I agree with sectioning.

But wish to add that,The shampoo may play a part as earlier stated. Consider a more moisturizing shampoo with slip.
Elucence for example makes a great moisturizing shampoo that I could even detangle my hair with.
I only expect my hair to tangle when I'm using a clarifying shampoo.

Blame Siri for the typos!
