ANYONE'S hair will dread if left clean, unconditioned and unbrushed, no matter the race, even Asian hair types. Its also best to not get them done in a salon or by a loctician, they use and promote the most harmful methods like wax, interlocking, crochet, maitenance, and not washing. Once wax is used its there forever, nearly impossible to remove and makes dreads retain moisture causing mold and dread rot over time. Interlocking makes dreads too tight to the scalp causing traction alopecia. Healthy dreads should have 1-4 inches of loose hair at the root even when mature. Crochet rips hairs to shreds causing extreme frizz when the broken hairs pop back out which then get recrocheted causing even more damage, crocheted dreads are extremely weak and often just break off. Dreads don't require any maitenance, all it does is damage them and slow down if not reverse the dreading process. Forms of maitenance like retwisting also cause traction alopecia.
Yes, you can get dreads in mixed hair and what they look like depends on what method you use.
