Due to the shape of Curly Hair, it tangles easier, breaks easier and has a more irregular distribution of natural sebum, compared to straight hair. Additionally, Curly Hair is known to be more porous than straight hair.
Although there is currently a lot of discussion about the frequency that hair has to be washed (and there are scientific reasons behind that, e.g. it is a fact that wet hair is weaker), more important than the washing frequency is what you use to wash and how you wash your hair.
Hair damage accumulates on hair with time. That’s why, in general, a long hair has the tips more damaged (split ends) than a short hair.
Those damages are caused by many reasons, including washing the hair with bad products and putting a lot of friction when washing the hair. Studies show that friction contributes to remove up to 7 times more protein from hair, compared to a hair washed with very low friction (Hair protein removal by sodium dodecyl sulfate).
Knowing that curly hair is more prone to damage than straight hair, it’s especially important to select better the products and devices that are used to treat the curly hair and to be careful with the way that hair is washed. Those actions are much more important than the frequency of hair washing.
