Best shampoo for fine hair, thickening/volumising

[SKLM]

Hello everyone

I had a baby a year ago and had a bit of post partum hair loss, plus a bit more due to low iron. I'm getting on top of the low iron but my hair looks so flat. It has always had a very fine texture but now there is much less of it.

Could anyone recommend a good thickening or volumising shampoo that won't make my hair greasy or break the bank?

Many thanks

No suggestions for a shampoo but Tigi small talk is brilliant. Just use a bit after washing but before drying.

Thank you I'll look into this :)

I like Elvive Fibrology.
