Out of date Philip Kingsley hair drops ok to use?

[cpbp]

Hi,

I have a few months supply of some very expensive hair "drops" that I bought ages ago from Philip K whilst they were still in date. Have discovered that the "use by" date is July 2010. Silly me didn't use them and my hair is proof of that!

Does anyone know if there is any point in my using the out of date stuff- presumably Philip K would say not and to buy a fresh supply -but I can't afford to at the moment.

Really hoping I haven't wasted £££!

Thanks for reading this.

I assume they only have a use by date to make sure you buy more. I woudl use them- what harm can it do
