Help/Advice & Knowledge required please.

Hi

I'm new to these forums. I'm Scott, nice to meet you (so to speak)
So... I want to dye my short dark ash blonde hair to a very light beige blonde shade.
I tried platinum last year but it didn't suit me. I'm thinking a very light sandy colour will be better.

To the best of my knowledge, this is how I think I can achieve that shade:

1. Prelighten hair to a pale yellow using bleach mixed with 9% creme peroxide.
2. Mix L'Oréal Majirel 10.13 with 6% peroxide and apply to dry hair and leave for 30 minutes.

Is this correct and if not can you offer any other suggestions? or alternative methods please.

Thank you.

Scott

Thanks for the reply. I learnt that 10,13 has been discontinued and not only that, it wasn't the right shade for the tone I desired.
I bleach my hair to a pale yellow and then tone it with Majirel 9,13 mixed with 3% for 20 minutes. The shade turns out really lovely and high end looking.
