The level of damage may vary so depending on how damaged your hair is I would say try a sulphate- and sodium-free shampoo. It also depends on your hair’s natural texture and how much colour you have on your hair over all. You might need something for colour-treated hair or something for highlighted hair. You might need a shampoo for thick hair or fine, something with thermal protection in case you heat style your hair or something for chemically treated hair in case you have had a chemical service with your colour. Review the above mentioned and then decide on the shampoo you feel best suits your needs.
