Fine Hair Shampoo - shampoo voor fijn haar

I know I am at fault here since I had a lot of high expectations for this shampoo with it being in the pricier range and knowing that Ouai is founded by Jen Atkin. I like the smell of it but other than that I don’t see that my hair gets less greasy after using it for a good three months, I still feel like I need to wash my hair every 2-3 days when I was hoping to stretch it until at least 4 days max. On the other hand, there is a bit of volume after I wash it but I still have some frizz.

Who has used this and do you recommend for fine/thin hair? I'm struggling to find a shampoo and conditioner that doesn't make my hair greasy quick but that can also help thicken my hair possibly? Any advice would be appreciated!

This is really the best shampoo I've ever used! Smells super nice and is really great for my fine hair. The shampoo cleanses well, but without drying out and does not make it heavy either. It is also super convenient that you can buy a bag afterwards to refill the shampoo.
