Demi Dye Characteristics
How long does demi permanent colour last? Typically 4-6 weeks, depending on hair porosity and care routine. It can darken hair but cannot lighten existing colour.
When to Choose Demi Dye
Choosing between demi gloss and demi glaze shouldn’t be too difficult. Generally, go for demi gloss to enhance your current hair colour for shine and dimension, refresh faded hair, and minimize grey hair. If you opt for a demi permanent solution to perfect pre-lightened hair, demi glaze is ideal when you have highlights or balayage and want to perfect the tone.
Both demi gloss and demi glaze are modern hair colouring methods and techniques with advantages and uses for all hair types. The key difference between permanent and semi-permanent solutions is that demi products offer a middle ground – they last longer and provide more coverage while being gentler.
Understand the differences, and you can enjoy them to the maximum. If you are unsure or need the best outcomes, consulting a professional hair colourist is recommended to achieve the best results.
