What we require from every piece we sell

The problem

An industry built on claims no one checks

The hair extension industry has no regulatory body, no certification standard, and no independent testing authority. The terms "virgin," "raw," "Remy," and "unprocessed" are marketing language, not regulated classifications. Any vendor can use them freely, regardless of what the hair has actually been through.

The most common practice in the industry is the acid bath: hair collected from multiple donors (sometimes from temple floors or drain collections) is dipped in acid to strip the cuticle layer entirely, eliminating the tangling that occurs when cuticles from different donors interlock. The stripped hair is then coated in silicone to simulate the smoothness that intact cuticles would naturally provide. This hair is sold as "100% virgin Remy" with no legal consequence.

The result is a market where the majority of hair sold as virgin has been chemically processed, where geographic labels ("Brazilian," "Peruvian," "Malaysian") describe marketed textures rather than actual origins, and where the consumer has no reliable way to verify what she is buying before she buys it.

We built by Dallo to be the opposite of this. Not by making bigger claims, but by making every claim verifiable.

Construction

Silk base, tinted for melanin-rich skin

Most wigs and hairpieces use HD lace as the base material. Lace is thin, lightweight, and can create a convincing hairline when applied correctly. But lace has a fundamental limitation: it was designed for light skin tones. On melanin-rich skin, even "HD" lace creates a visible contrast at the part line. The fabric reads as fabric, not as scalp.

Silk base is a different construction entirely. Instead of a mesh through which you can see the scalp, silk base uses a layered membrane where the hair knots are sandwiched between two layers of silk. The knots are hidden inside the material, and the surface presents a smooth, opaque finish that replicates the appearance of a real scalp rather than relying on the wearer's skin showing through.

Why we tint the membrane

Standard silk base comes in a beige or light pink tone, designed for Caucasian or East Asian skin. On dark skin, this creates the same mismatch problem as lace, just in a different way: the part line reads as too light.

Every by Dallo piece uses silk base tinted to medium or dark brown directly in the membrane. The part line matches the scalp tone of melanin-rich skin without makeup, without concealer, without the constant maintenance that lace requires. This is not an aftermarket modification. It is how the piece is constructed from the beginning.

Verification

Five tests we run on every batch

Claims mean nothing without verification. We test every batch of hair before it enters production, and we document the results. These are not proprietary secrets. They are standard tests that any consumer can replicate at home. We publish them because transparency is the only proof that survives scrutiny.

The Burn Test

Cut a single strand and hold it over a flame. Real human hair burns slowly with a smell of burning keratin (similar to feather or fingernail), and leaves a fine black ash that crumbles between your fingers. Synthetic fibers melt, curl into a hard plastic bead, and produce a chemical smell. Mixed hair (human hair blended with synthetic filler) shows mixed behavior. This test confirms the hair is 100% human, with no synthetic blending.

The Raw Coacervation Test

We film the raw hair being combed through before its first wash. If a silicone coating has been applied (the industry standard for masking damaged hair), the comb slides through with zero resistance and an artificial glossiness. Genuinely raw hair has a natural, slightly coarse feel when dry. The comb encounters the texture of real, uncoated cuticle. This is the visual proof that no silicone layer is hiding what the hair actually looks and feels like.

The Stretch and Snap Test

Pull a single curl taut and release it. Chemically treated hair has lost its internal protein bonds. It either breaks under tension, or stretches without returning to its original shape. Hair with intact structure snaps back immediately, the curl pattern reforming on its own. This tests the structural integrity of the hair at the protein level.

The 10-Second Motion Test

In a vertical video, the wearer shakes her head in every direction for ten seconds. No glue. No tape. No clips. The piece does not shift. This is not a property of adhesive. It is a property of fit. A piece built to the exact measurements of the wearer's head stays in place through movement because there is nowhere for it to go.

The Air-Dry Time-Lapse

After washing, we film the hair drying on a stand at room temperature. No heat. No blowdryer. No diffuser. Over the course of several hours, the natural curl pattern re-forms on its own. Steam-processed hair (sold as "virgin" because no chemicals are involved) gradually loses its set pattern and reverts to something different. Genuinely raw hair returns to the same texture every time, because that texture was never artificially imposed.

Origin

Cambodian hair, traceable to the source

Geographic labels in the hair industry are largely fictional. Most hair sold as "Brazilian," "Peruvian," or "Malaysian" is sourced from collection operations in China, India, or Southeast Asia, processed in factories, and labeled with whatever origin the market responds to. The label describes a marketed texture, not a place.

by Dallo hair is sourced in Cambodia and processed in Cambodia. The entire chain (collection, sorting, construction, quality control) happens within a single operation. There is no intermediary factory in a different country relabeling the product.

Why Cambodian hair

Cambodian hair has specific characteristics that make it exceptional as a raw material for wigs and extensions. It tends to be naturally thick with a strong, resilient cuticle that holds up over time. The natural texture ranges from straight to loosely wavy, with a body and density that many other origins cannot match without chemical enhancement. It holds curl patterns well, it responds to heat styling without losing its natural texture permanently, and it has a natural luster that does not require silicone coating to look healthy.

These properties matter because they determine how the hair performs after months of wear. Thin, fine hair (common in Indian and Chinese sourcing) requires more chemical reinforcement to achieve body and durability. Cambodian hair achieves these naturally.

Single-donor collection

Every by Dallo piece uses hair from a single donor or a small, matched group. This means the cuticles are naturally aligned (they all grew in the same direction on the same head), the texture is naturally consistent, and there is no need for the acid bath that multi-donor hair requires to prevent tangling.

Single-donor collection is slower, more expensive, and produces smaller batches. It is also the only way to sell hair that is genuinely raw, genuinely Remy, and genuinely unprocessed, because the hair does not need to be chemically modified to function as a product.

Health

Designed for sensitive scalps

A significant number of women wearing wigs and extensions experience scalp problems: itching, irritation, contact dermatitis, and in severe cases, traction alopecia (permanent hair loss caused by sustained tension on the hair follicles). These are not inevitable side effects of wearing a wig. They are the result of specific, identifiable causes.

Chemical irritants

Acid-bathed, silicone-coated hair introduces chemical residues in direct contact with the scalp. Many women who believe they are "allergic to wigs" are actually reacting to the chemicals in the hair, not to the wig itself. Raw, unprocessed hair contains no chemical additives. It sits against the scalp the way your own hair would.

Tension from poor fit

Standard wigs come in Small, Medium, and Large. A piece that is too tight creates constant pulling on the hairline, particularly around the temples and edges. Over time, this tension damages the follicles and causes traction alopecia. A piece built to the wearer's exact measurements distributes weight evenly and creates zero tension at the margins.

Adhesive damage

Glue, tape, and adhesive-based attachment methods create a seal against the scalp that traps heat and moisture, blocks airflow, and can cause chemical burns or allergic reactions over time. A custom-fit piece does not require adhesive. It stays in place through precision of construction, not through chemical bonding to the skin.

by Dallo pieces are designed to be scalp-friendly by construction: raw hair with no chemical residue, custom fit with no tension, and secure hold with no adhesive. This is not a marketing claim. It is a direct consequence of how the pieces are built.

Fit

Built to your head, not to a size chart

Every head is different. The circumference, the shape of the crown, the position of the temples, the contour of the nape. Standard sizing (Small, Medium, Large) accommodates the average. It does not accommodate you.

Every by Dallo piece is constructed from a set of precise measurements taken by the wearer at home using our video guide. These measurements define the cap construction: where the piece sits, how weight is distributed, where the hairline begins and ends, and how the edges taper.

The result is a piece that stays in place through fit, not through force. No glue. No tape. No clips pulling at the hairline. The piece holds because it was made for the specific geometry of the wearer's head. The 10-Second Motion Test is the proof: shake your head in every direction, and the piece does not move.

This level of fit is not available through off-the-shelf sizing. It requires individual construction, which is why every by Dallo piece is made to order with a 4 to 6 week production time. The wait is the cost of precision.
