What Isis said, don't comb at all, unless hair is saturated with condish on wash days. I NEVER comb my dry hair. Use hands and fingers to moisturize and oil dry hair daily, rubbing product with palms of hands and finger combing ends as needed. I don't even try get in under the "jungle" when its dry 'cause I will definately lose hair, plus I don't NEED to mositurize my roots every day -- so long as I do a good wash /co-wash, condish and detangle once a week and use moisturizing leave-ins and oils to dry - my roots are good to go and I don't have to deal with it until next wash day. Just keep the visible hair looking good from day to day and no one has to know it's a "jungle" under there. If it looks good and swinging and not breaking, why worry about untangling -- just wait until your next wash (it will be waaaay easier to comb thru when saturated with condish and no risk of losing/breaking hair!) and in the meantime, enjoy your hair since not "working with it" everyday, plus all that time to do other things . . .
I have 4B relaxed hair and spend from 30 seconds to 3 minutes a day on my hair, if that. Once a week on wash days is when I put in any significant time "doing" my hair . . .
I've learned "less is more" and the less I do to my hair, the longer and stronger it gets . . .
