Hair conditioner/shampoo recommendations?

[not_so_insig]

I need to find a new hair conditioner and shampoo. I had been using loreal hair conditioner and shampoo for years but they changed the formula a few months ago. I am finding it makes my hair look greasy now. Similarly I tried Alberto Balsam's hair conditioner but again it's making my hair look greasy.

I tried looking at tesco and amazon but found the choice overwhelming and I don't know a good one from a bad. I heard Tresumme wrecks hair so would like to avoid that. So yep if anyone has any suggestions I would like to hear it. Bonus points if it can be bought from either Tesco, Morrisons or Amazon. I have dry hair which is currently not coloured. So if it has an matching shampoo that would be great too. Nothing outrageously expensive - i can't afford to spend £12+ on a bottle. My mum has coloured hair and is finding that the loreal colour conditioner and shampoo is making her hair look and feel greasy so any suggestions for a coloured hair shampoo and conditioner would be good for her too.

So yep if anyone can help I would be grateful.

I use miniml shampoo from my local zero-waste shop and it seems to do the job but I'm mainly fussed about the planet tbh - my hair gets greasy whatever I do, but this certainly isn't any worse than other brands.

Thanks Jenna. I am currently trying ogx coconut conditioner and shampoo which seems to be better than the loreal. I also have an aussie conditioner and a different ogx conditioner so I am ok for a while but will take your comments on board.
