Did you ever use wax? Is there a possibility it isn't mold but just lint/fuzz/dirt caught up in old wax?
the deep cleanse but go extra heavy on the teatree oil if u used wax do the wax remocal wax traps water and dirt making the dreads a perfect breeeding ground for mould but most ppl who trhink threy got mold it wqas only trapped fuxzzz does it smell like mold? did u ever wear a ghat with any wet hair
If it is really mold, adding grapefruit seed extract to your hair wash will kill it. Just make sure the GSE is diluted in with your hair wash stuff because it is very strong.
the white specks might just be the ends of hairs that have broken off. you can nip them off smooth with small scissors like embroidery scissors, and not mess with the hairs next to it. I no longer have dreads, went ultra long, and that method of getting out splits is called "dusting" or "search and destroy." could also be the last of the wax. Are your dreads long enough to soak on a pan? if so, heat that water UP to wax melting temps, but keep your scalp out of the water.
of u ued wax even obce i recomend reading through the wzax removal thread all the wayt u need water above 140 like he said be careful u can butn yourself also orange esential oil; will hep disolve it add that to the deep cleansde wiyth the greopaee seed extract ,maybe and very hot water wax is very hard to get out but the orangre oul will dissolve even glue
it's either split ends or the roots of hairs that have fallen out. Either way, there's no way to fix it other then snipping them off as someone else suggested. If it is due to split ends then consider being gentler with your dreads and moisturize to prevent new ones.
