Looking for ways to make hair lighter

[Hair56]

Hi,

I recently got a new hair system and it's a shade darker than what I would normally get. My old hair system was quite light and faded so it's quite a shock.

Which shampoo / conditioner is best to remove some or the colour?

Any other techniques to lighten it? I've been out in the sun and it's not really done anything to lighten it.

Any help is appreciated.

Thanks
