What category does demi-permanent color fall under?

Demi-permanent color is classified as long-lasting because it is designed to provide color that can endure through multiple washes while not being as permanent as traditional permanent hair color. It typically penetrates the hair shaft to some extent, allowing it to last longer than temporary colors, which generally coat the hair and wash out quickly. Demi-permanent hair color usually lasts around 4 to 12 weeks, depending on the specific product and hair care practices, making it an effective choice for clients who want a more durable color that doesn't require the commitment of a permanent dye.

Understanding the characteristics of demi-permanent color is crucial for hairstylists, as it allows them to make informed decisions when recommending color services to clients seeking a balance between longevity and gentleness on the hair.
