A nail tech’s guide to repairing weak, brittle nails
Are your clients’ nails weak, brittle or prone to breakage? Snap, we’ve all been there. Troublesome nails can be a common concern, especially during the colder months! Whether you’re dealing with brittle, peeling nail plates or weak, splitting edges, knowing how to identify these issues and recommend the right nail care routine is important for maintaining optimal nail health.
Understanding how to strengthen nails and treat brittle nail types is essential for delivering beautiful manicures and achieving your clients’ desired results. Whether you’re advising clients on a nourishing cuticle oil or the latest builder gel system, the right approach starts with understanding the condition of the natural nail.
It’s time to learn how to tackle your clients’ weak, brittle nails, so every client leaves with nails that feel strong, healthy and resilient.
What causes brittle nails?
Some clients may also experience changes in their nails due to ageing, nutritional deficiencies, skin conditions or underlying health concerns. Nails that are persistently discoloured, thickened, painful, lifting or unusually brittle may require assessment by a pharmacist, GP or other appropriate healthcare professional.
As a nail technician, you can help clients maintain healthy-looking nails by adapting your services, recommending suitable products and explaining the importance of ongoing home care.
How to strengthen nails: professional tips for nail technicians
1. Keep nails and cuticles hydrated
Dryness can leave nails feeling fragile and make them more prone to cracking. This can be particularly prevalent during the colder months, causing nails to break. A nourishing cuticle oil is a simple yet effective addition to any daily nail care routine, helping to condition the nails and surrounding skin.
Encourage clients to apply cuticle oil regularly, particularly after washing their hands and before bed. Nail and cuticle oils can also be incorporated into manicure services to enhance the experience and create a more luxurious touch while offering a great opportunity to upsell during appointments, supporting at-home maintenance.

2. Recommend a nail strengthener
For clients with weak or brittle nails who want a break from enhancements, a nail strengthener can be a useful addition to their routine. These products are designed to condition or reinforce the appearance of the natural nail, helping clients maintain a neat, polished finish while their nails grow.
The OPI Nail Envy range is an excellent option for clients who want to enhance their natural nails while adding essential strength and hydration.
3. Avoid over-filing the natural nail
Excessive filing and aggressive product removal can thin the natural nail plate, making it more vulnerable to splitting and peeling. Nail technicians should use the correct files and removal methods for the product being applied, avoiding unnecessary abrasion to the natural nail.
If a client's nails appear noticeably thin or damaged, consider whether a temporary break from enhancements would be beneficial. Focus on gentle nail care, regular conditioning and careful maintenance rather than immediately applying another layer of product.
4. Protect nails between appointments
Professional treatments are only part of the picture. Encourage clients to wear protective gloves when washing up or using household cleaning products, wear winter gloves outside during the colder months, and resist picking or peeling away gel polish.
Keeping nails at a manageable length can also help reduce snagging and breakage while damaged areas grow out. A consistent aftercare routine can help clients maintain their nails between visits.
How to treat brittle, splitting and peeling nails
Brittle nails treatment
For clients looking for a brittle nails treatment, recommend regular cuticle oil application, gentle filing and protection from harsh cleaning products. A suitable nail strengthener may also help improve the appearance and manageability of the nails.
If a client with brittle nails requests a gel manicure, then applying a rubber base coat is an excellent way to add additional strength and durability to the nails.
Split nails treatment
For minor splitting, carefully shortening the nail and smoothing the free edge can help prevent further snagging. Avoid aggressive buffing or applying enhancements over a damaged nail without first assessing whether the service is appropriate.
OPI Repair Mode can replenish weak, brittle nails, helping prevent them from splitting and breaking. Enriched with Ulti-Plex technology, this nail serum delivers up to 99% nail keratin repair for stronger, smoother and healthier nails. This can be offered as an add-on service or as a retail product for at-home maintenance.
Peeling nails treatment
A peeling nails treatment should focus on gentle care rather than trying to seal the problem beneath additional product. Recommend keeping the nails shorter, filing carefully in one direction where appropriate and applying cuticle oil regularly.
Avoid pulling away loose layers, as this can remove more of the nail plate and worsen the problem.
A nourishing cuticle oil is a great way to prevent peeling nails by keeping the nails and surrounding skin healthy and hydrated.
Can BIAB and builder gel help weak nails?
However, it's important to remember that BIAB and builder gel do not repair the underlying nail or automatically make natural nails healthier. The result depends on the client's nail condition, the product used, correct application and appropriate removal.
When to recommend BIAB or builder gel
For clients with weak nails, assess whether the nail plate is healthy enough for the service and whether the product is suitable for their needs. Explain the importance of maintenance appointments and avoiding picking or peeling the coating.

Fungal nail treatment: what nail technicians need to know
If you suspect a client has a fungal nail infection, follow your salon's hygiene and safety procedures and avoid applying gel polish, BIAB or other enhancements to the affected nail. Refer the client to a pharmacist or GP for appropriate assessment and advice about treatment.
If your client has fungal nails, a fungal nail treatment such as the Thuya fungal nail gel can help to prevent and treat fungal nails. Enriched with climbazole and rosemary oil, this fungal nail treatment actively fights fungal infections and contains essential antiseptic properties.
For nail technicians, maintaining clean tools, following disinfection procedures and avoiding cross-contamination are essential when treating fungal nail infections.
