What is the best natural shampoo and conditioner to use

When having highlights to cover up the grey hair (!)

Thank you

How damaging is the sun to our hair? Was just reading this https://www.aad.org/public/everyday-care/hair-scalp-care/hair/curly-hair-care

How often should I be cutting my hair to keep it healthy?

My curls look great after I wash my hair... but they don't look as fresh on day 2 and day 3 of not washing my hair. Tips? (Also double checking that it's best not to wash your hair every day?)
