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 poor hair products. Below, we explain the main causes.

1. Vitamin A deficiency & hair loss

Your hair and nails are made up of keratin , a protein that your body produces itself, but for which it needs the right building blocks.

When your body doesn't get enough of certain vitamins or minerals, it starts prioritizing: vital organs first, then skin, hair, and nails. The result? Reduced keratin production, slower growth, and poorer quality.

Common deficiencies that affect hair and nails:

Vitamin A: Vitamin A deficiency can cause hair loss.

Biotin : essential for keratin production.

Zinc : supports cell growth and repair.

Vitamin C and E : important for healthy cell structures and protection against damage.
