Step 1

Hair Analysis

Pre Caution

Before you start the straightening process, be aware of the following things

  • Never combine cream and gel straighteners nor combine different strength

  • Read the direction carefully before proceeding with the procedure

  • Not following the direction can  result in hair breakage/over processing and/or skin irritation

  • Do not use product if your client has had an allergic reaction to thermal straighteners, perm solutions, coloring hair dye

Hair Analysis

  • Check the hair type, chemical treatment history, dryness and damage level.

  • The processing time will become shorter with repeated and/or compound chemical procedures.
