Hair color services on virgin hair should typically be performed every 4 to 8 weeks. This time frame is optimal for maintaining vibrant color while minimizing damage. Virgin hair, which is hair that has not been previously colored, reacts well to hair dye, allowing for even absorption and lasting results.

If color is applied too frequently, such as every 2 to 4 weeks, it can lead to potential damage since the cuticle layer of the hair may not have enough time to recover and repair itself. Over-processing can weaken the strands and lead to issues like brittleness or breakage. On the other end of the spectrum, waiting 8 to 12 weeks or just once a year could result in significant fading, uneven color, or visible roots, detracting from the overall appearance and effectiveness of the color.

The 4 to 8-week interval allows clients to maintain beautiful, fresh color while ensuring the health of their hair.
