FAQs

What's the difference between semi- and demi-permanent hair color? ›

The most significant difference between semi and demi is permanency. Though both are temporary, demi lasts about 24 to 28 shampoos, and semi can last through about 3 to 6 washes.

Level 9 is that not-quite-platinum shade that's an extremely light blonde and will take most semi-permanent dyes effectively. Just be cautious if you are using a lighter blue or blue-based shade, as it can interact with the yellow pigment in your hair.

Permanent hair colour penetrates the hair cuticle, altering the structure of the hair shaft in order for the colour to be locked in permanently. Semi-permanent colour, however, is deposited on the outside of the hair shaft. Without anything locking it into place, the colour is temporary.

Demi-permanent hair color doesn't contain bleach and ammonia—it simply deposits color onto the hair. Since these formulas don't do any lifting, they shouldn't damage your hair whatsoever.

For those who don't have a full head of silver they're looking to cover, semi-permanent is a less damaging alternative. It just toned my grays down a bit, making the strays not quite as noticeable as they were before. The process also camouflaged the remaining highlights left behind by my last balayage treatment.

What is semi-permanent color? A semi-permanent color contains no ammonia and deposits only. It does not require mixing with a developer and lasts anywhere from 4 – 12 shampoos. This type of color is used to blend gray or enhance natural color and it's safe for immediate use after a relaxer or perm service.

Do salons use semi-permanent hair color? All the time! If you've ever blended visible gray hairs or applied a color mask, you've likely already used semi-permanent color. Salons use semi-permanent color to add depth to your color, grow out permanent color, or add gloss and shine to your strands.

At a level 10, most of the warm pigment in hair has been removed and the rest is toned out with cool tones. If your hair is dark-medium golden blonde this shade would be perfect to use to go lighter for a natural light blonde result.

Because this coloring process isn't as intensive, demi-permanent colors don't last as long as permanent shades. However, they are also gentler to hair, and offer softer regrowth in between color appointments.

Since semi-permanent color doesn't last nearly as long as permanent, it's not prudent if you're looking for an extensive change. It doesn't allow for major lightening or darkening, either. Odds are, you might be using this regularly for shine-boosting or color-reviving reasons.

What is the difference between toner and Demi-permanent color? ›

(Demi-permanent means exactly what you think, non-permanent color that will eventually fade.) Toners are also available in clear form, where they act like more of a gloss for hair. Toner can be applied in between color treatments, not just right after one, so that your color lasts and looks fresh longer.

The primary difference between semi- and demi-permanent hair color is how long they last after repeated washing and exposure to sunlight. Both methods are temporary compared to permanent hair color, with demi- lasting up to 30 washings, and semi- lasting about 5.

A demi-permanent will cover gray only if the hair is fine or porous. It will usually blend gray, making it appear highlighted.

Demipermanent hair color is like semipermanent dye's cousin that has a bit more staying power. While semipermanent color washes out within a few washes, and permanent color never truly leaves, hairstylist Larry Sims says demipermanent color lasts up to 30 washes, if you're cool with forgoing super hot showers.

Preserving Natural Tones:

Demi-permanent colors shine in their ability to enhance your hair without completely overhauling its natural beauty. Unlike permanent colors that may alter your hair's natural tone, demis work with your existing hue, adding depth and vibrancy without compromising what nature gave you.
