Schwarzkopf - Nordic Blonde, L1++ Ultimate Lightener

I used this to bleach my hair when transitioning from dark to hot pink.
I would have taken photos, but because the amount of red in my hair it came out orange.
Here is a close approximation to how it looked:

Not the bombshell blonde I imagined, but it was my own fault.

This product was easy to use, smelt terrible (like a bleach will), and didn't damage my hair.

And it let me achieve this:

Klorane - Shampoo with Chamomile - Radiant Colour Blonde Highlighting

I got this as a sample in my Bellabox last month and thought I would give in a whirl!

First, lets get something out of the way right now... If you are going to send out samples of shampoo, in a sachet, MAKE IT EASY TO OPEN! My hands are covered in water, ready to shampoo and you pull this "difficult to open" stunt on me? NOT COOL, BRO!

It smells like chamomile tea (which I am not loving) and foams up wonderfully. It only needed one wash to clean my hair, which suits my lazy nature.

I asked my housemate if my hair looked different and he said "Is it... a bit lighter?". So maybe it does work to make blonde colours more prominent. Result: Inconclusive!

If you want more 'proven' lightening, then here is my solution:

Bleach your hair!

Price: 3/5 (rrp $9.95 for 200mL)
