Recognising Contra-Indications

At HONA we understand the importance to both nail techs and clients of understanding how to spot a nail abnormality or signs of an infection. A key part of being a nail tech is offering a safe and professional service that prioritises client health! While we’re not doctors and can’t diagnose, we can recognise when something isn’t quite right and guide clients towards the right support! Let’s dive in.  

Contra-indications VS Contra-actions 

First things first, it’s important to understand the key differences between contra-indications and contra-actions, as both play a crucial role in maintaining client safety and ensuring the best possible service.

• contra-indications – conditions that may prevent you from carrying out a treatment, either temporarily or permanently. These could include infections, skin disorders, or medical conditions that make a treatment unsafe. Identifying these early helps prevent potential harm and ensures your client gets the right care.
• contra-actions – reactions that can occur during or after a treatment. These might include skin irritation, allergic reactions, or sensitivity. Recognising and responding to contra-actions quickly can prevent discomfort and reassure your client.

understanding these terms isn’t just about following best practices, it’s also about protecting your clients, your reputation, and your business. by being aware of potential issues, you can make informed decisions, provide the right advice, and ensure every treatment is carried out safely and professionally.

Examples of contra-indications in nail services?

now that we understand what contra-indications are and why they matter, let’s take a closer look at some common examples in nail services. recognising these conditions is essential for providing a safe and professional treatment. some contra-indications may require you to adapt your service, while others may mean postponing the treatment altogether. being able to identify these early ensures both you and your client are protected.

Bacterial Infections

Bacterial infections appear red, swollen, and tender, sometimes with pus (abscess). Cellulitis can cause warmth and pain. Do not proceed with treatment—advise the client to see a GP.

Fungal Infections ("Greenies")

Caused by trapped moisture under enhancements, pseudomonas (greenies) appear as green discolouration. Remove enhancements, keep nails dry, and educate clients on hygiene.

Tinea Versicolor

A non-contagious fungal skin condition causing pale patches. Safe to proceed with service.

Eczema (Dermatitis)

Can cause itchy, red, or flaky skin. Not contagious, but avoid drying agents like acetone or alcohol on affected areas.

Diabetes

Diabetic clients are prone to infection and slow healing. Use non-metal files, avoid nippers and scissors, and ensure strict hygiene. Do not treat if they have loss of sensation—refer to a GP.

Warts & Verrucas

Caused by HPV, warts are contagious, so avoid treatment. Verrucas (on feet) require a waterproof dressing.

Skin Cancers (Basal & Squamous Cell Carcinoma)

May appear as persistent sores or abnormal growths. Not contagious, but advise the client to consult a GP if you notice anything unusual.

Psoriasis

An autoimmune condition causing scaly, silver plaques. Safe to proceed, but avoid drying chemicals on flare-ups.

Hives

Can result from allergic reactions. Identify potential triggers and avoid known allergens during treatment.

Herpes (HSV)

Highly contagious blisters, often on lips or hands. Do not proceed if active: wait two weeks after clearing.

Rashes & Viral Exanthem (Measles, etc.)

Red, widespread rashes from viral infections can be contagious. Do not proceed: advise medical consultation.

Scabies

Extremely itchy, contagious rash caused by mites. Do not proceed: client should seek medical treatment.

What to do when you come across a contra-indication

When encountering a contra-indication, it's crucial to communicate openly with clients. we must explain that we've identified an abnormality and prioritise their well-being by refraining from proceeding with the treatment. our aim is to avoid exacerbating any existing conditions. while we don't want to cause unnecessary concern, it's important for clients to understand that their health takes precedence over nail aesthetics.

While we cannot diagnose, the best course of action is to remove all products from the affected area and advise the client to visit their gp for further assessment. this ensures their health is prioritised while preventing potential complications. it’s also important to note that attempting to diagnose or prescribe medication beyond our scope of expertise could pose risks for both clients and nail technicians.

Working with allergies

For nail technicians, identifying potential nail allergies in clients is crucial for ensuring their safety and well-being. Here are some insights and advice to help you recognise signs of nail allergies:

• Familiarise yourself with common allergens: Learn about common allergens found in nail products, such as HEMA, HPMA, and IBOA. Be aware of the symptoms associated with allergic reactions to these substances.

• Observe client reactions: Pay attention to any adverse reactions or sensitivities your clients may experience during or after nail treatments. Look for signs like redness, itching, swelling, or irritation around the nail area.

• Have an in-depth consultation with new and existing clients re medical history and allergies

• Remove builder gel every 2-4 infills to check the health of the natural nail and ensure no contra actions are occurring

• Remove builder gel or gel enhancement if a client expresses any sign of change since their last appointment

• Ask about previous reactions: Inquire about any history of allergic reactions to nail products or other substances. Clients with a previous allergy may be more susceptible to developing reactions in the future.

• Educate clients: Provide information to clients about the potential risks of nail allergies and the importance of reporting any unusual symptoms or reactions. Encourage them to seek medical advice if they experience persistent or severe symptoms.

Important Notice 

Please note: If someone is already experiencing an allergic reaction or has explained that they have in the past and they don’t know what they are allergic to, they could still react to HONA or any other hypoallergenic ingredient. Speak with your insurer for advice on patch testing someone who has an existing allergy.

By staying vigilant and proactive in identifying potential nail allergies, you can help ensure a safe and comfortable experience for your clients.
