You can use yarn braids to start dreads, but it’s not for everyone and won’t always look great. The process involves braiding the hair, then as it grows out, continuing to twist the new growth until it locks up. Keep in mind, though, while some locking may happen over time in the braid, the shape will still be visible, so ideally, as the hair grows, you’d cut off the braided ends. As such, it works better for starting dreadlocks in shorter hair. Alternatively, you can use yarn to create faux dreadlocks, which look amazing.
