Here's why:
* No Developer: Manic Panic does not require a developer (hydrogen peroxide) to open the hair cuticle. This means it primarily deposits color on the surface of the hair shaft rather than penetrating deeply and permanently altering the hair's natural pigment.
* Fades Over Time: Because the dye sits on the surface, it gradually washes out with each shampoo. The vibrancy and color intensity will diminish over time, eventually fading completely.
* Lasts a Limited Time: Typically, Manic Panic can last anywhere from a few weeks to a couple of months, depending on factors like:
* Hair Porosity: Porous hair tends to absorb more dye but also fades faster.
* Hair Care Routine: Frequent washing, harsh shampoos, and heat styling can accelerate fading.
* Color Intensity: Brighter, more intense shades often last longer than pastel or lighter colors.
* Initial Hair Color: Manic Panic works best on pre-lightened hair (bleached), as it provides a blank canvas for the color to adhere to. On darker hair, the color may be subtle or not visible at all.
In summary, Manic Panic is a fun and temporary way to experiment with vibrant hair colors without the long-term commitment of permanent dyes.
