really good
when i first started using it, i could see a lot of hair shedding out on the brush and i was kind of surprised.  but now i have a feel for it and the brush is almost clean by the time im done using it.  i use this and the natural boar bristle brush ive had for years to distribute the oil more.  i usually wash my hair once every three weeks.  I know that sounds disgusting but my hair is past my hips and i need as much oil as i can get to go all around my hair so it doesn't dry out.  but this is the first time i've actually had to wash my hair once a week.  im producing a lot more oil, maybe because the comb stimulates my scalp somehow?  All i know is nothing about my diet, exercise or life has changed except buying this $35 comb and I'm becoming annoyed throughout the day because my scalp is hot with oil.  and my hair looks great, so healthy and it feels good.  and combing my hair has become a much better task with this tool.  i know it's just a comb but my hair is really important so this is an important tool that people should invest in cuz everyone needs a comb so might as well get one good one.
