Lash Retention 101: How to Make Your Extensions Last Longer
Lash retention is one of the most important factors in keeping your clients happy and coming back for infills. If your clients are experiencing premature shedding, they may assume it’s due to poor application—when in reality, many factors affect how long their extensions last.
In this post, we’ll break down everything you need to know about lash retention, from the science behind it to practical tips for both lash artists and clients.
What Is Lash Retention?
Lash retention refers to how long eyelash extensions stay attached to the natural lashes before shedding. On average, properly applied lash extensions should last 4–6 weeks, with clients typically returning for infills every 2–3 weeks.
Poor retention can be caused by several factors, including:
• Incorrect application
• Humidity and temperature imbalances
• Client aftercare habits
• Natural lash health
Understanding and addressing these issues can significantly improve retention rates and client satisfaction.
Top Reasons for Poor Lash Retention
1. Incorrect Application
Even the best adhesives won’t work if lash extensions aren’t applied correctly. Common mistakes that lead to poor retention include:
❌ Not isolating lashes properly – Stickies cause lashes to shed prematurely.
❌ Using too little adhesive – The bond won’t be strong enough to hold.
❌ Using too much adhesive – Excess glue can create a brittle bond that snaps off.
❌ Wrong drying time – If the adhesive isn’t fully cured, the lashes won’t last.
2. Humidity & Temperature Levels
Lash adhesive is sensitive to humidity and temperature, which directly affect drying time. For best results:
✅ Keep your lash room at 40–60% humidity
✅ Maintain a temperature of 18–24°C
✅ Use a hygrometer to monitor levels
✅ Adjust your adhesive based on conditions
If humidity is too low, adhesive may take too long to dry, leading to weak bonds. If it’s too high, it may dry too quickly, causing poor attachment.
3. Client Aftercare
No matter how perfect your application is, clients need to follow proper aftercare to maintain retention. Educate them on these key points:
✅ Avoid water and steam for the first 24 hours after application
✅ Use oil-free cleansers and makeup removers
✅ Brush lashes daily with a spoolie to keep them neat
✅ Avoid sleeping on their face to prevent lash twisting
✅ No picking or pulling! This can damage natural lashes
Providing a detailed aftercare card or sending a follow-up message can help reinforce these habits.
4. Natural Lash Cycle & Shedding
Each natural lash has a growth cycle consisting of three phases:
1️⃣ Anagen (Growth Phase) – Young lashes that are still growing
2️⃣ Catagen (Transition Phase) – Lashes stop growing but are still attached
3️⃣ Telogen (Shedding Phase) – Lashes naturally fall out to make way for new ones
Since we naturally lose 2–5 lashes per day, some shedding is completely normal. However, excessive loss may indicate issues like seasonal shedding or underlying health concerns.
