PURC Keratin Hair Treatment (100ml) is a salon-style keratin system formulated with Brazilian keratin. This 100ml bottle is presented as a concentrated treatment for smoothing and straightening; one bottle is noted as suitable for short hair, with longer hair requiring additional product. The treatment lists an operating time of 20–40 minutes and an expected effect duration of 3–4 months.
Formulation options: Keratin listed in 0%, 5%, 8% and 12% concentrations (product listing refers to these as formalin levels).
Application steps noted: wash and fully dry hair, saturate sections, process 20–30 minutes depending on hair condition, dry again, then seal with a flat iron (instructions specify 450°F/230°C; lower heat for damaged hair).
Practical outcomes from features: when used with the recommended flat iron technique the product is intended for smoothing/straightening; following the stated aftercare (do not wash hair for 3 days) is part of the process described.
