Favorite shampoo/conditioners or just about anything?

I have fine hair but a lot of it! My hair tends to fall flat no matter what i do and is currently color treated a burgundy red and tends to get oily within 24 hours. I’m looking for SLS/SLES free recommendations!

Right now I’m going back and forth with the Amika Normcore and Volume shampoo/conditioner soley because it makes my fine hair feel a bit thicker than normal. Most recently I’ve used Color Wow’s shampoo/conditioner which left my hair almost bone dry and the L’Oreal Bond Repair but I found it made my scalp flake a little bit. I’d love a whole new routine as my wedding is in barely 3 months and want my hair to feel better or starting to feel better by then, if possible.

What’s a product you absolutely loved?
