b3 Brazilian Bond Builder

b3 Brazilian Bond Builder is a professional, salon-only haircare product made in the United States. It is an in-color bond-building treatment: a stylist mixes it directly into colour or lightener formulas to limit the damage that chemical services cause to the hair. The product is sold under the b3 name by Brazilian Professionals, LLC, and editorial coverage and the company's own materials describe it as the work of "the founders of Brazilian Blowout" [5]. The brand remains active; its official site is live in 2026 with a current product range and online ordering [1].

The company is based in North Hollywood, California, where its parent operates [7]. No founder names or a brand-stated founding year appear on the official site or in any quotable source; the earliest verifiable trace is a wave of beauty-press mentions in April and May 2015, which points to a market presence by mid-2015 [3].

b3 Brazilian Bond Builder is owned and distributed by Brazilian Professionals, LLC, which presents itself as the exclusive distributor of both the original Brazilian Blowout smoothing system and the b3 line [8]. The two products therefore share a corporate parent and, by the brand's account, the same originators. The company has not published a separate founding date for the b3 line, and no acquisitions are recorded for it.

The flagship product, b3 Brazilian Bond Builder, is a one-step additive intended to be combined with a colourist's existing formula without changing the developer or adding processing time. According to the company, it relies on "an anhydrous delivery system and specifically engineered co-polymer" — that is, a water-free carrier and a purpose-built polymer — to cut breakage while improving colour retention [2]. Because the formula is water-free, editorial coverage notes it does not dilute the developer, which the brand positions as an advantage during highlighting.

The company says the treatment is "clinically shown to penetrate the cortex of the hair" and to reattach bonds broken during colour services, working "at the cellular level" [2]. Third-party coverage adds detail on the mechanism: a 2016 comparison reported that b3 claims to realign three bond types — disulphide, salt and hydrogen bonds — and quoted the brand's global director of education describing how realigning the hair's structure helps seal the cuticle and lock in pigment [6]. This was a frequent point of contrast with Olaplex, which acts on disulphide bonds alone.

Beyond the core additive, the catalogue includes the b3 Demi Permanent Conditioner, the b3 Ionic Color Lock — described by the company as combining bond building with "ionic technology" — and a range of sulfate-free aftercare shampoos and conditioners for colour-treated hair and extensions.

b3 is positioned as a professional, salon-only tool rather than a consumer product, and the bulk of its range is sold to licensed stylists. Its stated appeal is convenience: editorial coverage quotes a stylist calling it a "good add-on treatment" that does not lengthen a client's salon visit because it is a single step folded into the colouring process. The intended user is the colour-treated client — particularly someone having highlights or lightening done — who wants to limit damage during the service.

The b3 product appeared during the mid-2010s wave of bond-building treatments led by Olaplex, and much of its press framed the two side by side. A June 2015 StyleCaster review by Rachel Adler, who described herself as a frequent hair-colour changer, rated b3 favourably against Olaplex for colour longevity and reduced breakage [5]. The same article reported, as an aside, that the product "saved Kim Kardashian's strands" after a brief bleaching [5]. The brand's own press page lists "as seen in" mentions across outlets including Allure, Vogue, Harper's Bazaar and InStyle between 2015 and 2019 [3].

In 2012, the maker of Brazilian Blowout settled a California lawsuit and agreed to change its labels to add a formaldehyde warning to its Brazilian Blowout smoothing solutions [9]. The matter concerned the smoothing-treatment line sold by the same parent company, not the b3 bond-building product, which is a separate item within the company's range.

The brand is active. Its official US site is fully operational in 2026, with a current product catalogue, e-commerce, a Spanish-language subdomain and a 2026 copyright notice [1]. The products are distributed through salons and authorised retailers, including in Nordic markets.
