I have really thick or thin hair will it be hard to get it to dread? - Dreadlocks FAQ's
There are 2 types of "thick" hair. One is just having a lot of hair. (high hair density) This makes dreading easier. The opposite is having low hair density or sparse hair. This can present a challenge but it's pretty easy to over come if you're aware of it ahead of time.
The second type of thick hair is having thick or heavy (coarse) hair strands like Asian hair. It will take a little bit longer for thicker hair strands (coarse hair) to dread since it's harder to get it to stay in knots and harder for the knots to tighten, but our instructions and products will ensure they will lock and the dreads will come out great - even if you have a challenging hair type.
Although Asian hair, and other coarse hair types take a little longer to mature, it's well worth it...the dreads look amazing! If you know that your hair is quite coarse you should plan on making your sections medium size for the best results. Larger sections often end up with too much hair to backcomb well since the hair tends to be very dense. 3/4" sections work exceedingly will for coarse hair.
Perming thick hair or leaving it in braids for a day or two before you backcomb will make it knot easier but it is not necessary. Of course using the Locking Accelerator before you backcomb and using the Lock Peppa during backcombing helps the hair knot faster by increasing friction. This will allow you to get the backcombing nice and tight. Coarse hair will require more pressure during backcombing to pack the knots down. Because of this backcombing often takes a little longer.
If you hair is really sparse, in the sense that you don't have many hair follicles per square inch, dreads usually make your hair look fuller. Red heads have the lowest hair density, brunettes are in the middle and blondes have the highest number of hair follicles per square inch. I've heard from quite a few fellas that were a little sparse up top. but once they got their dreads started they were really pleased with the way they looked. That's not to say it will work in all cases but don't let having somewhat sparse hair prevent you from trying dreads.
Starting dreads in sparse hair is the same as starting them in dense hair. You can adjust the size of the sections to make them look the way you want. The dreads will not get as large in diameter as they would if their were more hair but they will benefit from the fact that all hair that you shed remains in the dread. If your hair is thinning it's a good idea to make larger sections. 1" x 1" or 1.25" x 1.25" sections should work well. Having them too large will work against you because there will be more space in between the dreads taking away from the overall fullness.
