Keratin treatment - which shampoo for aftercare please?

[Rarasong]

Hi there, I am having a Keratin treatment at the hairdressers, and need
to find a shampoo and conditioner which is both sulphate and sodium free. I’ve looked and looked but can’t seem to find a reasonably priced one - could anyone help please? Thank you.

Palmers coconut is free from lots - not sure about sodium.

I’d recommend KeraStraight Moisture Enhance.

There loads more affordable ones now compared to 10 years ago when I first started doing them. Try Organix/Ogx Argan Oil shampoo and conditioner, it's on offer at supermarkets, Boots and Superdrug almost all the time.

My mum has a keratin treatment and she uses the Hask range of shampoos. Think it's about £6.99 full price, but it's often on offer in Boots or Superdrug.

Olaplex

Thank you so much everyone! I will go and hunt 🌞
