The demi-permanent hair color is great for darkening hair, so if you are looking to lighten your hair color, you should try other types.
Semi-Permanent Hair Color
Like the demi-permanent hair color, the semi-permanent hair color is an ammonia-free hair dye, and unlike the demi-permanent hair color, it doesn’t require a developer to be used.
It is also referred to as toner, gloss, or stain, this is because it only coats the surface of the hair and does not penetrate the hair strands, this indicates that it doesn’t cause any permanent change to your hair structure or color. The semi-permanent hair color lasts up to five to twelve shampoo washes.
The semi hair color is best if you intend to keep your natural hair color but still switch to the colors once in a while.

Differences Between Semi And Demi-Permanent Hair Color
The major difference between these two hair dyes is in how long they last in the hair.
