Two-Component Scalp Boosters: The HAIRREGEON Format

Korea's professional scalp-care segment is increasingly offering buyers not a ready-made serum, but a two-component system mixed right before use in the salon. One notable example of this format is the HAIRREGEON line, developed by the biotech company CK Regeon (the parent company behind the DermaRegeon brand, also known for its home-use HERIBON line). Below is a look at why the industry favors this way of delivering an active ingredient, and what it means for a wholesale order.

Why separate the active ingredient from the solvent

The line's flagship product, the PTD-DBM Hair Booster set, consists of two vials: Vial 1 contains a lyophilized (freeze-dried) powder of the active ingredient weighing 200 mg, and Vial 2 is a 5 ml solvent. One set is designed for a single use or for use over a course of treatment, and the package contains 5 such sets.

Lyophilization is a standard technique in the cosmetics and pharmaceutical industry for unstable active ingredients: in dry form, the substance is less prone to oxidation and degradation during storage and transport, and shelf life increases many times over compared to a ready-mixed water solution. Mixing the powder with the solvent right before applying it to the scalp gives the specialist confidence that the client is getting a freshly prepared formula, not a solution that may have lost activity over weeks or months in storage or on a shelf. This is a standard approach for any serum with unstable peptide or bioactive components — the two-component format by itself isn't a medical characteristic, it's an engineering solution for formula stability.

What's known about the active ingredient — and where the line is drawn

The active ingredient in the powder, PTD-DBM, is a peptide whose mechanism of action at the preclinical level (in vitro and in animal models) is described in Lee et al., published in the Journal of Investigative Dermatology in 2017: the authors describe competitive binding to the CXXC5 protein. This is cell- and animal-level research, not data from human clinical trials, and it's important for a buyer to communicate this distinction to distributors and salons in the target market — both in marketing materials and in instructions for the end specialist.

HAIRREGEON and products based on PTD-DBM are positioned by the manufacturer as cosmetic products for external scalp care within professional salon programs. Wording about treating alopecia, stopping hair loss, or clinically proven efficacy, along with any references to injectable, mesotherapy, or other intradermal use (including MTS protocols), doesn't match the product's status and shouldn't be used in promotion — this applies both to Teranova itself and to partners we help enter this market.

Economics of the professional segment for a buyer

The wholesale price is roughly $160 per package (5 sets) on FCA terms, with a minimum order of 5 packages. For the professional B2B segment, this is a fairly comfortable entry threshold: it allows testing the product in a local market without large inventory commitments, before scaling up an order for a salon network or distribution network.

The sales model in this segment differs fundamentally from mass market: the product isn't meant for a retail shelf but is sold through salons, trichology studios, and aesthetic clinics, where it's used over a course under a specialist's supervision. The high per-package price is offset by the fact that the end service at the salon generates its own margin for the partner, rather than competing on price with home care. Candidates for this order are professional beauty-industry distributors, trichology clinic chains, and salons with a scalp-therapy focus that already work with professional, not mass-market, cosmetics.

What to confirm before ordering

Before bringing the product into a specific market, it's worth closing a few practical questions: the regulatory status of the cosmetic product in the destination country (in some countries, professional scalp cosmetics are registered differently from mass retail), labeling and instruction-translation requirements, storage conditions for the lyophilized powder and the mixed solution, and whether salon staff need training on the application protocol. Teranova coordinates and supports this part of the work — from requesting current terms and batch details from the Korean side to arranging logistics and checking that documentation matches the target market's requirements — leaving final commercial and regulatory decisions to the partner.
