The Hidden Dangers of Reusing Pumice Stones and Foam Blocks

1) They are porous

• The foam and pumice-like surface is full of holes. Skin cells, oils, blood droplets and microbes get pulled deep into the material.
• You cannot properly clean or disinfect a porous item. Disinfectants need a clean, non-porous surface and full contact time. In a spongey block, debris and microbes remain protected inside.
• Reusing a porous implement creates a real cross-infection risk for fungi, bacteria and viruses.

2) Hygiene rules and liability

• In many regions, reusing porous implements on multiple clients is not allowed under salon hygiene standards.
• If a post-service infection occurs and you reused a porous tool, it is hard to defend your practice or insurance claim.

3) Skin safety

• These blocks can remove skin too quickly. That increases the chance of micro-tears and makes feet more vulnerable to infection.
• Over-exfoliation disrupts the skin barrier. Clients can rebound with thicker callus, soreness or fissures.
• Never use aggressive abrasion on clients with diabetes, poor circulation, neuropathy or any open skin.

4) Product and tool compatibility

• Disinfectant soaking degrades foam and adhesives, so the tool sheds grit and becomes even less hygienic with each reuse.
• Bits of degraded foam can contaminate foot baths and are difficult to rinse away.

What to use instead

Safe Alternatives to Pumice Stones

• Stainless steel foot paddle with single-use adhesive grit pads. Use a fresh pad per client, then remove and discard. Clean and disinfect the metal handle between clients. There are a few good options on the market now, remember you need more than 1 that requires more investment – but in a professional salon it’s the only way to go.
• Autoclavable stainless steel tools with smooth, non-porous surfaces that tolerate proper cleaning and high-level disinfection or sterilisation.
• Single-use disposable files if a metal system is not available. One client only, then bin.

Technique tips for students

1. Assess first. Identify callus vs corns vs cracks. Refer when in doubt.
2. Soften safely. Use a professional callus softener (urea or lactic-based) or a short soak. Avoid over-soaking.
3. File with control. Light pressure, limited passes, and don’t “chase pink”. Focus only on thickened areas.
4. Stop at smooth. The goal is reduction, not baby-soft skin. Leave some protection.
5. Finish and protect. Rinse, dry thoroughly, then apply a targeted moisturiser with urea (10% urea is best) and don’t forget a good quality nail & skin oil to maintain results.
6. Home care advice. Daily emollient, weekly gentle reduction if needed, never use blades or “cheese-grater” rasps.

Why Pumice Stones Be Reused in Salons Is a Hygiene Risk

Reusing foam pumice blocks is a hygiene and safety risk because they are porous and cannot be reliably disinfected. Train students to choose non-porous, disinfectable tools such as a stainless steel foot paddle with disposable grit pads, follow a controlled reduction technique, and apply strict single-use and cleaning protocols.

Remember – if your doing your own feet – you can use what you like, for clients in a professional salon setting you need to take disinfection and sterilization seriously.

Superglue is not a cosmetic grade product and could trigger:

1. Allergic Reactions
   a) Allergic reactions are for life and it could be that you or your client will no longer be able to: 
   b) have dental work or implants
   c) Or that an orthopedic surgeon will not be able to glue any broken bones or wounds together should the need arise in the future

2. Cause the nail coating to become too hard
a) This can cause damage to the nail bed or hyponychium

3. Cause a chemical reaction that could lead to burns

Risks of Substituting Superglue for Resin in Fiberglass Nail Extensions

Using superglue instead of the recommended resin is not a smart thing to do.

In short: No you should not use superglue instead of the recommended resin for fiberglass nail extensions, the risk of problems arising is just to great.

Demystifying Nail Pterygium: Understanding Abnormal Skin Growth

Many don’t understand what nail pterygium is, but this nail professional apparently does. “Pterygium” is any abnormal growth of skin that becomes stretched. This can occur on any part of the body, on the eye, fingers, toes, elbows, etc.  When it occurs on the nail plate, it is considered an abnormal growth of skin. A true case of nail pterygium is most often a result of disease or injury  to the eponychium, as shown in the image below and occurs in three stages.

The eponychium slowly fuses to the nail plate, in three stages to create nail pterygium and prevents the cuticle from forming.

The Mechanism of Nail Pterygium Formation: Fusion of Proximal Nail Fold

Researchers who study these problems believe some types of pterygium occurs because the proximal nail fold fuses to with the nail plate, as shown.  The fusion is progressive until eventually all of the eponychium is fused to the nail plate. From this point, the proximal nail fold has become fused to the nail plate and will be stretched toward the free edge along with the nail plate in a triangular shape. Nail professionals should not try to cut, abrade, remove or reduce the pterygium, since that would be a medical treatment and outside the scope of allowed practices.

The fusion is thought to occur due to injury or disease, e.g. burns, physical trauma, lichen planus, and certain medical conditions also cause this abnormal growth. Such conditions should be referred to a doctor for examination if they have an unhealthy appearance. Pterygium should not be cut away by nail technicians, since it can bleed and become infected. It can be softened and conditioned, e.g. hot oil manicures.

Understanding Proximal Nail Fold Changes: Differentiating Pterygium from Overgrowth

Hardening and thickening of the proximal nail fold is not pterygium.  This tissue hardening, also referred to by some nail technicians as “overgrowth”, is often created by the nail service, e.g. by cutting, abrasion, or rough treatment. This is much like callous formation which occurs when the skin is repeatedly injured. If that is the case, the nail professional should eliminate the parts of the service that are causing the skin damage.

Eventually this condition may resolve itself.  The client may be able to have gentle manicures, without disrupting the pterygium, and eventually the tissue may recover from previous harsh treatment that caused its formation in the first place.  This recovery can typically take a month to several months to occur.

If the condition worsens, e.g. becomes red, swollen, tender or shows other signs of inflammation the client should be immediately referred to a medical practitioner; preferably a dermatologist (best for hands) or podiatrist (best for toes), so they can get a proper evaluation and treatment if needed.

No nail technician should take it upon themselves to “diagnose”, “treat” or prescribe treatment for this or any other medical condition. Practicing medicine without a medical license is forbidden by most countries, if not all. Find out how nail professionals can help with pterygium.

It’s essential to consider your well-being and that of your baby during this time. Here are some considerations to help you make an informed decision:

1. Chemical Exposure: Nail techs often work with various nail products that contain chemicals like acrylics, gels, and nail polish. While proper ventilation and hygiene are crucial, there is still a level of chemical exposure involved. It’s essential to minimize exposure to potentially harmful chemicals during pregnancy. Make sure the nail school provides adequate ventilation, and consider using a mask or working in a well-ventilated area.
2. Physical Demands: Nail techs spend long hours on their feet and may experience physical strain. Pregnancy can affect your energy levels and physical comfort. Consider whether you’ll be able to handle the physical demands of the training and the future job, especially as your pregnancy progresses.
3. Safety Precautions: Ensure that the nail tech school has policies in place to accommodate pregnant students. They should be willing to make reasonable adjustments to ensure your safety and comfort.
4. Timing: Consider the timing of your enrollment. If you’re in the early stages of pregnancy and feel comfortable with the potential challenges, you might proceed with the program. However, if you’re further along in your pregnancy, it may be more challenging to manage the physical demands of the training.
5. Consult Your Healthcare Provider: Before making a final decision, it’s crucial to consult with your healthcare provider. They can provide personalized guidance based on your specific health and pregnancy circumstances. They may offer insights into whether pursuing nail tech school is advisable at this time.

Ultimately, the decision to enroll in nail tech school during pregnancy depends on your individual circumstances and comfort level. If you do decide to proceed, ensure open communication with the school and your healthcare provider to address any concerns and make necessary adjustments to prioritize your health and the health of your baby.

Many are confused by “nail growth” claims.

The facts are, some of these claims are real and some are illegal. Why? There is a really big difference between “making” something grow and “helping” something to grow. All nail professionals, should clearly understand the difference.  For instance, if I put fertilizer on a plant, I “make” it grow faster.  If I put a fence around it to keep the rabbits from eating the plant, I “help” it to grow taller. There is a really big difference here. 

The first one changes or alters the way the plant would normally grow, while the second works by protecting the plant, so it can grow naturally.  It is illegal for cosmetics to claim that they MAKE the nail grow.  

Cosmetics are not allowed to change or alter the growth pattern or nails, hair or skin. Only drugs and foods can make these claims. Even so, cosmetics can “help” the nail plate to grow by making/keeping it in a stronger/tougher condition, which makes it more resistant to breakage. This is an important benefit that can allow the nail plate to survive daily rigors and to grow longer.

Watch for the term “helps grow longer” and avoid those who illegally claim to make the nail “grow faster”.  No cosmetic can claim to accelerate nail growth. If they do, that would make their product a misbranded drug. Words are important. A single word can make all the difference between a real benefit and a phony claim.

For detailed information on the safe levels of ingredients in gel and builder gel products, you would want to refer to a few primary sources:

Safety Data Sheets (SDS): Used to be MSDS but changed to a global recognition some years ago) Manufacturers of gel and builder gel products are required to provide SDS for their products. These sheets detail the ingredients, potential hazards, handling, and safety precautions. If you have a specific brand in mind, you can usually access their SDS directly from their website or by contacting their customer service.

The Cosmetic, Toiletry, and Fragrance Association (CTFA): They have a comprehensive dictionary that includes ingredient names and safety information. This can be an excellent resource for understanding the components in cosmetic products, including nail gels.

Regulatory Authorities: Depending on your region, national or regional regulatory bodies like the U.S. Food and Drug Administration (FDA), European Medicines Agency (EMA), or Health Canada provide guidelines and standards on cosmetic and nail product ingredients. These organizations often have databases or publications detailing safety levels and permissible limits of various ingredients. In the UK the regulatory organisation is the OPSS (Office of Product Safety and Standards) 

Professional Nail Associations & Publications: Industry-specific associations, magazines, and websites often have articles, studies, or discussions about the safety of nail products and their ingredients.

Educational Institutes: Since you mentioned theory education, consider reaching out to institutions offering courses in cosmetic chemistry. They may have resources or can point you towards detailed, scientific insights into nail product ingredients.

Remember, it’s always a good practice to stay updated, as research is continually evolving, and new findings emerge about ingredient safety for gel and builder gel.

Question: I’ve noticed that some people are using opaque, full-coverage nails with gel products like base gel or builder in a bottle. I’ve informed them that the opaqueness of these nails might prevent proper curing of the gel, leaving uncured gel underneath. I believe this is correct, but I’m struggling to find concrete information to support this claim, aside from the general knowledge that light must penetrate the gel layers for a complete cure. Can you help clarify this for me?

Expert: Of course! You’ve raised an important concern about the use of opaque, full-coverage nails in conjunction with gel products. Your understanding is indeed correct, and I can provide you with some insights into this matter.

Challenges of Using Opaque Nails with Gel Products

When it comes to gel products, particularly those that require UV or LED curing, the key factor is proper exposure to the curing light. Opaque or fully covered nails can pose a challenge because they act as a barrier, blocking the UV or LED light from reaching the gel product underneath. As a result, the gel may not cure properly, leading to several potential issues.

It is also important to remember that a gel coating is solid at only 50% of its required cure time, so do not fall into a trap of thinking because it appears to be solid, and there is no seeping residue, that a coating is fully cured. Add this to the risk of the opaque tip inhibiting the penetration of the wavelength of light, a nail professional will never be certain that the gel applied beneath is of the correct application thickness and achieved its proper cure.

One of the primary concerns is that the gel might not adhere securely to the natural nail when curing is incomplete. This can result in premature lifting, where the gel layer detaches from the nail, leaving room for moisture, bacteria, or fungi to enter. Additionally, incomplete curing can result in weakened nails and may even cause discoloration or yellowing.

Using Clear Tips and a Double-Cure Approach with Gel Products

To address this challenge, it’s recommended to use clear tips when working with gel products. Clear tips allow the UV or LED light to penetrate and ensure proper curing of the gel. Moreover, you can consider a double-cure approach, which involves curing the gel both before and after attaching the tip. This double-cure method helps confirm that the tip hasn’t obstructed the curing process and ensures a secure and long-lasting bond.

In summary, your concerns are valid, and it’s essential to choose clear tips and adopt a double-cure technique when using gel products to achieve successful and durable nail enhancements.

Q: Does cuticle oil truly break down traditional nail glue used to apply press-on nails? I see many people recommending cuticle oil to enhance longevity of wear, but then also recommending to soak in cuticle oil to remove the nails

There is no reason oil should break down nail adhesive (which is always a cyanoacrylate). Only acetone is truly efficient in this. It is, however susceptible to water. If there are air bubbles between the nail and the press on, it could work into those.

Those that are recommending oil to remove are probably using sticky pads instead of adhesives (which is safer and allows the press ons to be reused. Oil or warm water helps dislodge the sticky pads.

Exploring the Effects

The combination of acetone and oils in nail care has been a topic of discussion among professionals. In this blog, we will explore what happens when acetone is mixed with oils and examine the effects on nail care.

Understanding Acetone and Oils

Acetone: Acetone is a widely used solvent in the nail care industry, known for its effectiveness in removing nail polish and other coatings. It evaporates quickly, allowing for efficient and swift polish removal.

Oils: Oils, such as avocado or jojoba are commonly used in nail care for their moisturizing properties. They help keep the nails hydrated, preventing dryness and brittleness.

The Relationship between Acetone, Oils, and Evaporation

• Surface Evaporation: Evaporation occurs primarily from the surface of liquids. Molecules escape into the air, causing the liquid to gradually evaporate.
• Surface Area and Evaporation Rate: The rate of evaporation is influenced by the surface area. Containers with larger openings allow for faster evaporation due to their larger surface area compared to containers with smaller openings.

Effects of Mixing Acetone with Oils

• Slower Evaporation: When oils are mixed with acetone, the evaporation process slows down. This is because the presence of oils reduces the availability of acetone molecules on the surface for evaporation. As a result, the overall evaporation rate decreases.
• Concentration Effect: As more acetone evaporates, the concentration of oil increases, further slowing down the evaporation process. Eventually, all the acetone molecules evaporate, leaving the oil behind.
• Camouflaging Surface Damage: Oils mixed with acetone can help counteract the appearance of surface dryness and camouflage existing damage to the nails. They create a protective barrier and enhancing the overall appearance of the nails.

The Importance of Clarification and Scientific Validation

• Cautionary Note: It is important to approach conflicting claims or unfamiliar practices with caution. Not all information presented may be scientifically validated or accurate.
• Seek Professional Guidance: When encountering conflicting information, consult with chemists or reputable nail product manufacturers for accurate explanations and scientific validation. They can provide insights based on specific formulations and interactions.

Practical Considerations for Nail Care

• Balancing Moisturization and Drying Effects: Finding the right balance between the drying properties of acetone and the moisturizing benefits of oils is essential. Experimentation and personal preference play a role in determining the most suitable approach for nail care.
• Individual Results May Vary: Nail care routines can vary from person to person. It is important to consider personal preferences, nail conditions, and individual results when incorporating acetone and oils into a nail care routine.

Conclusion

Mixing acetone with oils in nail care can have various effects. The presence of oils slows down the evaporation process, leading to prolonged contact time and potential benefits for the nail plates and surrounding skin. However, it is crucial to seek scientific validation and professional guidance when encountering conflicting information. By understanding the effects of acetone and oils, and considering individual preferences, one can tailor their nail care routine to achieve healthy and beautiful nails.

Remember, taking care of your nails is a personal journey, and finding what works best for you may require some experimentation. Embrace the knowledge shared here and enjoy exploring the world of nail care!
