Description
Hedrin Kills Lice Shampoo is the most bath-time-friendly Hedrin treatment row because the official UK page frames it as a 5-minute shampoo routine rather than an overnight or long leave-in process. It makes the most sense for households that are happy to comb thoroughly after rinsing and then recheck a week later.
It is less attractive if you want a true no-comb route or if you are treating a child under 1 year.
