A healthy diet plays a crucial role in maintaining strong hair, nails, and glowing skin. Deficiencies in key vitamins can lead to brittle nails, hair thinning, and dull skin. Fortunately, the right vitamins can help boost growth, improve texture, and enhance your natural beauty from the inside out.
In this guide, we’ll explore the best vitamins for healthy hair, strong nails, and radiant skin—and how to include them in your daily routine!
1. Biotin (Vitamin B7) – The Hair and Nail Growth Booster
