Treatroom Treatroom Signature

Most retail shampoos sold in the US come in 200-400ml bottles. The treatroom Signature line starts at 1077ml - more than triple the typical size. For households with multiple people, or for individuals who wash their hair frequently, a large-format bottle reduces how often you need to reorder, lowers the per-wash cost, and reduces packaging waste. The 1600ml Parfum Collection tier takes this further. These sizes are common in Korean salon-grade retail and are the reason the line is positioned as a salon-at-home option.

The Signature range is available in four scent variants: White Musk, Fruit Citrus, Baby Powder, and Cleansop. White Musk has the widest product range in the collection - it appears in both the standard Signature line and the Parfum Collection tier, and in both shampoo and treatment formats. Fruit Citrus is available as a shampoo. Baby Powder appears in both shampoo and treatment formats. Cleansop (a clean, fresh scent) is available as a treatment. Scent choice is the primary differentiator between many of the products in this line, as all are full-size salon-format products.

Several scents in the Signature line have both a shampoo and treatment counterpart. White Musk is the most complete: the Signature Shampoo White Mask Scent (1077ml), the White Musk Signature Treatment (1077ml), and the Parfum Collection Shampoo and Treatment in White Musk (1600ml each). Baby Powder also has both a shampoo and treatment. Using the same scent for shampoo and treatment keeps the fragrance consistent and allows the treatment to complement the shampoo step without mixing scent profiles.

The Signature Parfum Collection is sold in 1600ml - the largest size in the line - and is currently available in White Musk. It comes as a shampoo and as a treatment. The Parfum Collection name indicates a more fragrance-forward formulation compared to the standard Signature. For shoppers who want the most concentrated scent experience, or who prefer the largest possible bottle per purchase, the Parfum Collection is the right choice within the Signature range.

The Signature Large-capacity Parfum Shampoo White Musk 1077ml 4 pieces is the multi-pack option in the line. Four 1077ml bottles of the same White Musk shampoo in one order is suited for larger households, salons, or shoppers who want several months of stock at once. Buying the 4-piece set reduces reorder frequency significantly. It is the highest-volume single purchase available for the shampoo in this line.

Two scent variants exist only in one format within the current in-stock range. The Cleansop Signature Treatment (1077ml) is a treatment-only option - there is no matching Cleansop shampoo in the current collection. The Fruit Citrus Signature Shampoo (1077ml) is a shampoo-only option. These can be used standalone, or paired with a White Musk or Baby Powder counterpart from the same line if you prefer to mix scents across shampoo and treatment.

A typical shampoo use is 10-15ml per wash. A 1077ml bottle provides roughly 70-100 washes, or about 2-3 months for someone washing their hair daily. For two people sharing, it stretches to 1-1.5 months. The 1600ml Parfum Collection bottle extends this further. Because the per-wash cost is lower than small bottles of equivalent quality, large-format Korean hair care like the Signature line often saves money over a year compared to buying multiple smaller bottles.

The Signature Treatment products are conditioning treatments meant to follow shampoo. Treatments at this concentration and size suit hair that is dry, color-treated, or frequently heat-styled. Fine or oily hair types may find a full treatment too heavy for daily use - in that case, applying it only to the mid-lengths and ends, or using it 2-3 times per week rather than daily, gives conditioning without weighing the hair down. The large 1077ml size makes weekly rather than daily use very economical.
