How does Lara Croft get her hair so shiny on PS4 and Xbox?

Lara Croft has lovely hair. Or, rather, she has lovely hair on the new generation of consoles (I'm talking about Tomb Raider: Definitive Edition) and on PC. On last-gen, said locks are comparatively lifeless. I can only assume this is because she's started using Tomb-otei: The shampoo for next-gen adventurers. So I made an advert for Tomb-otei, which you can see below. Sorry it isn't available in shops.
