Overview

A lamellar gloss built on Japanese rice water does the work here, coating strands in the shower after shampoo. You massage it through lengths and ends, rinse it out, and follow with the matching Izumi Tonic serum if you want extra polish.

Shine and strength come from one rinse-out step, and the formula leaves out silicones, sulfates and parabens. That suits anyone who avoids silicone coatings yet wants glassy hair. The strength and shine numbers are brand claims, and the listing gives no testing details behind them.

Who it's for

People with weak lengths, split ends or dull hair who already shampoo regularly will use it most. Those wanting a styling cream or a leave-in should look elsewhere, since this one rinses out.

Pros and cons

Pros
  • Rinse-out step fits a normal shower routine
  • Free of silicones, sulfates and parabens
  • Aimed at breakage and split ends
  • Pairs with the Izumi Tonic serum
Cons
  • Strength and shine figures are unverified brand claims
  • Must be rinsed, not a leave-in
  • Item form listed as serum, which is confusing

Performance notes

Results depend on contact time with wet hair, since the gloss is massaged in and then rinsed away. The rice water and lamellar layer act on the hair surface, so concentrating it on damaged lengths and ends gives the most visible change in shine and detangling.
