How Quasi Colors Work:
* Deposit-Only (Mostly): Quasi colors primarily deposit color onto the hair shaft. They don't contain ammonia (or very low levels of it) or a high concentration of peroxide, which are needed to significantly lift or lighten the natural hair color.
* Minimal Cuticle Opening: Unlike permanent colors that aggressively open the hair cuticle to allow color to penetrate deeply, quasi colors cause minimal cuticle swelling or opening. The color molecules are smaller and sit mainly on the surface and within the outer layers of the cuticle.
* Fade Over Time: Because the color isn't deeply embedded, quasi colors gradually fade with each wash, typically lasting around 6-8 weeks (or 24-28 shampoos).
Effects on Hair Structure:
* Less Damage: Due to the low or absent ammonia and low peroxide levels, quasi colors are less damaging to the hair compared to permanent colors. They don't cause significant structural changes to the hair fiber.
* Cuticle Integrity: The minimal cuticle opening helps preserve the hair's natural moisture and strength. The hair cuticle remains relatively intact, contributing to a smoother and healthier appearance.
* Less Porosity: Quasi colors don't significantly increase hair porosity (the hair's ability to absorb moisture).
* Temporary Change: Since the color fades, the effect on the hair's underlying structure is temporary. As the color washes out, the hair returns to its original state.
* Conditioning Benefits (Sometimes): Some quasi colors contain conditioning agents that can improve the hair's texture and shine temporarily.
Summary:
Quasi colors are a gentler option for coloring hair because they primarily deposit color without causing significant damage or structural changes. They are ideal for:
* Covering grays (blending rather than complete coverage)
* Adding tone or shine
* Refreshing existing color
* Trying out a new color without a long-term commitment
Important Considerations:
* Allergies: Always perform a patch test before applying any hair color product, even quasi colors, to check for allergic reactions.
* Hair Condition: While quasi colors are less damaging, they can still affect hair that is already damaged or weakened.
* Color Result: The final color result depends on the existing hair color and porosity. It's best to consult with a professional stylist for the best color choice and application technique.
