Remember that colour removers work by shrinking oxidised colour molecules (or something to that effect), the post eraser basically re oxidises the hair, and thus enlarges the colour molecules that have not been removed to show you immediately if you have removed any colour before you re-dye. I didn't do this step because I wasn't planning to re-dye immediately afterwards so my hair would re oxidise over the few days after using the remover anyway. As it happened, I was not able to get every last scrap of red out and just the front part of my hair re oxidised to a pale red colour, the rest was golden brown.

If you scrub your hair really well when washing the Eraser out of your hair you should get the maximum amount of colour out (you seriously have to shampoo and rinse about 10 times). Just remember the results are not guaranteed, it really does depend on what you've already got on your hair.

My hair was porous from previous colouring, it did not become porous as a result of using the colour remover. To even things out I used Goldwell pre-colour and it worked pretty well. I got mine from an E-bay seller. I would also suggest getting a reconstructing conditioner like Joico K-pak to restore the hair.

There's so much information out there on colour theory, I don't understand all of it but I've got a pretty good idea about how hair colour works. I really do recommend you do plenty of research before you actually undertake any kind of chemical process on your hair.

Some really good resources are

Killer Strands read every single post here, this blog has everything you will ever need to know about dying hair, removing hair dye and caring for your hair.

Hair Care, 22000+ Hairstyles, Hair Articles, Long Hair, Short Hair a good resource for hair tips, also has a forum for asking advice and the like.

Ultimately, going to a hairdressers for colour correction is easier, but expensive. The Eraser isn't exactly cheap (about £18) but is way less than having the exact same treatment done at a salon. The benefit of having a professional do it is that they know what's happening to your hair.

It really is a gamble doing it yourself!
