GK Hair

GK Hair is an American professional hair care brand founded in 2007 and headquartered in Oakland Park, Florida [1]. It was started under the name Global Keratin by Van Tibolli, who developed the proprietary keratin protein blend that became the company's central ingredient [4]. The brand builds salon-oriented treatments, shampoos, conditioners and styling products around that blend, and it remains active, with a regularly updated blog and online storefronts across several regions.

The company presents itself as American by origin and headquarters, while its founder, Van Tibolli, is described as Brazilian-born — a detail the brand states on its own history page [4]. Both points come from GK Hair's own materials; the United States is given as the country of origin and the location of its headquarters.

According to GK Hair, Van Tibolli founded the company in 2007 after identifying a gap in the market for reliable, effective hair care [4]. He created a purified keratin protein blend, named Juvexin, which the company describes as an anti-aging protein blend optimized for the hair. The brand's first product, launched the same year, was a keratin taming treatment built around this ingredient.

Tibolli is named as the founder and chief executive, and the company's headquarters are listed at Oakland Park, Florida. The original name, Global Keratin, reflected the keratin-based treatments at the core of the early range.

The business launched in 2007 as Global Keratin and re-branded to GK Hair in 2011 [4]. The company says its range has since grown from the founding keratin treatment into a broader system of shampoos, conditioners, serums and styling products. GK Hair reports that its salon-professional treatments, styling tools and consumer products are sold in more than 70 countries [4], and it operates separate regional storefronts for markets including the United States, the United Kingdom, Canada, Australia and Europe.

GK Hair positions itself as a professional, salon-oriented brand. Its stated mission is to deliver healthy hair and to "create vibrance and confidence for all people" through its hair care systems, and it markets to both salons and end users [1]. The company's products are framed around hair health and repair rather than a particular aesthetic, with educational content on damage, breakage and maintenance forming a large part of its published material.

The brand's range centers on Juvexin, the keratin protein blend Tibolli developed at the company's founding. GK Hair describes Juvexin as a keratin anti-aging blend intended to restore hair toward a more youthful state and protect it from further damage. The company says it is "the first and only company to harness the beauty benefits of Juvexin", delivered to the hair in what it calls its natural state [2]. A later version, Juvexin V2, is described by the company as non-hydrolyzed and made up of both large and small molecules: the smaller molecules are said to penetrate the hair's cortex while the larger ones form a protective layer around the cuticle.

Signature products named by the company include The Best Hair Treatment (its keratin taming system), a moisturizing shampoo and conditioner, an argan oil serum, a deep conditioner treatment and a leave-in conditioner cream. Alongside keratin, GK Hair lists pea protein, quinoa protein and argan oil among its key ingredients. The company states that many of its shampoos and conditioners are sulfate-free and paraben-free [4], and it describes its formulations as gluten-free; it presents Juvexin's V2 plant-based sourcing, drawn from pea and quinoa, as suited to a vegan lifestyle [2]. GK Hair also describes its keratin approach as patented, though it does not publish the patent details [4].

GK Hair is an active brand. It maintains a frequently updated blog, with several posts published each week through mid-2026 — the most recent extracted entry is dated June 10, 2026 [3]. The company operates live e-commerce and regional storefronts across the United States, United Kingdom, Canada, Australia and Europe, consistent with its stated distribution in more than 70 countries.
