Shampoo for coloured hair
Hi there!
I’d like to formulate a shampoo for coloured hair. I did a research on products available on the market and, from what I noticed, these shampoos consists on a gentle surfactant blend, conditioning agents (cationic polymers) and silicones. That being said, which silicone do you guys think is more appropriate for this type of shampoo. I was thinking about Amodimethicone at 1 - 2%. What do you guys think?
Any advice is welcome 🙂
Kind regards,
