The Foundation of Nail Health

As nail care professionals serving Montreal for over 20 years, we have learned that truly beautiful nails start from the inside out. Understanding the science behind nail health helps you make informed choices.

Nail Anatomy 101

Your nails are made primarily of keratin, the same protein found in hair and skin. Understanding their structure helps explain proper care:

• Nail Plate: The visible hard part you polish
• Nail Bed: Skin beneath the nail plate
• Matrix: Where new nail cells form
• Cuticle: Protective seal against infection
• Lunula: The white half-moon at the base

Essential Nutrients for Strong Nails

Biotin (Vitamin B7):

• Strengthens keratin infrastructure
• Reduces brittleness and splitting
• Found in: Eggs, almonds, sweet potatoes, salmon
• Recommended: 2.5mg daily for nail health

Protein:

• Nails are primarily protein
• Inadequate protein leads to weak nails
• Sources: Lean meats, fish, legumes, dairy
• Aim for 0.8g per kg of body weight daily

Iron:

• Prevents vertical ridges and brittleness
• Deficiency causes spoon-shaped nails
• Sources: Red meat, spinach, lentils
• Pair with vitamin C for better absorption

Zinc:

• Essential for cell growth and repair
• Prevents white spots on nails
• Sources: Oysters, beef, pumpkin seeds
• 15mg daily recommended

Omega-3 Fatty Acids:

• Nourishes nail bed
• Reduces inflammation
• Prevents dry, brittle nails
• Sources: Salmon, walnuts, flaxseed

Hydration: The Overlooked Essential

Water intake directly affects nail health:

• Aim for 8-10 glasses daily
• Dehydration causes brittle, peeling nails
• Hydrated nails are flexible and resistant to breaking
• External moisture (oils, creams) complements internal hydration

What Your Nails Tell You About Your Health

Pale or White Nails: Possible anemia or liver issues

Yellow Nails: Fungal infection or excessive polish use

Blue Nails: Poor circulation or lack of oxygen

Ridged Nails: Aging, nutrient deficiency, or dehydration

Spoon-Shaped Nails: Iron deficiency anemia

Pitted Nails: Psoriasis or eczema

Note: Always consult a healthcare provider for persistent nail abnormalities.

Daily Care Practices Based on Science

Morning Routine:

• Apply cuticle oil (increases flexibility by 25%)
• Massage to improve circulation
• Protect with hand cream containing SPF

Throughout the Day:

• Wear gloves for wet work (prevents water damage)
• Avoid nail biting (transfers bacteria)
• Use nails properly, not as tools

Evening Routine:

• Cleanse gently
• Apply rich hand cream
• Consider overnight moisturizing treatment

The Role of Professional Nail Care

Regular professional manicures and pedicures contribute to nail health:

• Proper cuticle care prevents infection
• Expert assessment catches problems early
• Professional products are safer than DIY
• Correct technique prevents damage

Common Nail Damage and Prevention

Splitting and Peeling:

• Cause: Dryness, harsh chemicals, over-filing
• Prevention: Moisturize, wear gloves, use glass file

Breaking:

• Cause: Lack of flexibility from dehydration
• Prevention: Hydrate, use strengthening treatments

Discoloration:

• Cause: Smoking, dark polish without base coat
• Prevention: Always use base coat, avoid tobacco

Supplements vs. Topical Treatments

Both work, but differently:

• Supplements: Improve nail health from within, take 3-6 months to see results
• Topical Treatments: Provide immediate surface protection and nourishment
• Best Approach: Combine both for optimal results

Age and Nail Health

Nail growth and quality change with age:

• Growth slows by about 0.5% per year after 25
• Nails become more brittle and ridged
• Circulation decreases affecting nail bed health
• Extra care and nutrition become more important
