Hair care's biggest players dominate artificial intelligence search results with outsized visibility. The top five brands claim approximately 50 percent of all hair care mentions on ChatGPT, according to new research from Avenue Z reported by WWD Beauty.

This concentration reflects a broader pattern in how AI systems surface information. When consumers ask ChatGPT for hair care recommendations, they encounter the same established names repeatedly. The dominance tilts heavily toward brands with extensive online presence and historical content indexed into AI training datasets.

The finding raises questions about discovery for smaller and emerging hair care companies. Brands outside the top five face significant headwinds in reaching consumers through conversational AI interfaces. Traditional search engines like Google already favor established players, but AI search amplifies this effect by returning confident, consolidated recommendations rather than diverse options.

ChatGPT's recommendations reflect patterns in its training data. Larger brands with more published reviews, articles, and digital footprint naturally appear more frequently. The AI doesn't actively promote one brand over another, but the data itself creates an uneven playing field. Smaller labels struggle to achieve visibility regardless of product quality.

This matters for beauty retail strategy. As consumers increasingly rely on AI for shopping guidance, brand visibility on these platforms becomes as important as traditional advertising. The top five hair care brands benefit from compounding advantages. They appear first in AI recommendations, which drives consumer interest, which generates more content, which feeds back into AI training.

Avenue Z's research quantifies what many in the beauty industry suspected. The shift toward AI search creates new winners and losers. Brands not in the top tier face a harder path to consumer awareness. They must either invest in content creation and brand building to eventually reach critical mass for AI visibility, or find alternative channels like influencer partnerships and direct-to-consumer marketing to bypass the AI bottleneck entirely.

The data underscores how artificial intelligence doesn't eliminate marketing challenges
