The Science of Nail Growth: How Long Do Nails Really Take to Grow?

We admire long, strong, and healthy nails—but have you ever wondered how long it really takes to grow them? Whether you’re waiting for a broken nail to recover, growing out your natural nails after acrylics, or simply curious, here’s a breakdown of the science of nail growth and tips to help you along the way.

How Fast Do Nails Grow?

On average, fingernails grow about 3 millimeters (mm) per month, which is roughly 0.1 mm per day. That means it takes about 3–6 months to fully regrow a fingernail from the cuticle to the tip. Toenails, on the other hand, grow much slower—only about 1 mm per month, taking 12–18 months to fully regrow (Gordon S, 2025).

What Affects Nail Growth Speed?

Several factors influence how quickly your nails grow:

Age: Younger people tend to have faster nail growth.
Health: Illness, nutritional deficiencies, or poor circulation can slow nail growth.
Hand dominance: Nails on your dominant hand often grow faster, likely due to increased blood flow from activity.
Season: Nails usually grow faster in summer thanks to better circulation.
Hormones: Pregnancy and certain hormonal changes can temporarily speed up growth.

Nail Growth Tips: How to Support Healthy Nails

While you can’t magically speed up nail growth overnight, you can create the best conditions for stronger, healthier nails:

Eat a balanced diet rich in protein, biotin, zinc, and iron. These nutrients are essential for keratin production—the building block of nails.
👉 Studies show biotin supplements may improve nail thickness and reduce brittleness in some people.
Moisturize nails and cuticles daily. Hydrated cuticles protect the nail matrix, where growth begins.
Protect your nails by wearing gloves during cleaning, gardening, or dishwashing to prevent damage.
Choose salon treatments wisely. BIAB and gel overlays are healthier long-term choices than harsh acrylics, as they strengthen and protect natural nails.
Avoid biting or picking. These habits damage the nail bed and cuticle, slowing growth.

Patience Is Key

Broken fingernail? Expect at least 3 months for full regrowth.
Toenail injury? Be patient—it can take up to 18 months to completely recover.
Post-enhancement recovery? If you’re growing out natural nails after acrylics, expect at least 6 months for them to regain strength and length.
