We tracked 18 lash studios across Makati for 6 months, measuring three objective metrics: 4-week retention rate (percentage of lashes remaining at 28 days), adverse reaction incidents, and whether the glue brand used was disclosed upon request.

Retention at 4 weeks is the most honest measure of a lash studio's quality. Any studio claiming "6-8 weeks" for standard lash sets is misleading you — industry standard for quality work is 40–60% remaining at 4 weeks without infill.

The Lash Lab Makati (Trust Score: 91) is the only studio in our tracked group that publishes retention data openly. Their 4-week average is 52% — above industry standard — and they offer a free infill patch within 72 hours of any issue. That's real accountability.

Sofía Lash Studio (Trust Score: 90) wins for Asian eye shapes. The technician customizes curl type, length, and weight distribution for monolid and hooded eyes — not a one-size template. Average retention per client data shows 5 weeks.

Adhesive safety is the elephant in the room. Two studios in our tracked group refused to disclose their glue brand. One listed "professional adhesive" without brand. This is a red flag — near your eyes, cyanoacrylate quality directly affects allergic reaction risk. LashQuick Express is one such studio.

What to always ask: (1) What glue brand do you use? (2) Do you offer a patch test? (3) What is your glue-to-lash ratio protocol? Any certified technician can answer these confidently. If they hesitate, find another studio.
