How to care for your lash extensions to make them last longer

Eyelash extensions are a significant beauty investment. However, without rigorous maintenance, this beautiful look can quickly deteriorate. Natural lashes lose between 2 and 5 lashes per day in their normal cycle. Consequently, extensions start to fall out visibly after only 2 weeks without proper care. The goal of this guide is to help you maximize their lifespan up to 3 to 4 weeks, while preserving the health of your natural lashes. By following a few simple rules from the moment they are applied and adopting an appropriate daily routine, you will fully recoup your investment and maintain a radiant look between each refill session.

The first 48 hours after application: a crucial period

The adhesive used to attach your extensions undergoes a polymerization process: it transforms from a liquid state to a solid resin. Understanding this transformation is fundamental to ensuring optimal adhesion. Within the first 4 hours, the adhesive reaches 90% of its stability, but complete polymerization only occurs between 12 and 24 hours. Finally, total crystallization is achieved after 48 hours. During this critical window, any exposure to water, steam, or humidity can permanently compromise retention.

Avoid water and humidity

During the first 48 hours, avoid showers, hammams, saunas, swimming pools, and aquagym. Water vapor softens the adhesive during crystallization and significantly reduces adhesion. Also, avoid movies or emotional situations that could make you cry. Polymerization requires stable conditions to ensure the durable attachment of the bonding points.

Limit eye makeup

Refrain from applying eyeliner, eyeshadow, or mascara during the 48 hours following application. The pigments contained in these products accumulate at the bonding points and can interfere with the drying of the adhesive. Waterproof makeup particles are particularly problematic, as their subsequent removal will require aggressive products incompatible with your extensions.

Daily routines to prolong retention

The longevity of your extensions relies on true teamwork: the technician applies quality extensions, but your daily maintenance determines their durability. Adopting a few simple actions helps maintain the necessary impeccable hygiene and prevents the accumulation of sebum, dust, and bacteria.

Clean your extensions twice a week

Regular cleaning with an eyelash shampoo enriched with keratin and provitamin B5, or an appropriate cleansing foam, is essential. You can also use Marseille soap or donkey milk. Apply the product with a shampoo brush or a silicone brush like the Master Brush, using gentle movements. This cleaning at least twice a week removes impurities that weaken adhesion. For a complete routine, consult our eyelash care routine guide.

• Prefer specific shampoos for extensions
• Apply with a clean brush or silicone brush
• Rinse gently with lukewarm water
• Pat dry with a clean towel

Brush your lashes daily

Use disposable wands or a perfectly clean mini mascara brush. Always brush from the root to the tip, only when lashes are dry. Wet lashes are heavier and more fragile, increasing the risk of premature shedding. This daily brushing helps to discipline, detangle, and arrange your extensions in a harmonious fan. Clean your brush after each use and store it in a clean case.

Appropriate makeup removal

To remove makeup from your face without damaging your extensions, prefer a no-rinse micellar water, ideally based on orange blossom. Apply it with lint-free foam-tipped swabs or cotton buds, proceeding with caution. Never use classic cotton wool, whose fibers can catch on extensions. Absolutely prohibit oily removers, biphasic solutions, cleansing milks, and all vegetable oils (jojoba, coconut).

• No-rinse micellar water only
• Foam-tipped swabs or cotton buds sparingly
• No oily or biphasic removers

Products and practices to absolutely avoid

Certain products and actions drastically alter the retention of your extensions. Knowing these prohibitions helps you avoid common mistakes responsible for premature shedding.

Fats and creams

Ban all fatty substances from 3 days before application and for the entire duration of your extensions. Oils, rich fatty serums, and rich eye creams alter adhesion by gradually dissolving the adhesive. Be particularly careful when applying your face creams: avoid the periocular area to ensure optimal retention.

• No vegetable oil on the eye contour
• No rich fatty serums
• Light eye creams only

Mascara and waterproof makeup

Mascara weighs down extensions, bothers the eyelid, and damages the structure of synthetic lashes. Glitter eyeshadows often contain fatty substances that impair adhesion. As for waterproof makeup, it requires aggressive removers incompatible with extensions. Prefer a natural look or limit yourself to light eyelid makeup.

Eyelash curler and heat

An eyelash curler mechanically pulls out and breaks extensions. Also avoid directing a hairdryer near your eyes during blow-drying, thermal shocks, and sudden temperature changes. Extensions already have a defined curl that does not require any additional device.

• No mechanical eyelash curlers
• No hairdryer near the eyes
• Avoid hammam and sauna after the critical 48 hours

Lifestyle and eyelash extensions

Your lifestyle directly influences the lifespan of your extensions. A few simple adjustments can limit rubbing and excessive handling.

Sleep and pillowcases

Repeated rubbing of cotton against your extensions during the night causes premature shedding. Opt for silk pillowcases for optimal protection. This material significantly reduces friction and preserves the curl of your lashes.

Do not rub your eyes

Avoid rubbing your eyes, handling your extensions excessively, or pulling on them. These actions weaken the bonding points and lead to premature shedding of extensions, sometimes accompanied by your natural lashes.

Individual factors influencing retention

Some elements are beyond your control but deserve to be understood. The natural cycle of your lashes results in the loss of approximately 21 lashes per week, or 42 lashes over 2 weeks. This constant renewal explains why regular touch-ups are essential.

Hair growth cycle

The rate of natural eyelash growth and shedding varies among individuals. Some people have a faster hair growth cycle, which accelerates renewal. To better understand this phenomenon, consult our article on the eyelash life cycle.

Skin type and hormonal factors

Oily skin produces more sebum, which reduces extension retention. Medications, hormonal imbalances, and certain physiological periods (pregnancy, menopause) also affect adhesion. Adjust the frequency of your cleanings according to your skin type.

The importance of regular touch-ups

Never neglect your refill sessions scheduled every 3 to 4 weeks. Your natural lashes continuously grow, moving the extensions towards the tip. This unevenly distributed weight creates discomfort and accelerates shedding. During touch-ups, the technician removes misplaced extensions and reapplies them at the root for a harmonious result.

Optimizing the health of your natural lashes

Between applications, nourish your natural lashes with appropriate serums. Some oil-free formulas are compatible with extensions. The TOTHELASH serum strengthens and fortifies your lashes for optimal regrowth.
