Color coatings with downstream features

This describes a method for coloring hair by first applying a pretreatment liquid that forms a base layer when partially dried. On top of this, two more liquids are applied to create the final colored coating. Optionally, the hair is first deeply cleaned using devices like ultrasound or electromagnetic frequencies, then treated with atmospheric plasma before the coloring process begins.

Why it matters: The two-year gap since filing is too short for the specialized equipment like atmospheric plasma generators, ultrasound, or electromagnetic frequency devices to have become significantly more accessible or cost-effective.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedAtmospheric plasma, ultrasound, EMF devices, chemical compositions
