What Differences between Semi-Permanent and Permanent Hair Color

Semi-Permanent Hair Color

• Does not damage the hair.
• Lasts from 4-6 weeks.
• Gradually fades out until the hair is the same shade it started from.
• Semi-permanent hair color is deposit only, that is, it may temporarily darkens but wont lighten the color of your hair.
• Since it does not damage the hair, you may reapply them as often as needed.
• The only downside is their limited ability to cover gray hair.

Permanent Hair Color

• Permanently changes the hair color. Your own hair color must grow out to fully remove this process.
• It can be reapplied as substantial outgrowth of original color becomes noticeable.
• Each application damages the hair further, so it is preferable to apply the color only to the new hair growth.
• Permanent color can either lighten or darken the original shade.
• Permanent hair color also covers gray hair extremely well.
• The downside is that you must grow the hair out and trim it off to remove it.
• It can sometimes be dyed back to match the original color although it is extremely difficult to match the shade exactly. This is when a professional colorist really earns their money!
