The bottle is ours. The label is yours. The images show our standard packaging with a sample label.

The Sealing Gloss line is a professional acid sealing system for private label production, available in four intensities: balanced, disciplining, restructuring and intensive. Professional use, applied in the salon. We produce the formula, supply the packaging, create the label with your identity and handle the ANVISA notification. ANVISA is Brazil's health regulatory agency. Minimum order of 100 units per product.

Four levels. A product ladder the salon gets right away.

No two heads of hair are the same, and your customer's customer knows it. With all four intensities under one brand, the stylist picks by the result they want to deliver, without switching suppliers halfway. That is what turns a single product into a line.

Intensity 01

Balanced Sealing

Moderate Sealing

Balanced alignment system, for volume control with a natural look and movement.

You don't have to launch all four at once.

Many brands start with two intensities and expand the line when they reorder. The packaging and the label layout stay the same. Only the formula and the variant name on the label change.

What you are seeing is an example. Yours will look like you.

The bottles in the photos use our standard packaging with a demo label. In your production run, the brand, the product names, the colors and the label layout are defined by you, and our design team builds the layout around your identity.

Prefer another type of packaging? That works too: you bring yours, and we validate it technically before producing.

Which intensity for which hair

Hair profile Variant Sealing System
Voluminous, wants alignment with lightness and a natural look Balanced Moderate Keratin + conditioning
Voluminous, unruly and with frizz Disciplining Uniform Keratin + conditioning
Voluminous, unruly and chemically treated Restructuring Uniform + repair Acids + keratin + shea
Voluminous, unruly and chemically treated Intensive Intense (high performance) Acids + keratin + shea

The first two variants work with keratin and a conditioning system. The last two add lactic acid and tannic acid, which act on the structural reorganization of the fiber. That is what separates uniform sealing from intense sealing.

In custom production, we adjust performance and concentration to the audience your brand serves.

Ongoing support

One direct contact from briefing to delivery. No middleman, no waiting for an answer.

How it works

From first contact to the product in your hands

  1. Conversation and briefing

    We understand what you want to launch, who you sell to and in what volume. If sealing makes sense for your audience, we move ahead.

  2. Sample

    We produce and send you a sample to evaluate. If anything is not the way you pictured it, we adjust and send it again.

  3. Approval

    The order is only closed after you approve the sample. Nobody produces at scale in the dark.

  4. Production and delivery

    With the formula approved and the label defined, we go into production.

Questions about the Sealing Gloss line

Do I need a CNPJ to produce?

Yes, we sell to registered companies: a CNPJ, the Brazilian company tax ID, or the equivalent company registration in your country. If you don't have one yet, we show you the way. Several of our clients opened their company during the process and have their own brand on the market today.

Can I launch a single intensity?

You can. Plenty of brands start with one or two and expand later. The advantage of planning the full line from the start is that the packaging and the label layout stay the same.

Is the formula exclusive to my brand?

Formulas developed exclusively for your project follow specific exclusivity rules, set out in the contract. Formulas from our portfolio stay available to other clients.

Do you create the label, or do I have to bring it ready?

Both work. Our design team creates the label with your brand, or you bring the finished file and we validate it technically before production.

How much does it cost?

The price depends on the formula, the volume and the packaging you choose. Tell us what you want to launch and we send you a quote.

Does the product carry the Belzark brand on the label?

No. The bottles in the photos use a demo label. The product that leaves our factory carries your brand: name, colors and layout defined by you, with our design team handling the execution within regulatory requirements.

Do you make hair color?

We don't produce hair dye. We work with the technical complements of the coloring process (cream developers and bleaching powder), plus the treatment, sealing and care lines.
