How Much Does a Sew in Extension Cost? Hair Guide
A sew-in hair extension installation typically costs between $150 and $450 for the professional stylist installation labor, plus $150 to $600 for 2 to 3 bundles of 100% virgin human hair wefts, bringing total service costs between $300 and $1,050. The total investment depends heavily on your salon's location and stylist reputation, your desired hair length and density, and whether you choose a traditional leave-out sew-in, a lace closure sew-in, or an intricate 360 lace frontal installation. Because sew-in extensions are sewn onto a foundation of braided cornrows, they offer one of the most durable, heat-safe, and protective hair extension methods available.

Raw Hair Bundle Pricing: Virgin Human Hair Grades
A sew-in extension service begins with creating a secure structural cornrow braid foundation across the client's natural scalp. The stylist braids the client's natural hair into customized geometric patterns—such as beehive spirals, straight-back tracks, or zig-zag patterns—incorporating a breathable mesh weaving net over the braids to distribute tension evenly. Using curved blunt needles and heavy-duty nylon or polyester weaving thread, wefts of human hair are hand-sewn directly onto the braided anchors.
The leave-out technique represents the classic approach to sew-in styling. In a partial sew-in, a small rectangular or horseshoe-shaped section of the client's natural hair along the crown parting and hairline is left unbraided. Once the extension tracks are sewn in, the natural leave-out hair is flat-ironed or hot-combed over the top tracks to blend seamlessly. While this produces an undetectable look, clients must regularly apply thermal heat to their natural leave-out hair to match bone-straight or curled extension textures.
The quality, origin, and cuticle alignment of raw hair bundles dictate retail hair pricing and long-term reusability.
| Hair Length / Grade | Price per Single Bundle | Cost for 3 Bundles (Full Head) | Expected Reusable Lifespan | Hair Cuticle Quality |
|---|---|---|---|---|
| 12 to 14 Inches (Virgin Remy) | $50 - $80 / bundle | $150 - $240 | 9 to 12 Months | 100% Cuticle aligned; minimal shedding |
| 16 to 18 Inches (Virgin Remy) | $70 - $110 / bundle | $210 - $330 | 1 to 2 Years | Silky, full ends; bleaches to blonde safely |
| 20 to 24 Inches (Raw Temple Hair) | $95 - $150 / bundle | $285 - $450 | 2 to 3+ Years | Unprocessed single-donor hair; zero silicone wash |
| 26 to 30+ Inches (Raw Luxury) | $130 - $200 / bundle | $390 - $600+ | 2 to 3+ Years | Thick double-drawn ends; premium luxury density |
| HD Swiss Lace Closure / Frontal | $80 - $220 each | Added to bundle cost | 4 to 8 Months | Ultra-thin invisible lace; requires delicate care |
Scalp Foundation, Maintenance Schedules, and Hair Health
Lace closures and frontals eliminate the risk of heat damage to natural hair. A 4x4 or 5x5 lace closure features hundreds of individual hair strands hand-tied into a delicate sheer lace base that mimics the appearance of a natural human scalp. By installing a closure at the front hairline, 100% of the client's natural hair remains safely braided beneath the protective weave. Stylists charge an additional $50 to $100 for closures to bleach knots, pluck hairpins along the hairline for realism, and tint the lace to match the client's skin complexion.
Longevity and maintenance schedules are critical for scalp health. A professionally installed sew-in safely lasts between six and ten weeks. Leaving a sew-in installed beyond ten to twelve weeks risks severe hair matting, mold growth in damp braided cornrows, and traction alopecia as growing natural roots become entangled around thread loops. Salons offer maintenance appointments every three to four weeks ($60 to $120) to wash the tracks, sit under a hood dryer to thoroughly dry internal cornrows, and tighten loosened perimeter thread tracks.
Purchasing high-quality raw or virgin Remy human hair wefts represents a smart long-term investment. While synthetic or chemical-treated beauty supply hair costs under $100 for three packs, it tangles, mats, and sheds within three weeks and cannot withstand heat styling. In contrast, authentic virgin human hair bundles costing $250 to $450 can be washed, bleached, colored, re-used across three to five consecutive sew-in installations over two years, dramatically lowering your annualized hair budget.
How to Prepare and Budget for a Sew-In Installation
Follow these essential steps to purchase quality hair, prepare your natural hair, and maintain your sew-in weave.
Purchase 2 to 3 Bundles of Virgin Human Hair
Order 2 bundles for 12-14 inch lengths, 3 bundles for 16-22 inch lengths, or 4 bundles for lengths over 24 inches to ensure full density.
Shampoo, Deep Condition, and Blow Dry Natural Hair
Arrive at the salon with clean, product-free, deeply conditioned, and fully detangled hair so your stylist can braid cleanly.
Request a Breathable Protective Weaving Net
Ask your stylist to sew a fine mesh net over your cornrow foundation to alleviate direct thread tension on natural hair strands.
Verify Braid Tension Is Comfortable, Not Painful
Speak up immediately if braids or thread feel excessively tight around edges; painful braiding leads to headaches and traction hair loss.
Dry Braids Completely After Washing at Home
When washing your sew-in at home, sit under a hard-hat hooded dryer for at least 45 minutes to ensure cornrows dry thoroughly to prevent mildew.
