@SpeckledyHen I think I will go into the store. I thought I would be able to work out what to buy on the website, but sounds like I should really go and see the products and have a consultation, so thank you for your advice.
The in shop advice I was given wasn't the product for me, but they gave a great return policy. I live their shampoo and conditioner, but I'm using what the shop assistant said was for afro hair. I have thick frizzy hair.
