 75-85% trial.
Shenefelt (2003) reviewed biofeedback, cognitive-behavioural methods, and hypnosis in dermatology, including habit-related skin problems. That paper is a clinical review. It is not a 30-person nail-biting randomised trial.
Twohig, Woods, Marcks and Teng (2003) compared habit reversal training with a placebo conversation in 30 adults with chronic nail biting. Habit reversal produced a greater increase in nail length at post-treatment and five-month follow-up. That is behavioural evidence, not a hypnosis trial.
Taken together, hypnotherapy is a reasonable habit-change option to consider for automatic nail biting. Habit reversal has stronger trial evidence. This page is not a substitute for medical care if there is infection or dental damage.
Typical course 2-5 sessions
Clinic-reported 75-85% range
Paul and Rebecca Smith; habit-level support, not skin-picking treatment
The first session is a conversation with Paul or Rebecca Smith. They map when biting starts, what you have already tried, and whether skin picking or hair pulling is the better page.
Then guided relaxation and suggestion are built around your cues, not a generic willpower script. You stay aware throughout. Sessions run in clinic at Baulkham Hills or via Zoom Australia-wide. Age-appropriate work is available for children.
Later sessions review what happened in real situations. Most people need 2-5 sessions. Results vary.
Most people are surprised that hypnosis feels like focused calm rather than losing control. You hear the practitioner's voice and can stop the process at any time.
Norwest Wellbeing's own reported outcomes sit in a 75-85% range for many people within 2-5 sessions. That is a clinic-reported range, not a guarantee and not a finding from a large trial.
Some people notice a quieter pull within the first week. Others need the later sessions. Occasional testing situations, where the old cue shows up, are a normal part of changing a habit.
If there is infection or persistent bleeding, pause and speak with your GP. Lifeline is 13 11 14.

Most people need 2-5 sessions with Paul or Rebecca Smith. How automatic the cue is, and how long the habit has been running, can change that number. You will get a realistic view after the first conversation.
No. This page is for biting nails. Picking skin belongs on the skin picking page. Pulling hair belongs on the trichotillomania page. If more than one is present, say so at booking.
Yes, with age-appropriate techniques. Discuss your child's age and pattern when booking. We do not claim children always respond faster than adults.
The habit often starts before a decision feels available. Willpower talks to the part of you that already agrees. Sessions aim at that automatic cue rather than another set of rules.
