Keratin straightening, what shampoo????? 😳

[stillstanding51]

Help….
What can I grab in Boots or Superdrug that’s safe to use on Keratin straightened hair?
It cost a blinking fortune so I’m hoping to preserve it for as long as possible
The hairdresser told me L’Oréal professional stuff would probably be ok but ive noticed it contains sulfates and sodium carbonate which I think is salt and is a no no
Any help muchly appreciated

Just look at the ingredients and find one which doesn't have salt in it.

I use https://www.amazon.co.uk/URTEKRAM-Rose-Shampoo-Size-shampoo/dp/B00J9SCR28/ref=sr_1_8?crid=2D5YKNBZ6X7MM&keywords=urtekram+shampoo&qid=1696525546&sprefix=urtek%2Caps%2C163&sr=8-8

because I have really sensitive skin and most shampoos irritate my scalp, and my keratin lasts for ages.

I meant sodium chloride, not carbonate 🙄

Palmers do one and it’s only about £4 rather than some of them which are nearer £12
