Lash Day Studio Siam is a shop in Eight Thonglor in Bangkok that does eyelash extensions, lifts, and eyebrow waxing and lamination. It offers black and brown extension lashes and adjusts natural and volume styles through consultation. Eyebrow lamination and eyelash lift and tint took about 1 hour 10 minutes, and bookings are made quickly through LINE. Eyelash lifts do not always lift as much as expected, and extension lash retention is sometimes short.
