Looks like a few triangles with a hair texture on them, and alpha at the end. Have you tried anything like that?

thuong,

Can you show us a screenshot of how it looks "bad". Maybe then we can provide better suggestions.

From that picture, it looks like you have alpha testing enabled, but not alpha blending.

Copy&Pasted from a tutorial I found with google:

m_pDirect3DDevice->SetRenderState(D3DRS_ALPHABLENDENABLE,true);		//alpha blending enabledm_pDirect3DDevice->SetRenderState(D3DRS_SRCBLEND,D3DBLEND_SRCALPHA);	//source blend factorm_pDirect3DDevice->SetRenderState(D3DRS_DESTBLEND,D3DBLEND_INVSRCALPHA);	//destination blend factorm_pDirect3DDevice->SetTextureStageState(0,D3DTSS_ALPHAARG1,D3DTA_TEXTURE);	//alpha from texture
