As the cost of spectroscopic devices drops, especially in the region covered by silicon-based detectors (visible to ~1050nm), we are starting to see devices embedded in consumer products developed by major manufacturers.
Three recent examples are:
Bosch X-Spect: https://www.home-connect.com/gb/en/connected-household/x-spect
Henkel SalonLab: http://salonlab.bplusd-interactive.de/
Procter & Gamble Opté™: https://www.opteskin.com/ and https://www.prnewswire.com/news-releases/pg-ventures-to-showcase-the-opte-precision-skincare-system-at-ces-2019-300772856.html
This is a fast-moving field today!
