Understanding Nail Growth: Cycle and Growth Rate Explained

For professional manicures or nail modeling, it is essential to understand the fundamentals of nail growth. Only those who know how fast nails grow, what phases they go through, and which factors influence the growth can ensure long-lasting, well-groomed results.

At MONLIS School in Munich, one of Germany’s leading training centers for nail design, we emphasize anatomical knowledge – because high-quality work begins with understanding the natural nail.

Structure of the Natural Nail: The Basis of Growth

Before we dive into growth, it’s important to understand the anatomy of the nail. The natural nail consists of several parts:

• Nail matrix (growth zone): Where the nail plate is formed.

• Nail plate: The visible part of the nail extending over the nail bed.

• Nail bed: The skin beneath the plate – highly sensitive and well-supplied with blood.

• Cuticle (eponychium): Protects the matrix from infection.

• Nail folds and free edge: Frame and protect the nail.

Growth begins in the matrix – a cell layer that constantly produces new keratinocytes, which push the older cells forward to form the nail plate.

The Nail Growth Cycle

The nail undergoes a continuous biological cycle divided into three main phases:

1. Anagen phase (growth phase):
   New cells are formed in the matrix and push the older ones forward. This is the most active and longest phase – the nail grows visibly.
   
   

2. Catagen phase (transition phase):
   Cell production slows down, and nail growth is slightly reduced. This phase is brief and often goes unnoticed.
   
   

3. Telogen phase (resting phase):
   Nail growth nearly stops. Cells regenerate and prepare for the next cycle, which may take weeks or months.

How Fast Do Nails Grow?

On average, fingernails grow about 2–3 mm per month, or roughly 0.1 mm per day. However, growth rate varies from person to person.

Factors influencing nail growth:

• Age: Younger people generally experience faster growth.

• Season: Nails grow faster in summer than in winter.

• Circulation: Good blood flow supports cell production.

• Health status: Illness, medications, or deficiencies can slow growth.

• Lifestyle: Balanced diet, proper care, and physical activity promote healthy growth.

Why This Knowledge Matters for Nail Professionals

At MONLIS School Munich, we teach not only techniques but also biological understanding. Those who know the growth phases can:

• Plan refill appointments more effectively

• Identify potential issues early

• Use care products more intentionally

• Offer personalized client advice

• Ensure long-term customer satisfaction

Example: If refills are scheduled too early, nails may not have grown enough – leading to wasted product and time. If too late, lifting or breakage becomes more likely.

Fingernails vs. Toenails: Growth Comparison

A fun fact we always highlight at MONLIS: Toenails grow slower than fingernails – only about 1–1.5 mm per month. This is due to lower blood circulation and less mechanical use. In practice, this means.

• Pedicure appointments can be scheduled less frequently

• Products should be longer-lasting and more protective

• Refill intervals must be adjusted accordingly

Supporting and Stimulating Nail Growth

To support nail growth, the following tips are helpful:

• Use nail oils with biotin and vitamin E

• Massage the nail bed regularly

• Protect nails from moisture and chemicals

• Avoid biting or physical stress

• Eat a balanced diet (zinc, iron, B vitamins)

At MONLIS, we also discuss the role of nail care products – because only healthy nails can stay strong and beautiful long term.

The growth speed and biological cycle of nails are key factors in high-quality nail care and design.

At MONLIS School Munich, you’ll learn how to apply this knowledge in practice – to plan personalized treatments, optimize appointments, and deliver outstanding service to your clients.
