The flat hair series of false eyelashes has emerged as a game-changer in the beauty industry, favored for its unique flat fiber structure. Unlike traditional round fiber false eyelashes, flat hair lashes feature a flattened cross-section, which gives them a more natural appearance, lighter weight, and better adherence to the lash line.
Ideal for both daily makeup and professional beauty settings, this series caters to diverse needs—from subtle enhancement to dramatic looks. In this guide, we’ll delve into practical solutions for common issues, essential precautions, step-by-step operation processes, and strict quality control measures, providing comprehensive insights for users and B2B partners alike.
Even with high-quality flat hair false eyelashes, users may encounter occasional challenges. Below are targeted solutions for the most common issues to ensure optimal performance and user satisfaction.
One of the top concerns is false eyelashes failing to stay in place or slipping during wear. This issue often stems from improper glue application, mismatched glue types, or an unclean lash line.
Solutions:
Choose the right glue: Opt for latex-free, high-tack adhesives designed for flat hair lashes. These glues have a balanced viscosity—thick enough to hold the flat fibers but not too runny to avoid smudging. For sensitive skin, select hypoallergenic formulas (e.g., formaldehyde-free options).
Prep the lash line: Before application, wipe the upper lash line with a mild oil-free cleanser to remove makeup residue, oils, or sweat. This ensures the glue bonds directly to the skin.
Apply glue correctly: Apply a thin, even layer of glue along the lash band. Wait 30–60 seconds until the glue turns tacky (not wet) before applying—tacky glue creates a stronger initial bond with the flat band.
Flat hair lashes are designed for naturalness, but improper trimming or style selection can make them look fake.
Solutions:
Customize the length: Measure the lash against your eye shape before wear. Trim the outer or inner corners (never the lash fibers themselves) to fit the width of your eye. Flat fibers are more flexible, so trimming the band slightly shorter than the eye width prevents “overhang” that looks unnatural.
Match the lash style to eye shape: For almond eyes, choose winged flat lashes to enhance the lift; for round eyes, opt for lashes with gradual length (shorter inner corners, longer outer) to add dimension without overwhelming. Our flat hair series includes 8+ styles tailored to different eye shapes (see Table 1 for style recommendations).
Flat hair lashes are lightweight, but discomfort can occur due to poor fit or sensitivity to materials.
Solutions:
Adjust the lash band: If the band feels rigid, gently bend it back and forth between your fingers to soften it—this makes it conform better to the eye curve. Avoid overly tight bands; our flat hair series uses ultra-thin, flexible cotton bands to reduce pressure.
Test for sensitivity: Before first use, place a small piece of the lash band (or a drop of glue) on the inner elbow and wait 24 hours. If redness occurs, switch to hypoallergenic lash bands (we offer silk-based bands as an alternative) and fragrance-free glue.
To ensure safety, longevity, and optimal results, follow these precautions—critical for both end-users and beauty professionals.
Avoid reuse of single-use lashes: Our flat hair series includes both reusable (up to 15 times) and single-use options. Check the product label—single-use lashes are not designed for cleaning and may harbor bacteria after one use.
Inspect before use: Examine the lash band for loose fibers or cracks. Damaged bands can cause irritation or uneven application; discard any compromised lashes.
Keep away from water pre-application: Ensure the lash line and lashes are completely dry before applying glue—moisture weakens the glue’s bond, leading to slippage.
Avoid touching or pulling: Refrain from adjusting the lashes with fingers during wear, as this can transfer oils to the band and loosen the glue. If adjustment is needed, use clean tweezers.
Limit exposure to moisture: While flat hair lashes are water-resistant, prolonged contact with water (e.g., swimming, heavy rain) can weaken the glue. Remove them before such activities.
Do not apply mascara directly to flat lashes: Mascara can clump the flat fibers, making them stiff and hard to clean. If extra volume is needed, apply mascara to your natural lashes first, then apply the flat lashes.
Remove gently: Never pull the lashes off forcefully—this can damage natural lashes or the lash band. Use an oil-based makeup remover on a cotton pad; hold it against the lash line for 10–15 seconds to dissolve the glue, then peel the lashes off slowly.
Clean properly: For reusable lashes, use a soft brush (e.g., a spoolie) dipped in mild soapy water to gently brush away glue residue from the band. Avoid soaking the lashes—excess water can loosen the fiber attachment.
Store in a dry, cool place: Use the original lash case or a lash storage box with a lid to protect lashes from dust, humidity, and 挤压 (squeezing). Avoid storing near heat sources (e.g., hair dryers), as high temperatures can warp the flat fibers.
Whether you’re a beginner or a professional, following a clear operation process ensures seamless application and removal. Below is a detailed, easy-to-follow guide.
Gather tools: You’ll need flat hair lashes, lash glue, small scissors, tweezers, and an oil-free cleanser.
Clean the eye area: Use the cleanser to wipe the upper lash line and eyelids, removing any oils, makeup, or debris. Pat dry with a clean tissue.
Trim the lash band: Hold the lash against your eye, aligning the inner corner with your natural lash line. Mark the excess length at the outer corner, then trim the band (only the band, not the fibers) in a straight line. Test again to ensure a snug fit.
Apply glue to the band: Squeeze a small amount of glue onto a clean surface (e.g., a makeup palette). Use the tip of the lash band to pick up a thin, even layer of glue, ensuring the entire band is coated (pay extra attention to the inner and outer corners, as these are prone to lifting).
Wait for tackiness: Let the glue sit for 30–60 seconds. The glue is ready when it turns from white to clear/translucent and feels slightly sticky to the touch—this is when the bond is strongest.
Position the lash: Use tweezers to hold the lash by the center. Align the inner corner of the lash with your natural lash line (1–2mm from the inner eye to avoid irritation). Press gently to secure the inner corner, then adjust the middle and outer corner, pressing each section for 5–10 seconds to set the glue.
Blend with natural lashes: Use a clean spoolie to gently brush your natural lashes and the flat lashes together, ensuring they blend seamlessly.
Prepare remover: Pour a small amount of oil-based makeup remover onto a cotton pad (avoid alcohol-based removers, as they can dry out the flat fibers).
Loosen the glue: Hold the cotton pad against the closed eye, focusing on the lash line, for 10–15 seconds. This allows the remover to break down the glue.
Peel off the lash: Gently lift the outer corner of the lash with tweezers or your fingertips. If resistance is felt, apply more remover and wait a few seconds—never pull forcefully.
Clean and store: Follow the cleaning steps in the “Post-Wear Precautions” section, then place the lashes back in their storage case.
At [Brand Name], strict quality control (QC) is integral to our flat hair series. We adhere to international standards to ensure consistency, safety, and durability—critical for B2B partners seeking reliable products.
The foundation of high-quality flat hair lashes lies in premium raw materials. We source and inspect materials rigorously before production:
All materials are tested for harmful substances (e.g., lead, phthalates) per REACH and CPSC standards, ensuring compliance with global safety regulations.
During production, we implement multi-stage inspections to catch defects early:
Fiber attachment check: After fibers are attached to the band, inspectors use magnifying tools to ensure each fiber is securely bonded (no loose ends) and evenly spaced. Random samples are pulled to test fiber retention—applying gentle tension to ensure<1% fiber loss.
Band shaping inspection: After the band is cut and shaped, check for uniform length, smooth edges (no rough spots that could irritate skin), and proper flexibility. Bands that fail the bend test (cracking after 300 bends) are discarded.
Style consistency check: For each batch, compare 20+ lashes against a master sample to ensure consistent curl, length, and fiber density. Any deviation (e.g., uneven curl) results in batch rework.
Before packaging, all flat hair lashes undergo final testing:
Appearance inspection: Check for defects like frayed fibers, glue smudges, or discoloration. Only lashes with 0 visible defects pass.
Wear simulation test: Selected lashes are applied to mannequin heads and subjected to 8-hour “wear” (simulating skin oils and movement). After removal, they’re inspected for fiber loss, band damage, or shape distortion—only lashes with no visible changes pass.
Packaging check: Ensure packaging is sealed properly, includes clear instructions (in multiple languages for B2B markets), and is labeled with batch numbers for traceability.
