Protein treatment & hair moisturisers?

Does anyone know of any protein treatments and hair moisturisers I can buy in the UK from somewhere like Boots, Superdrug, Sally's, a big supermarket etc? I know I could order some but I would prefer to buy it in a store if I can.

I finally got round to bleach bathing my hair on Tuesday, so I've been using lots of coconut oil as well as a Palmer's coconut oil protein pack and Lush's R&B hair moisturiser before the next round of bleaching.

I know the Palmer's one is supposed to be quite a light protein pack but it was the only one I could find in the shops. Also, before I did the bleach bath my hair was pretty much virgin so it's hardly damaged anyway.

The R&B moisturiser I found randomly in my house, but it's actually for very curly and frizzy hair, and my hair is the complete opposite. I tried it anyway, and it's alright, but I think it would work a lot better if it suited my hair type.

I like the palmer's protein pack so I don't mind continuing to use it, but if there's a better one around I want to switch to it (particularly now that my hair has been bleached). As for a moisturiser, I definitely want to use a different one.

Thanks a lot in advance! 🙂
