Hair Extensions

Hair extensions authority

Sach & Vogue manufactures approved extension families made to order — colour, length, weight and construction options subject to production confirmation. Supply status is assigned at product-family level. This page summarises verified methods only; it does not replace SKU-level specification on approved product pages.

Before ordering, read how fibre quality is defined beyond a single marketing label in our Hair Intelligence flagship (HI-001). Salon professionals may also review the professionals hub for journey eligibility and the manufacturing hub for production evidence and custom pathways.

Professional decision framework

Method selection should follow consultation, not catalogue browsing. Where two methods appear suitable, prefer the one that respects the weakest constraint — usually density, bond weight or maintenance capacity.

• Client hair density: Fine or sparse hair limits added weight. Micro keratin, narrow tape and Nanofilament may distribute load more evenly when bond size, spacing and the natural hair’s strength are assessed professionally — not every fine-haired client suits every low-weight format.
• Strand strength: Fragile or recently lightened hair may not tolerate heat fusion or mechanical stress. Match bond size to what natural hair can carry.
• Placement area: Temples and sides need smaller footprints. Crown work may accept wider tape or weft rows where parting allows.
• Required movement: Updos and ponytails need secure attachment with predictable swing. Bond direction must follow the style.
• Wear period: Semi-permanent methods suit clients who can maintain a regular salon schedule. Clip formats suit occasional wear or method trials.
• Maintenance capacity: Retaping, refusion and bead tightening need salon time and client compliance. Under-schedule maintenance increases shedding risk.
• Installation time: Full-head keratin may need multi-hour appointments. Clip-ins and pre-planned weft rows reduce chair time.
• Visibility requirements: Fine hair and sharp partings expose edges. Narrow tape, Butterfly folding and micro keratin reduce line visibility.
• Intended volume and length: Gram planning must match Draw Class and Ratio. State length, row architecture and piece count before quotation.
• Professional application competence: Each method has a skill floor. Stock only formats your team can install and maintain correctly.

Manufactured by us

Tape-In hair extensions

Construction

Double-sided adhesive tabs on machine-cut weft. Manufactured widths: 4 cm, 3 cm and 2 cm. Butterfly Tape folds from approximately 2 cm to approximately 1 cm for discreet side and fine-hair placement.

Typical professional use

Semi-permanent length and volume with predictable retape cycles. Full-head and partial-row services; often paired with keratin at the hairline for finer control.

Placement context

Sandwiched pairs below the part line — extension, natural section, extension. Narrow widths and Butterfly folding improve concealment at temples and above the ears.

Weight and distribution

Load spreads across the tab surface. Fine hair needs narrower tabs and fewer rows per level. Confirm gram totals per row when ordering.

Visibility

Correct colour, elevation and row depth hide lines under normal parting. Overtight sandwiching or scalp oils near the bond increase edge visibility.

Installation and maintenance

Install on clean sections with approved adhesive. Maintenance timing depends on natural-hair growth, attachment condition, density, aftercare and the professional’s inspection. Avoid heavy oils at the bond line.

Advantages

Moderate install time, flat profile, straightforward professional removal and strong colour matching across 141 standard shades.

Limitations

Heat near tabs weakens adhesion. Invisible/injection tape-in availability requires current product confirmation.

Ordering questions

Specify tab width, Butterfly requirement, length, colour code, Draw Class, Ratio and row count. State whether hair-only or full retape reorder.

Manufactured by us

Keratin bond extensions

Construction

Cured keratin bonds in Flat, U, V and I formats. Standard strands: 0.8–1.0 g. Micro keratin: 0.5–0.6 g. Nanofilament: 0.3 g micro keratin — a bond format, not a nano-ring product.

Typical professional use

Strand-level control for face framing, density correction and frequent parting. Flat tips suit wide sections; U/V/I profiles match different fusion angles.

Placement context

Bonds on isolated strands with controlled spacing. Direction follows natural fall. Hairline work needs lighter bonds and wider spacing.

Weight and distribution

Point load per natural strand. Total weight equals strand count × bond weight. Bond format should match natural-hair strength, density and strand loading as assessed professionally — micro keratin and Nanofilament may be appropriate where standard bonds would overload individual strands.

Visibility

Correctly sized, colour-matched bonds hide at normal viewing distance. Oversized bonds on fine hair show at the part line.

Installation and maintenance

Professional fusion with controlled heat. Maintenance timing depends on natural-hair growth, attachment condition, density, aftercare and the professional’s inspection. Document bond maps for consistent refits.

Advantages

Maximum styling freedom, natural movement and format choice to match section geometry.

Limitations

Skill-intensive. Incorrect temperature damages natural hair. Standard bonds suit fewer fine-density clients without reduced strand count.

Ordering questions

State tip format, weight tier, colour, length, gram or strand count and Draw Class. Note if full head, refill or corrective work.

Manufactured by us

Micro capsule extensions

Construction

Reduced-diameter keratin bonds at 0.5–0.6 g, plus Nanofilament at 0.3 g. Keratin fusion products — not nano-ring or mechanical ring systems.

Typical professional use

Fine-haired clients, front sections, low-density recovery and visible partings where standard keratin reads too heavy.

Placement context

Tighter spacing than standard keratin because point load is lower. Density rules still apply — more bonds cannot compensate for weak natural strands.

Weight and distribution

More attachment points per gram with lower load each. Calculate head totals conservatively; micro formats increase labour per gram delivered.

Visibility

Smaller bonds reduce scalp shadow on fine or light hair. Bond colour selection remains as critical as size.

Installation and maintenance

Same fusion discipline as keratin with adjusted heat for smaller bonds. Nanofilament suitability for fine hair depends on strand strength, density and professional assessment — not on bond size alone.

Advantages

Keratin-quality movement where lighter bond formats are confirmed suitable after professional assessment. Nanofilament may extend hairline options without changing attachment category when strand strength and density support it.

Limitations

Higher strand count increases chair time. Do not confuse with nano-ring products — those are not supplied.

Ordering questions

Confirm micro (0.5–0.6 g) or Nanofilament (0.3 g), tip format, colour, length and target strand count. State client density class.

Manufactured by us

Micro-ring extensions

Construction

Sach & Vogue manufactures the I-Tip extension hair used in Micro Ring / I-Tip applications. Attachment uses mechanical rings or beads on compressed natural hair — professional consumables, not manufactured in-house. Nano-ring and nano-tip extensions are separate categories: not supplied and not manufactured by us.

Typical professional use

Clients avoiding adhesive or heat attachment. Moderate density addition and repositionable work where refusion is undesirable.

Placement context

Rings on compressed natural strands with extension threaded through. Bead size must match hair texture — coarse and fine hair need different dimensions.

Weight and distribution

Load transfers through the anchor strand. Distribute rings across levels; concentrated horizons cause slippage or breakage.

Visibility

Bead colour and size affect part-line appearance. Match finish to root colour. Overtightening damages hair without improving concealment.

Installation and maintenance

Install with approved pliers and ring sizes sourced as professional consumables. Maintenance timing depends on natural-hair growth, attachment condition, density, aftercare and the professional’s inspection. Removal releases rings without solvent.

Advantages

No fusion heat at the bond, repositionable during maintenance and straightforward method changes at removal.

Limitations

Mechanical stress if over-weighted. Nano-ring/nano-tip products are outside scope. Bead sizing adds consumable complexity.

Ordering questions

Specify colour, length, gram total, Draw Class and pre-tipped versus weft format. Confirm local bead supply or separate sourcing needs.

Manufactured by us

Machine weft hair

Construction

Industrial sewn top edge; cut edges require sealing. Machine weft, Butterfly Weft and Genius Weft are approved machine-weft families manufactured by Sach & Vogue. Butterfly Weft uses textile tulle with hair sewn in opposing directions — not a PU panel with pre-punched holes. Three-piece Butterfly planning may use 28 cm, 20 cm and 12 cm widths. Hand-tied weft is not offered.

Typical professional use

Highest gram efficiency per session — full-head volume, length jumps and sew-in applications. Butterfly Weft supports faster panel coverage with controlled seam flip.

Placement context

Anchored to braided tracks, micro-ring rows or thread channels. Lower rows for length; higher rows for crown volume.

Weight and distribution

Continuous row spreads load along the track. Heavy single wefts overload narrow braids. Butterfly three-piece planning distributes bulk across panel widths.

Visibility

Weft tops must sit below the client’s part. Opposing-direction sewing helps Butterfly panels fold with natural movement.

Installation and maintenance

Seal cut edges before install. Adjust sew-in tension as hair grows. Maintenance timing depends on natural-hair growth, attachment condition, density, aftercare and the professional’s inspection.

Advantages

Cost-efficient gram delivery, strong for dramatic transformations, manufactured with colour, length, texture and Draw Class options.

Limitations

Demands braiding or sewing competence; harsh partings expose poor row planning. Hand-tied weft is not offered. Genius Weft specifications are confirmed per approved SKU — do not assume interchangeability with every sew-in technique.

Ordering questions

State standard weft, Butterfly Weft or Genius Weft, panel widths, colour, length, grams, Ratio and install technique (sew-in, beaded, etc.).

Manufactured by us

Clip-in extension sets

Construction

Machine-weft hair with sewn pressure clips. Manufactured in 1-, 3-, 5- and 7-piece configurations.

Typical professional use

Retail clients, event styling, method trials and salon add-on sales. Professionals may trim and blend during styling appointments.

Placement context

Clips on horizontal sections below the part. Largest wefts at the occipital area; smaller pieces frame the sides.

Weight and distribution

Weight concentrates at clip points. Seven-piece sets on fine hair may overload individual clips — recommend fewer pieces or lighter wefts.

Visibility

Thin anchor sections or colour mismatch expose clip bases. Slight backcombing improves grip without showing hardware.

Installation and maintenance

Client-applied for daily or occasional wear. No fusion cycle. Periodic clip tension adjustment; monitor shedding as with any extension hair.

Advantages

No semi-permanent commitment, accessible price point and useful upsell toward tape or keratin after trial.

Limitations

Clips shift during sport or sleep if worn incorrectly. Not full integration for active lifestyles.

Ordering questions

Specify piece count, colour, length, Draw Class and retail versus salon-blended finish.

Manufactured by us

U-Clip / U-Part extensions

Construction

Wefted hair with clip architecture leaving a U-shaped natural crown exposed. Made to order with colour, length, texture and approved density options.

Typical professional use

Clients wanting a visible natural part with added volume — common in textured and curly matching workflows.

Placement context

Natural crown must be dense enough to blend. Clip rows sit around the leave-out; curl pattern and colour dimension drive the blend.

Weight and distribution

Most weight sits off the part line. Balance pieces so clips do not pull forward on fine front hair.

Visibility

The part reveal is intentional. Poor leave-out density exposes the transition immediately.

Installation and maintenance

Client or stylist placement each wear cycle. Clip adjustment, detangling at the leave-out boundary and periodic set refresh.

Advantages

Faster than full sew-in, natural part aesthetics without crown fusion, strong retail story for textured-hair clients.

Limitations

Unsuitable without adequate crown density. High-tension updos may need additional pinning of leave-out hair.

Ordering questions

Confirm U-Clip versus U-Part, colour match to leave-out, length, texture and centre versus side part bias.

Manufactured by us

Ponytails and bangs

Construction

Ponytails with wrap-around or band attachment by specification. Clip-in bangs and fringes — short, long and curtain shapes — use a clipped weft row at the front hairline.

Typical professional use

Event styling, editorial work and instant nape length without full-head install. Bangs for fringe trials without cutting natural hair.

Placement context

Ponytails anchor at the client’s natural pony position. Curtain bangs need centre or off-centre parting to read correctly.

Weight and distribution

Ponytail weight hangs from one anchor — the natural pony must tolerate added grams. Lighter Draw Class suits fine hair.

Visibility

Wrap constructions must hide the client’s own pony tail. Sparse front hair may show bang clip bases.

Installation and maintenance

Mostly client-applied. Wash schedules follow standard extension aftercare; bangs need daily placement and removal.

Advantages

Low commitment, strong gift and impulse retail potential, useful salon add-on without a full consultation block.

Limitations

Single-point anchoring limits suitability for very fine hair. Bangs require separate planning from semi-permanent methods.

Ordering questions

Specify ponytail attachment type, length, colour, texture and gram weight. For bangs, state shape and clip count.

Manufactured by us

Textured hair extensions

Construction

Texture is an attribute on an approved manufactured family — wave, body or curl pattern subject to production confirmation. Not a blanket claim across every construction.

Typical professional use

Clients with natural curl or wave needing matched integration without daily heat styling. Available on tape, keratin, weft and clip where feasibility is confirmed.

Placement context

Match pattern calibre to natural texture. Consider shrinkage in length planning for tighter curl types.

Weight and distribution

Curly hair appears fuller per gram — reduce row count versus straight hair at the same headline weight. Ratio and Draw Class still govern density.

Visibility

Texture mismatch reads before attachment type fails. Root depth and highlight placement must align with natural variation.

Installation and maintenance

Follow the base method’s rules. Hydration-focused aftercare; bond lines and beads still avoid heavy oil saturation.

Advantages

Less daily styling for textured-hair clients and authentic movement in curly integration services.

Limitations

Custom texture requires feasibility review — not every pattern exists on every method or length.

Ordering questions

State base method, texture reference, colour, length, grams and client processing history for match approval.

141 standard colours

HairExtensionsTR works within a 141-shade colour architecture. Factory-coloured finished products are processed hair in the chemical-history sense even when production began with virgin raw material. See the quality framework (HI-001) before specifying colour on trade orders.

Standard shades cover solid tones, rooted effects and common dimensional blends. Custom colour may be discussed — feasibility, lead time and minimums are confirmed at quotation. We do not promise approval for every request. Orders should include shade code, root or highlight specification and match reference.

Custom production

Custom production and private-label pathways are available for approved manufactured families subject to specification review, MOQ and lead-time rules at quotation. Options include colour, length, weight, Draw Class, Ratio, texture and approved construction variants — always tied to a verified base method.

Private-label clients should supply brand guidelines and packaging requirements before sampling. Review the manufacturing hub for evidence standards. Nano-ring and invisible/injection tape-in require current product confirmation before entering a custom-production quotation.

Frequently asked questions

What is the difference between micro capsule, Nanofilament and nano-ring extensions?

Micro capsule and Nanofilament are keratin fusion formats at 0.5–0.6 g and 0.3 g respectively — attached by heat fusion, not mechanical rings. Nano-ring and nano-tip extensions are a separate category that we do not supply or manufacture.

Can I order invisible or injection tape-in?

Availability requires current product confirmation. Standard and micro tape widths — including Butterfly Tape — are the documented manufactured formats. Do not assume invisible/injection status from category labels alone.

Do you manufacture hand-tied or genius weft?

Machine weft — including Butterfly Weft with textile tulle and Genius Weft — is manufactured by us. Hand-tied weft is not offered. Construction details for each weft family are confirmed per approved SKU.

How should I choose between tape-in and keratin for fine hair?

Compare total weight and point load against natural-hair strength, density and strand loading. Narrow tape or folded Butterfly may spread load across a tab where professional assessment supports it; micro keratin and Nanofilament may suit strand work when density and strand strength allow. Standard 0.8–1.0 g bonds require careful strand-count planning on fine-density clients.

Are all 141 colours available on every method?

Not automatically. Availability is confirmed per method, length and production run. Custom colour requests require feasibility review and may carry different MOQ or lead time.

What should a professional enquiry include?

Method, construction variant, colour code, length, gram or strand count, Draw Class, Ratio, journey type and target install date. Incomplete specifications delay quotation.

Professional consultation

Specification should precede purchase: chemical status, direction, Ratio, Draw Class and fitness for the intended method. Read HI-001 before ordering trade quantities.

Salon teams new to a method should align training with stocked formats. The Application Academy covers approved methods confirmed during booking. See the manufacturing hub and professionals hub for production evidence and trade pathways.
