It is common to blend the two textures which will offer you more manageability. You will be required to buy at least two pouches and alternate the tracks. You can alternate the tracks halfway towards the top for a much better blending which will even create a more natural look. Also, note to put the Kinky 3B-3C textures as the first 3 tracks in the back of your head and Tight-Kinky 3C-4A as the last two tracks which will blend better with your natural hair leave out better.
