Tips-in hair extensions — also called keratin bond extensions or K-tips — are individual hair strands with one end encased in a keratin bond, melted onto natural hair using a fusion iron and applied section by section for seamless, natural-looking volume and length. Each strand weighs 10–15g and is engineered for even weight distribution across the scalp, making them one of the longest-lasting semi-permanent methods available: a professional K-tip installation holds 3–6 months per wear cycle.
At K-Hair Factory, every tips-in strand is cut from 100% single-donor raw Vietnamese hair — cuticle-aligned, unprocessed, and built for a 4–5+ year lifespan under professional care.
Keratin Bond Extension Types: I-Tip, Flat-Tip, and U-Tip
Tips-in extensions are defined by the shape of their keratin bond head, and each variant serves a different install profile. For wholesale buyers, stocking more than one type broadens the client base without requiring a different hair source — all three use the same raw Vietnamese hair strand, differing only in tip construction.
| Type | Bond Shape | Installation | Best For |
|---|---|---|---|
| I-Tip (cold fusion) | Straight cylinder | Threaded into a micro bead — no heat required | Fine or thin hair; sensitive scalp |
| Flat-Tip (hot fusion) | Flat, ribbon-shaped | Melted with fusion iron; lies flat against roots | Maximum discretion; thick or coarse hair |
| U-Tip (hot fusion) | U-shaped keratin cap | Melted and pressed around a small hair section | High-volume installs; durable bond needed |
Worth noting for salon stylists: always match section weight to extension weight during installation — attaching heavy bundles to fine or sparse strands increases traction on the follicle — a risk factor for traction alopecia over time. Prep natural hair with a clarifying shampoo before install to remove buildup and ensure the keratin bond adheres cleanly.

Tips-In Extension Pricing: Wholesale by Length
Keratin bond extensions sit at the higher end of the extension pricing spectrum — a reflection of their installation complexity and the salon expertise required. For wholesale buyers, that premium positions tips-in as a high-margin service tier with strong client retention: a properly-done install lasts 3–6 months, meaning clients return to the same stylist for maintenance rather than shopping around.
| Length | Keratin Bond Extensions (per 100g) | Hair Bulk |
|---|---|---|
| 8″–14″ | $24–$42 | $15–$35 |
| 16″–24″ | $40–$88 | $32–$80 |
| 26″ and above | $65–$120 | $55–$100 |

Why K-Hair’s Tips-In Extensions Stand Apart
The core advantage K-Hair holds over most wholesale competitors comes down to raw hair sourcing. Most vendors supply hair that lifts to #613 bright blonde — K-Hair’s single-donor raw Vietnamese hair bleaches to #60 Platinum Blonde, the highest bleachability standard in the market. For salon colorists, that extra lift range means no color-matching compromises.
- Bleach to #60 Platinum: Unprocessed, chemical-free sourcing means full lift without structural breakdown — a claim most mixed-donor suppliers cannot make.
- Consistent batch quality: 20+ dedicated QC executives verify sleekness, luster, and thickness on every production run — critical for salon buyers managing repeat client expectations.
- 4–5+ year lifespan: Raw hair retains structural integrity far longer than processed alternatives. Re-tipping with fresh keratin extends the strand’s usable life across multiple wear cycles.
- Full customization: Custom color blending, texture adjustments, and density specifications available — plus private labels and branded packaging for wholesale brand-building.
“When salon accounts switch to K-Hair’s keratin bond range, the feedback we hear most is about batch consistency. With raw Vietnamese hair, the texture, weight, and color response stay identical from order to order — which matters enormously when a client comes back for a restock six months later.” — Mrs. Cherry, Sales Manager, K-Hair Factory

FAQ: Wholesale Tips-In from K-Hair
Most common questions from first-time wholesale buyers — answered from the factory floor.
What types does K-Hair stock for wholesale?
K-Hair manufactures I-tips (cold fusion, beaded install), flat-tips (hot fusion, ribbon bond), and U-tips (hot fusion, keratin cap). All three use the same raw Vietnamese hair strand — buyers can stock multiple types from a single supplier without sourcing variation.
Are the extensions reusable?
Yes. I-tip strands are fully reusable — the bead is removed and the strand reinstalled at each move-up. Hot-fusion U-tips and flat-tips require re-tipping with fresh keratin using a professional fusion iron, after which the strand is reinstalled. The hair itself is not discarded after one wear cycle.
Can K-Hair extensions be colored or chemically treated?
Yes. K-Hair’s raw, cuticle-aligned Vietnamese hair processes exactly like natural hair — stylists can tone, deposit color, or darken freely. Perform chemical services before installation and avoid direct bleach contact with the keratin bond area to preserve structural integrity.
What is the MOQ and shipping timeline?
MOQ starts at 300g to unlock wholesale pricing. Standard orders ship via DHL or FedEx in 3–5 business days. Custom color or large distributor orders require 10–14 additional business days for production. Contact K-Hair’s team directly for tailored quotes and lead times.
