I have heard of ladies doing wash n go's while transitioning. However, I think it depends on the type of hair that you have. For me I can't because my relaxed ends are bone straight (no curl even when wet). So I do bantu-knot outs or braid-n-curls on my hair that way I can wear my hair out and the two textures blend together.
There are some great tutorials on you-tube on how to do the styles. HTH
