Argh! My newly-dyed hair is like straw!

And, most annoyingly, it gets so matted when I wash it. Can anyone recommend a good deep conditioner or something else that will make my formerly-soft hair lovely again?! Thanks!

This works well.

I was just about to suggest Olaplex but the PP beat me to it!

If your salon uses it, they can do the treatment whilst colouring your hair, it's made a massive difference to my hair, I used to get really dry ends but honestly this stuff is good!

Thanks for that. Anything I could do at home?

Elasticizer they sell it in M&S

You can buy it on amazon and do it at home yourself.
