Post Keratin - 3 Weeks

It's been three weeks since I had the keratin treatment done. I've washed my hair 7x times and only once did I not use the recommended salon Matrixx brand shampoo/conditioner. By now, I thought I would have seen most of my curl return, but it doesn't seem to be the case. It air dries pretty nicely, with some volume having returned and a bit of a wave. I think there is one curl strand in there too. But nothing close to my natural hair. The ends however, do not dried very well, so I have been using the curling/flat iron to finish the look.

Positive things I have noticed:
- Matrixx Conditioner is great at de-tangling
- Less hair loss/breakage noticed during wash
- Post wash, my hair is soft and very manageable
- Air dry time has been reduced to two hours (from 6+ hours)
- Blower dry time has been reduced to 12 minutes (from 30 minutes)
- Hair is actually looks decent after using the blow drier
- Dried hair has shiny-glossy-healthy look

Negative things I have noticed:
- Hair texture feels hard, very "processed" when wet (without conditioner)
- Matrixx Shampoo leave hair feeling squeaky clean (you can feel the squeak too)
- Matrixx Conditioner feels slimy to the touch and does not rinse out easily
- Overall loss of volume and no sign of wave/curls returning yet
- Can not use any leave-in product or hair will immediately look oily (even on the ends)
- Hair begins to look oily and starts to clump two days post wash

Here are some pics after my hair air dried from last nights wash. I think there is one actual curl there, but mostly it's just wavy/straight. If I want to flat iron it would take about 10-15 minutes and look very sleek.
