So, I've been growing my dreads for around 2 years now. Achieved by the neglect method (although I hate that name for it). Every month I do a deep clean using BS & Tea Tree Oil and often use a bar of soap containing no residue, washing my hair about 2/3 times a week.
A couple of days ago I found in a couple of sections what appears to be white/grey sticky stuff. There is no smell so I don't believe it's mold. However I've noticed that when I wash my hair the sections containing this white/grey stuff stays wet for quite some time longer than my other sections.
I mostly use a hairdryer to dry my hair and never use it past the lowest setting.
I did a deep clean after discovering this white/grey stuff and it hasn't gotten rid of anything. So I'm quite confused.
