Anyone have this problem? I have fine hair and also my mom. She have the same problem but she told me that it was because of the fine hair.

I don't want to cut my hair because i am in the process of growing.

And still if i cut my hair the knots will appear again, because last year i cut my hair, and the one-strand knots appear again..

Mix of 3C & 3B
Medium porosity
Low density
Medium width

Excuse my bad english
