Abstract: Processes and kits for permanent waving keratin fibers achieve durable shiny waves. The processes comprise treating fibers with a reducing composition, a non-reducing and non-oxidizing alkaline composition, optionally and acidic composition and finally an oxidizing composition, wherein, after processing the reducing composition, the fibers are rinsed off and the fibers are inserted into a curler having a tubular body with a first opening located at the first end and a second opening located at the second end and, wherein the curler is configured to allow keratin fiber streak to be inserted from the first opening toward the second opening and it is capable of being rolled up.

Abstract: The present invention provides a hair treatment method for curling a lock of hair (H) using a hair holder (1). The hair holder (1) includes a tubular body (2) which has an opening (21) located at a first end of the tubular body and an opening (22) located at a second end of the tubular body, and which is configured to allow a lock of hair (H) to be inserted from the opening (21) toward the opening (22) and to be capable of being rolled up.
