Casting Crème Gloss

Decent 3.3 / 5

This is a standard permanent hair dye formulation with a blend of oxidative dyes and a hydrogen peroxide developer. It incorporates several conditioning agents to help mitigate potential damage. However, the extensive list of fragrance components and the inherent nature of permanent hair dyes with their associated irritants and allergens necessitate careful consideration and patch testing, especially for individuals with sensitivities.

About this product

This product is a permanent hair dye, indicated by the presence of multiple oxidative dyes and a hydrogen peroxide developer. It also contains conditioning agents and emollients to mitigate potential damage during the coloring process.

Good signs
  • The formula includes a variety of conditioning agents and emollients such as cetearyl alcohol, glycerin, isopropyl myristate, sunflower seed oil, and shea butter, which can help to protect and moisturize hair during and after coloring.
  • Honey is included, which is known for its humectant and conditioning properties, potentially adding to the hair's moisture and shine.
  • Ascorbic acid and sodium metabisulfite are present as antioxidants, which can help to stabilize the dye formula and protect hair from oxidative stress.
Watch-outs
  • The product contains a significant number of fragrance ingredients (Parfum/Fragrance, Linalool, Cinnamyl Alcohol, Citronellol, Coumarin, Hexyl Cinnamal, Amyl Cinnamal, Dimethyl Phenethyl Acetate, Tetramethyl Acetyloctahydronaphthalenes), which are common sensitizers and can cause irritation or allergic reactions, especially for individuals with sensitive skin or fragrance allergies.
  • As a permanent hair dye, it contains several oxidative dye precursors (e.g., Toluene-2,5-Diamine, m-Aminophenol, p-Aminophenol, 2,4-Diaminophenoxyethanol HCl, N,N-Bis(2-Hydroxyethyl)-p-Phenylenediamine Sulfate) and hydrogen peroxide, which are known irritants and potential allergens. Patch testing is crucial before use.
  • Ethanolamine is used as an alkalizing agent, which can be less irritating than ammonia but still has the potential to cause irritation and dryness.
Best for
  • Individuals seeking to permanently change their hair color.
  • Those looking for a hair dye that includes some conditioning ingredients.
  • All hair types, but caution is advised for individuals with sensitive scalps or known allergies to hair dye ingredients.
How to use it
  • Always perform a patch test 48 hours before each use, even if you have previously used coloring products.
  • Follow all instructions carefully to minimize potential irritation and ensure desired results.
  • Avoid contact with eyes and skin.
