i just posted somewhere about PTs also. My hair was also drooping so I did a PT. it improved my wave pattern, but now I have very frizzy hair, and it's the whole shaft not just the canopy. So I'm thinking the PT overdried my hair, it's stringy but not crunchy at all. But I noticed on my hair that coconut oil pulled my waves out. So u might consider that if it's pretty new to your routine.
