What is the Differences Between Semi-Permanent and Permanent Hair Dye
Permanent hair dye is a long-lasting colour treatment that penetrates the hair shaft and changes the natural colour of the hair. Semi-permanent hair dye is a temporary colour treatment that coats the surface of the hair and gradually fades over time.
Permanent hair dye requires the use of chemicals, such as hydrogen peroxide and ammonia, to lift the hair cuticle and deposit the dye while Semi-permanent hair dye doesn’t, making them less damaging.
Permanent hair dye is more likely to cause scalp irritation than semi-permanent hair dye .
Permanent hair dye can cause the hair to become more porous, making it more prone to damage and breakage. Semi-permanent hair dye does not have this effect on the hair.
Permanent hair dye may not be suitable for people with sensitive scalps or allergies to certain chemicals.
Permanent hair dye is generally more suitable for people who want a long-lasting change in their hair color. Semi-permanent hair dye is generally more suitable for people who want a temporary change in their hair colour.
Permanent hair dye is generally more suitable for people who want to cover gray hair or create a dramatic change in their hair colour. Semi-permanent hair dye is generally more suitable for people who want to add a hint of colour or enhance their natural hair colour.
