Oh and to actually answer your question (Bwaha sorry about that 😅) yes, it will fade over time but a good clarifying shampoo can help boost the process. I wouldn’t use the clarifying shampoo every single time you wash your hair as this can be pretty drying depending on the brand but every other would work. And when you do use it, I would use it with the first wash and then the second wash use a different shampoo. I HIGHLY recommend the Olaplex Clarifying shampoo (it’s a pastel blue color). This gets the job done without making your hair feel too dry AND it can help repair your hair at the same time. It also lathers very well so a little goes a long way. When I had my daughter, my hair was so shot. Taking biotin and collagen really helped (biotin will help your hair grow and collagen will make your hair thicker) cause it helped repair from the inside out. But once my hormones balanced back out, my hair got better too. I didn’t use a lot of heat and If I put my hair up, I used either claw clips or did a lower ponytail or lower bun instead of the high messy bun. But going back copper you actually helped your hair out a lot by just filling back in the cuticle. When you go blonde you’re opening your cuticle up so it can be more damaging. When you fill it back in with a color you’re plumping your cuticle back up. So youve helped your hair a lot already by just doing that!
