I tried this today, the re-wetting that is, and didn't get great results. The dew point was 61 and my hair turned out really puffy.The 3 a,b and c curls were extra curly while the 2c hair was just puffy. I think humidity is especially bad on my hair due to the variety of waves/curls.It seems to exacerbate the difference in curl patterns.
The only thing I'm sure of is that it was better than it would have been had I not re-wet. Its hard to tell from the pics. But, there is a distinct difference in clumping. After re-wetting, my hair was smoother and more clumped. I'll try again.
