Over the past 12‑18 months the Scalp Health Tester industry trends have accelerated through a blend of strategic alliances, technology roll‑outs and regulatory shifts. In Q2 2023, DermTech partnered with biotech firm BioSense to embed real‑time microbiome sequencing into its handheld tester, expanding distribution to European salons. The same year, market leader ScalpMetrics acquired startup FollicleAI for $78 million, adding AI‑driven predictive analytics to its platform. In early 2024, Luminex unveiled a cloud‑connected device that combines optical spectroscopy with machine‑learning algorithms, promising diagnostic accuracy within seconds. The U.S. FDA’s revised “Cosmetic Device” classification, effective July 2023, lowered the clearance threshold, prompting several manufacturers to fast‑track product launches. Consumer demand has shifted toward at‑home diagnostics, driving e‑commerce sales up 42 % YoY, while enterprise clients prioritize bulk licensing for employee wellness programs. Finally, a $45 million Series C round led by HealthCap enabled a Singapore‑based startup to scale production and open a new R&D hub in Seoul.
