Semi-permanent color works by depositing color onto the hair shaft, rather than penetrating the cortex like permanent color does. This means that the color will fade gradually over time, usually within 4-6 weeks. But don't worry, it won't just vanish into thin air - it'll leave your hair with a beautiful, subtle glow!
Now, you might be wondering, will it wash out completely? The answer is, it depends! If you use a high-quality semi-permanent color, it's likely to leave a slight residue on your hair, even after it's faded. But hey, that's not necessarily a bad thing - it can actually add depth and dimension to your locks!
Another thing to keep in mind is that hair porosity plays a big role in how well the color takes. If your hair is super porous, the color might wash out faster than you'd like. But if your hair is less porous, the color will last longer. So, it's all about finding the right balance for your hair type!
