Every few months a woman on a red carpet turns up with silver hair that looks like polished pewter, and the comments divide neatly into two camps: people saying how brave she is, and people quietly asking how on earth she got it to do that. The second question is the useful one. Because the glossy grey you admire is almost never luck — it's a combination of texture management, light, and a cut that lets the hair fall rather than frizz.
Grey hair genuinely behaves differently. It tends to be coarser and more wiry, the cuticle sits less smoothly, and with age the scalp produces less of the oil that used to travel down the strand and make it glint. Add a lifetime of heat styling and hard water and you have hair that scatters light instead of bouncing it back. Everything below is about putting that light back.
Shine is a surface, not a product
Hair looks shiny when the cuticle lies flat enough to reflect light in one direction. That's why a smooth blow-dry outshines the same hair air-dried in a rush, and why one rough-handled towel session can undo a good wash. So treat the surface with some care: squeeze water out rather than rubbing, use a microfibre towel or an old cotton T-shirt, and detangle with a wide-tooth comb from the ends upwards while there's still conditioner in.
Weekly, a proper conditioning mask left on for the full time — not the two minutes you've got — makes a visible difference on coarse grey. Rinse the final rinse cooler than feels pleasant. It's a small thing and it closes the cuticle.
