Nail picking, or onychotillomania, is a compulsive behaviour in which a person constantly picks at their nails or tries to tear them off. While occasional nail picking is normal, persistent nail picking can indicate underlying stress or an anxiety disorder. Onychotillomania is a likely underreported condition and has been associated with several rare clinical conditions, including Smith-Magenis syndrome and Lesch-Nyhan. Treatment options include therapy, trigger identification, and medication.

What You'll Learn

Nail picking is a recognised condition called onychotillomania
The term onychotillomania was coined in 1934 by a Polish dermatologist, Jan Alkiewicz, and is derived from the Greek words "onychos" (nail), "tillo" (to pull), and "mania" (madness). It is categorised as a body-focused repetitive behaviour disorder (BFRBD) in the International Classification of Diseases-10 (ICD-10) and falls under the umbrella of obsessive-compulsive and related disorders. However, it is not included as a separate diagnosis in the Diagnostic and Statistical Manual-5 (DSM-5) but is considered a form of skin-picking disorder or excoriation disorder.
Onychotillomania is often underrecognised and misdiagnosed due to patients denying their self-destructive compulsion and the variable and bizarre presentations of the disorder. It can be challenging to differentiate from inflammatory skin diseases and other nail behavioural disorders, such as onychophagia (nail-biting) and dermatillomania (skin-picking). Diagnosing onychotillomania typically requires a comprehensive examination, including a mental state evaluation, to identify any underlying mental disorders or comorbid psychodermatological issues.
Treatment options for onychotillomania include behavioural modification therapy, habit reversal therapy, and cognitive-behavioural therapy. In some cases, antipsychotic medications have been used successfully. Additionally, protective measures such as adhesive bandages or Cyanoacrylate glue on the proximal nail fold can help prevent nail picking and promote healing. It is important to seek help from a healthcare provider if nail picking has led to injuries or persists despite efforts to stop, as it may indicate an underlying anxiety disorder or other mental health condition.

It is associated with anxiety and other mental health disorders
Nail picking, or onychotillomania, is often associated with anxiety and other mental health disorders. While occasional nail picking is not a cause for concern, persistent nail picking can indicate underlying stress or an anxiety disorder. It can also be a nervous habit, done unconsciously or out of boredom.
Onychotillomania is a compulsive behaviour in which a person constantly picks at their nails or tries to tear them off. The term was coined in 1934 as "excessive, self-induced damage to the nail". It is derived from the Greek "onychos" for nail, "tillo" for pull, and "mania" for madness. This condition can lead to physical damage, such as changes in nail shape and appearance, known as onychodystrophy. The skin surrounding the nail can become red, inflamed, eroded, or crusted, and the nail may darken due to pigment cell stimulation.
The behaviour is classified as a body-focused repetitive behaviour in the DSM-5 and is considered a form of skin picking or excoriation disorder. It is often associated with other psychiatric disorders such as obsessive-compulsive disorder (OCD), phobias, depression, and even delusional disorders. In some cases, it has been linked to suicidal ideation.
If you struggle with nail picking, there are treatment options available. Cognitive behavioural therapy (CBT) is one approach that aims to increase awareness of the behaviour and replace incorrect thoughts with accurate facts. Another therapy is habit reversal training (HRT), which includes awareness training and competing response training to establish replacement behaviours for nail picking. Additionally, medication has been used successfully in some cases.
It is important to recognise your triggers and practice self-soothing techniques. Finding replacement behaviours, such as using a stress ball or engaging in creative activities, can also help. If you are unable to break the cycle on your own, seeking guidance from a mental health professional is recommended. They can help you understand the underlying causes and provide appropriate therapies or interventions to address the behaviour.

It can be treated with therapy and medication
Fingernail picking, or onychotillomania, is a recognised condition that can be treated with therapy and medication. Onychotillomania is a compulsive behaviour in which a person constantly picks at their nails or tries to tear them off. It is different from onychophagia, or nail-biting, and dermatillomania, or skin-picking. Onychotillomania is often associated with anxiety and can lead to physical injuries and infections.
Therapy is a common treatment for onychotillomania. Cognitive behavioural therapy (CBT) is a type of talking therapy that can help individuals with onychotillomania develop coping strategies and change their behaviour. CBT may include a technique called habit reversal training, which helps individuals become more aware of their behaviours and break bad habits. Other types of therapy that may be helpful include group therapy, peer support, and acceptance and commitment therapy.
Medications can also be used to treat onychotillomania. Antidepressants, such as selective serotonin reuptake inhibitors (SSRIs), are often prescribed to help manage the condition. Anticonvulsants can help control muscle movements, while antipsychotics can help balance brain chemicals. Nutraceuticals, such as the amino acid supplement N-acetylcysteine, may also help reduce the urge to pick.
In addition to therapy and medication, there are other strategies that can help individuals with onychotillomania. Keeping your hands busy with activities such as squeezing a stress ball or doing something creative can redirect the urge to pick. It is also important to identify triggers and try to avoid them. Keeping nails short and maintaining good skin care practices can also help reduce the behaviour.

Triggers should be recognised and replacement behaviours learned
Nail picking, or onychotillomania, is a recognised condition that involves the repetitive picking of nails and the surrounding areas like the cuticle. It is often associated with underlying mental health conditions such as anxiety, stress, anger, or even more serious psychiatric disorders. As such, it is important to recognise the triggers for nail picking and learn replacement behaviours to address the underlying causes and reduce potential harm.
Triggers for nail picking can vary from person to person and may be related to emotional states or external factors. For example, feelings of nervousness, stress, or anxiety can trigger the urge to pick one's nails. Identifying these emotional triggers can be an important step in developing strategies to manage the behaviour. It may be helpful to keep a journal or log of emotions and nail-picking episodes to identify any patterns or correlations.
External factors can also play a role in triggering nail-picking behaviour. For instance, seeing an uneven fingernail or a hangnail might prompt some people to start picking. In these cases, maintaining well-manicured nails can help reduce the likelihood of triggers. Keeping nails trimmed, filed, and smooth can remove potential sources of temptation. Additionally, covering the nails with adhesive bandages can serve as a physical barrier and reminder to avoid nail picking.
Once triggers are identified, it is essential to develop replacement behaviours to redirect the urge to pick nails. This can involve finding alternative ways to relieve stress or occupy the hands. Some examples include squeezing a stress ball, sitting on one's hands, making a fist, or engaging in creative activities like writing or crocheting. Exercise and sports that involve the hands, such as throwing or jerking motions, can also help release tension and provide an outlet for trapped anxiety.
In addition to self-management strategies, seeking professional help is an important option. Cognitive behavioural therapy (CBT) is a recommended treatment approach for onychotillomania. CBT can increase awareness of nail picking, challenge incorrect thoughts, and teach replacement behaviours. Other therapeutic approaches, such as habit reversal training (HRT), can also be effective. Medication may also be considered in conjunction with therapy, especially if an underlying mental health condition is contributing to the behaviour.

It can lead to nail and skin damage and infection
Nail picking can lead to serious nail and skin damage and infection. Onychotillomania, or the urge to pick at the nails and surrounding skin, is a likely underreported condition. It can lead to onychodystrophy, or changes in the nail shape and appearance. The skin surrounding the nail bed can become red, inflamed, eroded, or even crusted. The constant destruction of the nail bed can also lead to paronychia and darkening of the nail. In some cases, it can cause an itchy and painful lesion.
Nail picking can also lead to cuticle damage, which can be painful and lead to infection. The cuticle is the skin at the base of the nail, and it helps protect the nail bed from bacteria and infection. When the cuticle is damaged, it can leave the nail bed exposed to bacteria and other pathogens, which can cause infections. These infections can be difficult to treat and may require medical attention.
Additionally, nail picking can lead to habit-tic nail deformity, which presents as a longitudinal depressed groove involving the entire nail plate. It typically affects either one or both thumbnails. This deformity can be difficult to correct and may require medical intervention.
The good news is that there are several treatment options available for those who want to stop picking their nails. These include cognitive-behavioral therapy (CBT), habit reversal training (HRT), and medication. Some people also find it helpful to use adhesive bandages to cover the nails and protect them from further damage, or natural products with a bitter taste that deter nail biting and picking.
