We love our Madan brushes from
www.toplinepet.com
They are great on silky hair and do not break hair.
For serious tangles, I use a comb to gently pull them apart. A tight tangle, I use the tail of a rat tail comb. For looser tangles, I take one small section at a time and use the mustache comb (Madan has one).
What kind of comb are you using?
