Based on the revised formula provided by the staff, this formulation is suitable for a hair serum, especially for dry hair.

The ingredients included are beneficial:

ProVitamin B5 (Panthenol): Helps moisturize and strengthen hair.
Pure Keratin and Hydrolyzed Silk Protein: These proteins help repair damaged hair and improve hair texture.
Silicone Quick-Cond (PEG-12 Dimethicone): This is a water-soluble silicone that provides conditioning, makes hair feel smooth (slip), and adds shine without being heavy. It's suitable for leave-on serums and helps address dryness.
Phenoxyethanol: Acts as a preservative.

The mixing method described by the staff is correct for this formula: simply mix all the ingredients together until you get a clear liquid. No heating or complex emulsification is needed.
