Co-washing is the idea of washing your hair with conditioner and skipping the shampoo.
What is the benefit of co-washing?
Washing your hair with conditioner can gently remove build without overdrying the hair. The pH level of the hair is balanced and the hair is softened for easy management. If you have natural curls, the curls will become more defined. The conditioner can also increase the hair's strength and shine.
Is this for everyone?
Co-washing is generally used for naturally curly hair, but it could incorporated for any hair type. Before settling on co-washing there are a few things to keep in mind: If you have heavy buildup it might not clarify the scalp. In return, it might cause more buildup because conditioners contain cationic surfactants. Which is why choosing the right conditioner is important. This process might not be suitable for weak and over-processed hair because it will cause thinning.
How often should you co-wash?
It depends on your need and hair condition. The only thing to be careful about is if you notice any build up make sure to clarify your scalp with a shampoo or apple cider vinegar rinse. This will prevent a troubled scalp to develop.
