Always follow up with conditioner. If your hair is really dry, you should follow your co-washing procedure with a masque or a deep-conditioner. These treatments are very much needed after washing your hair with a mild shampoo to help restore moisture and balance out the scalp. 5. Use a volumizing product to add volume to fine hair. Fine hair tends to be more prone to breakage because of its small diameter; therefore, it needs more protection. Using a product with protein and silk can help fine hair retain more moisture and avoid breaking down too quickly. 6. Avoid heat styling right after co-washing. Heating products such as curling irons or straighteners can cause damage to your hair's cuticle layer, which could lead to breakage. Wait at least 48 hours before heating style your hair. 7. Don't wash your hair every day. Washing your hair every day will wear out the cuticle layer faster and lead to more frequent breaks. It is recommended that you wash your hair no more than twice a week for best results.
