Strengthening hair and nails: why collagen and vitamin C are the ideal combination

“My hair has been so lifeless lately.”
“My nails just break when I open a can.”

Sound familiar? You're certainly not alone. Many people notice their hair thinning or their nails breaking easily. Fortunately, there's an easy way to strengthen your hair and nails, without a complicated routine or expensive treatment.

Why Your Hair and Nails Weaken – The Main Causes

Strong, shiny hair and strong nails seem like a given, until they suddenly fail. The cause often lies deeper than just bad hair products. Below are the most common reasons.

1. Hair loss and brittle nails due to vitamin deficiency

Hair and nails are largely made of keratin. Various building blocks are needed for its production. If your body doesn't get enough vitamins or minerals, it will prioritize vital organs over skin, hair, or nails.

Common deficiencies that affect hair and nails:

Biotin : essential for keratin production.

Zinc : supports cell growth and repair.

Vitamins A, C and E : important for healthy cell structures.

A vitamin C deficiency can lead to ridges or brittleness in nails.

Because vitamin C helps form collagen, a deficiency can also indirectly weaken your hair and skin.

💡 Did you know? Besides vitamin C, zinc , vitamin A , and silicon (from bamboo extract) also play a role in collagen production. Collagen is essential for the strength and structure of your skin, hair, and nails. By combining these nutrients, you support your body's natural collagen production and protect existing collagen from breakdown.

2. Thin hair and brittle nails due to stress or hormonal changes

Long-term stress increases cortisol production, which shortens your hair's growth phase. Hormonal fluctuations (pregnancy, menopause, thyroid disorders) can also cause thinning hair and brittle nails.

3. Bad eating habits

A one-sided diet or crash diets quickly lead to deficiencies in building blocks like collagen and vitamin C. Without this combination, your body lacks essential ingredients for healthy hair growth and strong nails.

4. Seasonal changes

Many people experience temporary hair loss during fall and spring. Extra care and nutrient supplementation, such as collagen with vitamin C or collagen hyaluronic acid with vitamin C, can help maintain the elasticity and shine of hair and nails.

5. Age

As we age, our natural collagen production decreases. The result: thinner, drier hair and brittle nails. Supplementing with products like hydrolyzed collagen with vitamin C can make a difference.
