Classic Lash Extensions in Midtown NYC

What Are Classic Lash Extensions?

Classic eyelash extensions are the foundational technique of the lash extension world: one individual extension is bonded to each single natural lash using a medical-grade, hypoallergenic adhesive. Unlike volume lash extensions that use fans of multiple lashes, classic extensions follow a strict 1:1 ratio — one extension per one natural lash.

At Iris Lash Studio in Midtown NYC, we use premium silk extensions in a range of lengths (8mm to 15mm), curls (J, B, C, D, and L curls), and thicknesses (0.10mm to 0.20mm). Every set is custom-mapped to your eye shape during your consultation, ensuring the result enhances your natural beauty perfectly.

Classic lash extensions are ideal for:

  • ✓Everyday, natural-looking enhancement
  • ✓First-time lash extension clients
  • ✓Clients who want a mascara-free morning routine
  • ✓Those with fuller natural lash lines
  • ✓Professional environments where subtle beauty is preferred

Classic Lash Extension Styles at Iris Lash Studio

Not all classic sets look the same. At our Midtown NYC studio, we customize every set based on:

Curl Types:

  • J Curl — Very natural, barely lifted. For those who want the most subtle enhancement possible.
  • B Curl — Slightly more lift. Natural but defined.
  • C Curl — Our most popular curl. Open-eye effect with a classic look. Flatters most eye shapes.
  • D Curl — Dramatic curl, wide-eye effect. More lifted than C.
  • L Curl — Designed for straight or downward-pointing lashes. Creates significant lift.

Eye Mapping Styles:

  • Natural/Open Eye — Uniform length across the lash line
  • Cat Eye — Longer toward outer corners for a sultry, elongated look
  • Doll Eye — Longest in the center for a wide, bright effect
  • Squirrel Eye — A blend of cat eye and natural styles

What to Expect at Your Classic Lash Appointment

Step 1: Consultation (10 minutes)

Your lash artist reviews your natural lashes, discusses your desired length and curl, and performs custom lash mapping.

Step 2: Cleansing (5 minutes)

Your natural lashes are gently cleansed with an oil-free lash primer to remove any trace of makeup or oil.

Step 3: Under-Eye Preparation (5 minutes)

Gel pads are placed under your eyes to protect your lower lashes and keep you comfortable throughout the appointment.

Step 4: Application (30–40 minutes)

Each individual extension is meticulously bonded to a single natural lash. You simply relax — most clients doze off!

Step 5: Final Styling & Review (10 minutes)

Your artist brushes and fans your new lashes, removing any gel residue, and you review the set together.

Total Duration: Approximately 60 minutes for a full set.

Classic Lash Extension Retention & Fills

With proper aftercare, your classic lash extensions will last 4–6 weeks, following your natural lash growth cycle. As your natural lashes shed, extensions shed with them. We recommend:

  • 2-Week FillIdeal for maintaining a full, fresh look. Best for clients who want their lashes looking perfect at all times.
  • 3-Week FillA great balance between maintenance and cost. Still achieves a full, polished look.
  • 4-Week FillSuitable for those with slower lash cycles and excellent aftercare habits.

Note: If more than 4 weeks have passed since your last fill, a full new set will be recommended to ensure quality results.
