Target colour still determines part of the processing route. Dark, blonde, rooted and dimensional directions require different starting-material and colour decisions, and demanding colours must be evaluated on the finished construction.
The main hair shaft of Fully Cuticle-Intact Remy does not undergo strong-acid cuticle removal. However, for some extension constructions that rely on adhesive attachment, including Tape-In, Genius Weft and other structures with bonded attachment ends, approximately 1–2 cm at the attachment end may receive localised treatment to improve bonding strength.
Prime Human Hair does not use silicone-oil finishing on Premium Remy, Cuticle Remy or Fully Cuticle-Intact Remy. The three grades are differentiated by raw-hair selection, cuticle retention and processing route rather than by a temporary silicone-oil surface finish.
