I currently have a sew-in installed, also. As for shampooing and conditioning, I treat the extension hair as if it was my real hair. Always detangle your hair before washing it, and be sure to wash your hair in one direction. This will prevent tangles. I will say that I find it easier washing my hair in the shower when I have a sew-in though, that way I can tilt my head back and not have to worry about lifting the tracks up.
At night time, I moisturize my braids underneath with a liquid moisturizer and then I wrap my hair. I brush my hair with a bristle or cushion brush, also.
