Barnet Woes: An end to the misery?

So just as I publish the below post about the misery of growing out my highlights etc, into my inbox pops some hope, in the form of a newsletter from Nylon magazine, telling me to soak my hair in tea for eco-cheapo-blondeness.

Here's the gist of what they say:

At Tela Design Studio, Philip Pelusi’s organic salon and tea room in NYC’s Meatpacking District, stylists actually apply teas as a conditioning treatment and color booster – a great way for clients to save money from frequent coloring visits. But, anyone can do this at home for the same great effect.

How to Use:

1. First, boil the tea of your choice. Let it cool to room temperature or below while you shampoo and rinse hair.

2. Then, working on clean, wet hair, pour tea over hair strands and work in for a few minutes with fingers.

3. The longer you leave the tea on your hair and the more frequently you apply it, the more staining the effect, so be careful not to over do it.

4. Rinse and apply conditioner for detangling.

For blondes, they recommend chamomile tea, and I actually have a big box of dried chamomile flowers I could use to make the tea. I could even do it while I sit and watch Hammer horror movies tonight when I get home from the gym.

I think I'll have a google around and see if this is safe. I don't want to end up looking like this:
