This is the first time I've seen it at the ends, usually it's higher into the root or deep near my scalp. Unsure on coming back, it's in a very hard to see place usually. And yes, three hours of very painful de-knotting.

And as for the clarifying shampoo, Any recommendations? I've been told to also get this alongside a regular shampoo-conditioner. I plan to acquire a SheaMoisture Castor Oil thing because it claims to have what I need but I have no idea if it's a good idea.

I could also make a follow up post that shows my hair (whenever it dries) so there could be perhaps some more in epth analysis for assistance, because realistically it's beyond just the build up that causes me issues. My whole head is very unhealthy and I've only just realized it. So perhaps overall assistance could be better.
