How Metabolism Influences Eyelash Growth

The growth and appearance of natural eyelashes may seem primarily influenced by external factors — cosmetic products, makeup habits, UV exposure or professional treatments. However, the foundation of strong and healthy lashes begins much deeper: inside the body. A key element in this process is the metabolism, which supplies the hair follicles with energy, nutrients and oxygen.
At MONLIS School Munich, future lash professionals learn not only application and styling techniques, but also the biological principles behind healthy lash growth. Understanding these processes enables safe, effective, and long-lasting results.

1. What Is Metabolism and Why Does It Affect Eyelash Growth?

Metabolism refers to all biochemical processes in the body that produce energy, regenerate tissues and maintain healthy cell function. Eyelashes, like all body hair, are made of keratin, a protein that can only be formed if the body receives:

• Amino acids

• Vitamins

• Minerals

• Sufficient oxygen supply

If the metabolism functions well, the lash follicles receive everything they need for growth. If it is weakened or imbalanced, lashes may grow slower, thinner, weaker or become brittle.

2. The Eyelash Growth Cycle and Its Dependence on Metabolism

Every eyelash grows in three phases:

1. Anagen Phase (Growth) – the lash is actively formed

2. Catagen Phase (Transition) – growth stops

3. Telogen Phase (Rest and Shedding) – the lash falls out naturally

A healthy metabolism helps prolong the anagen phase, resulting in fuller, stronger and denser eyelashes.
If metabolism is disrupted, the growth phase shortens — eyelashes become finer and fall out more quickly.

3. Internal and External Factors That Influence Eyelash Growth

Several factors affect the way metabolism supports eyelash growth:

• Nutrition: Deficiency in iron, zinc, biotin, or omega fats weakens hair structure.

• Hormones: Thyroid disorders, pregnancy, or menopause can speed up or slow down growth.

• Stress: Elevated cortisol suppresses follicle activity and accelerates shedding.

• Sleep Quality: Cellular regeneration occurs mainly at night.

• Medications: Some prescriptions can affect hair cell division and renewal.

At MONLIS School Munich, students learn how to recognize these factors and advise clients accordingly to preserve natural lash health.

4. How Professionals Can Support Healthy Lash Growth

While lash stylists cannot directly change metabolism, they can help create the best conditions for healthy growth:

• Choosing gentle, high-quality materials

• Removing lash extensions carefully without pulling

• Recommending lash serums with peptides and vitamins

• Advising proper cleansing and daily care routines

• Offering guidance on lifestyle habits that support hair growth

The goal is to ensure that natural lashes remain strong and resilient, even when clients choose regular extensions or lifting.

5. Why Professional Education Matters

Every treatment — lash lifting, extension, tinting, or correction — must take the natural lash condition into account.
At MONLIS School Munich, students learn to:

• Identify lash growth phases correctly

• Recognize signs of weakened follicles

• Apply techniques that protect natural hairs

• Develop personalized treatment strategies for each client

This leads to results that are not only beautiful — but professionally safe and sustainable.

If you want to master eyelash treatments that enhance beauty while protecting the natural lash structure, the MONLIS School Munich offers hands-on, structured training programs for both beginners and experienced stylists.

Beautiful eyelashes begin within — and are perfected by professional knowledge.
