Maybe a question like "What is a permanent hair color?" If you were ever in a situation where on one hand you have to totally hide your greys, and on the other hand, you want to change your look from dark brown to deep burgundy, come into your mind. 

 

The permanent hair color, unlike the temporary ones that only "stain" the surface of your hair, is a chemical process which actually goes to the core of your carbon-based structure. It doesn't just go with the top of your hair; it penetrates and stays there. 

 

How the "Lock-In" Works

 

To figure out what permanent hair color, you need to compare your hair to a tree. It has the outer part (the cuticle) and the inner part (the cortex).

 

  • The Opening: An alkaline agent (usually ammonia) by swelling the hair "bark" makes the area that needs changing to be open.

 

  • The Entry: Very small color molecules move to the center.

 

  • The Expansion: The molecules meet a developer (peroxide) which makes them expand so much that they cannot go back out once they meet each other even one in the center.

 

That is why the word "permanent" is emphasized. The color is physically intertwined with the hair until that strand is either elongated from the scalp or cut off.

The "Regrowth" Truth

 

The most important thing to remind yourself about permanent hair color is the "line of demarcation". That is where your natural roots will show up because the color does not fade, thus, the place where your hair grows will be visible. My friend Priya uses permanent color for her dark hair, but she needs to set a reminder on her calendar every six weeks for root touch-up so that the color blends perfectly. 

 

The Takeaway

 

If you want to change your hair completely or cover up greys 100%, permanent hair color is basically the "gold standard". It is chemically binding, but it allows you to get the most beautiful, long-lasting results possible. Just make sure that you are ready to part with your roots every month!

 

Frequently Asked Questions

 

Q: Does permanent hair color harm hair? 

 

It leads to dryness because by nature it opens the hair cuticle. To keep hair healthy, it is recommended to do a "plex" treatment or deep conditioning once a week.

 

Q: If I dislike it, can I wash it off? 

 

Definitely not. The color is inside the hair; thus, you will need a "color remover" or a professional stylist to help you find your original shade again.

 

Q: "Ammonia-Free" means non-permanent, right?

 

Not really! Many modern permanent dyes use other ingredients to open the hair cuticle, which makes these dyes more gentle and odorless, but they are still ‍‌‍‍‌‍‌‍‍‌permanent.
