My hair was doing the same thing last week. It needed to be clarified. I mixed 1 tbsp of baking soda in 2 quarts of warm water and poured it slowly over my scalp and through my hair. Then I rinsed well and massaged some conditioner through the length. I tried to comb some coney serum through it while it was damp-dry, but I think my cuticle was still up from the baking soda, which I plan to avoid completely in the future (opting instead for a clarifying shampoo). After my hair was fully dry, it was easy to untangle and comb again. At this length (tailbone), a coney serum or conditioner really helps to smooth and detangle my hair, but I must wait until it is dry.
