This is my first natural winter and I have decided to keep my hair in two stranded twist so far. I have been co-washing and deep conditioning(with hair steamer) with the twist in every week, but take the twist down every two weeks to remove shed hair and retwist. I am curious about co-wash build up and was wondering how often I should really really clean with shampoo and acv rinse instead of just co-wash. If you have such a routine let me know what you do.
