Because of the "tight" cuticle, it's rare for low porosity hair to tangle. My hair only tangles when I go too long without a haircut (I usually go every six weeks) or use a product with ingredients it doesn't like.

You don't say what products you are using, so I can't suggest any ingredients that might be giving you an issue. I'd suggest a haircut, clarify to remove any ingredients your hair doesn't like and a few DTs to moisturize.
