Anyone use a hair mask or use a really good conditioner?

I used to work at QVC and many people think its great, some leave it on overnight, unfortunately another one that didn't work for me

Philip Kingsley ‘Elasticiser’.
Very pricey but very good.
Shop around. QVC sell it, and you’ve got a sixty day guarantee to try it (Their customer service is second to none)
It was originally made for Audrey Hepburn!
It’s especially for damaged hair.
You put it on wet hair, leave on under a cap for as long as you want, and then wash and condition.
That’s the official advice, but I sometimes use a little bit as a leave in conditioner.

Everything I've tried doesn't make a difference either, I'm fed up of wasting money on promises of lucious shiny hair, I also want one that has a lovely smell but they are all too mild. I tried Molton Brown's own because the reviews were great but you can hardly smell it and it's just the same as the others.

My sister was recently told by her Hairdressers that salon brand shampoo and Conditioner is basically Herbal Essence.
That's was a surprise comment!
Why not give that a go before you spend lots of money?
Good luck sure your locks will be luscious soon.
