The first thing to do is - don't tangle it while shampooing it! Remember, you are not whipping cream.
Wash gently and don't pile the hair up on your scalp. Start from the bottom ends with a “wet brush”, or “wide-toothed comb”. It is your hair so you can ease up when, or if, it becomes uncomfortable. Use your leave-in conditioner, or other styling product - that can help too. Tools for detangling include a “wet brush”, or a “wide-toothed comb”, and your fingers only.
