Pure Color

When it comes to demi vs semi-permanent hair color, the two types of hair color formulas differ in how long they last and how they interact with the hair shaft.

• Semi-permanent hair color is a gentle, ammonia-free formula that coats the outside of the hair shaft without penetrating it. It does not contain peroxide, so it can’t lighten hair and typically lasts around 4 to 12 shampoos before gradually fading. This makes it ideal for adding a tint, enhancing natural color, or trying bold shades for a short time with minimal risk and no damage.

• Demi-permanent hair color contains low levels of peroxide. This allows the color to slightly penetrate the hair cuticle, resulting in longer-lasting results, lasting up to 12 to 24 washes. The presence of peroxide also enables demi-permanent color to blend grays more effectively and achieve deeper, richer tones, though it still can’t lighten hair like permanent dyes. Demi-permanent color is a great choice for those who want more durability than semi-permanent options, are looking for subtle color changes, or need to blend grays while maintaining a natural look.

Semi-permanent hair color typically lasts between 4 to 6 weeks, but the exact duration can vary based on several factors. The main influences are your hair type, how often you wash your hair, and the products you use.

• Hair Type: Hair that is more porous or previously lightened may hold onto color longer. Color will likely not show up for as long on darker hair.

• Frequency of Washing: Frequent washing—especially with clarifying or sulfate-based shampoos—can cause the color to fade more quickly. Try to wash your hair with cool water, which helps to seal the cuticle and lock in color.

•Hair Products: Using color-safe, sulfate-free shampoos and conditioners helps preserve vibrancy.

• Hair Protection: Minimizing heat styling and protecting hair from sun exposure or chlorinated water can also help extend the life of your semi-permanent color.

• Hair Color Formula: Semi-permanent hair color formulas can vary in lasting power. Le Color Gloss Toning Gloss color can last up to 10 days, while Colorista Hair Color Conditioning Hair Mask can last for over 10 washes, fading gradually with each one.

For the best results, try to limit washing to two or three times per week and always use products specifically formulated for color-treated hair.
