  ABSTRACT: Hair coloring is widely used by women and men either to change their natural hair color or to delay the onset of gray hair. Oxidative dyes may damage the hair, since chemical and physical procedures are involved to alter the structure hair and consequently, alterations in its mechanical and of surface properties. One benefit of hair conditioners is to prevent flyaway hair, make the hair “shine”, and protect the hair from further damage. In this research we analyzed the hair protective effect conditioner agents Argania spinosa kernel oil and/or Theobroma grandiflorum seed butter in hair care on Caucasian hair post treatment with hair dye. The hairs were submitted by quantifying protein loss. The samples were classified as: hair untreated (I); hair treated with a commercial oxidative ultra-blond hair dye (II); hair post treatment II and F1: Base hair care formulation (III), hair post treatment II and F2: Base hair care formulation containing 1.0% (w/w) Argania spinosa kernel oil (IV), hair post treatment II and F3: Base hair care formulation containing 1.0% (w/w) Theobroma grandiflorum seed butter (V) and hair post treatment II and F4: Base hair care formulation containing 0.5% (w/w) Argania spinosa kernel oil and 0.5% (w/w) Theobroma grandiflorum seed butter (VI). For the protein loss, the results were: IIA = IIIA > IB = IVB = VB = VIB. Results classified with different letters present statistically significant differents, for α = 5, p ≤ 0.05, n = 6. Based on the results, the incorporation of conditioners agents Argania spinosa kernel oil and/or Theobroma grandiflorum seed butter in base hair care formulation applied in Caucasian hair post treatment with hair dye decreased the damage caused to hair by the coloring process.
