what is demi permanent hair color

Demi-permanent hair color is a type of hair dye that contains no ammonia and deposits color only. It is mixed with a low-volume developer to help open the cuticle and lasts up to 24-30 shampoos. Demi-permanent hair color is great for blending gray, enhancing natural color, refreshing color, toning highlights, or for corrective work. It is also safe for immediate use after a relaxer or perm service. Demi-permanent hair color is ammonia-free and mixed with a low-volume developer, so it washes out after about 24 to 30 shampoos. It is a little more permanent than semi-permanent color but less permanent than permanent color. Demi-permanent hair color is a good option for those who want to change their hair color but do not want a permanent change.
