Lash Growth: Do Eyelashes Grow Faster in Summer?

If you’ve been wondering “do eyelashes grow faster in summer?” — the answer is yes, but there’s more to it than just warm weather.

Many clients notice their lashes looking fuller or healthier during the summer months, and this isn’t a coincidence. Seasonal changes can influence the natural lash growth cycle, affecting both growth speed and retention.

In this guide, we’ll break down exactly how lash growth works, how summer impacts it, and how to maintain long, healthy lashes all year round.

How Fast Do Eyelashes Grow?

Eyelash growth follows a natural cycle made up of three phases:

• Anagen (growth phase): Lasts around 30–45 days

• Catagen (transition phase): Follicle shrinks and growth slows

• Telogen (resting phase): Lash sheds and new growth begins

On average, eyelashes grow around 0.12–0.14 mm per day, though this can vary depending on your health, age, and lifestyle.

Do Eyelashes Grow Faster in Summer?

Yes — eyelash growth can increase slightly during the summer months due to several biological and environmental factors.

1. Increased Blood Circulation

Warmer temperatures improve circulation, delivering more oxygen and nutrients to the lash follicles, which supports faster growth.

2. More Vitamin D Exposure

Sunlight boosts Vitamin D levels, which play a role in regulating the hair growth cycle and supporting stronger, healthier lashes.

3. Seasonal Hair Growth Patterns

Research shows that hair growth tends to peak in late spring and summer, meaning your lashes may naturally grow quicker during this time.

Why Your Lashes Might Not Look Fuller in Summer

Even though growth can increase, many clients notice poor lash retention in summer.

This is due to common seasonal factors such as:

• UV exposure weakening the lash structure

• Chlorine and saltwater drying out lashes

• Sweat and oils breaking down lash adhesive

• Dehydration affecting hair health

So while your lashes may grow faster, they may also shed sooner if not properly cared for.

How to Improve Lash Growth and Retention in Summer

If you want longer, fuller lashes during the summer, focus on both growth and protection.

Keep Lashes Clean

Regular cleansing removes sweat, SPF, and oils that can affect Lash extension retention.

Avoid Excess Heat & Rubbing

Heat and friction can weaken both natural lashes and extensions.

Stay Hydrated

Hydration plays a key role in healthy hair growth—including your lashes.

Book Regular Lash Extension Infills

Maintaining your appointments ensures your lashes always look full, even with natural shedding cycles.

Use a Lash Serum

A high-quality lash serum can support the growth phase and strengthen lashes from the root. DO NOT use a serum on lash extensions - but perfect for lash lift aftercare.

Lash Growth in Summer: The Final Verdict

So, do eyelashes grow faster in summer?

Yes—but growth alone isn’t the full picture.

While warmer weather and increased Vitamin D can boost lash growth, factors like sun exposure, swimming, and dehydration can negatively impact lash health and retention - especially affecting eyelash extensions.

The key to beautiful summer lashes is combining natural growth support with proper aftercare and professional maintenance.
