I wash or co-wash 1-3 times per week, depending on how many workouts I can sneak in.
I get about 0-3 broken hairs per month. But had been shedding pretty heavily (about 100 or so) hairs per day until I used Roux PC shamp & cond, a gloss treatment (which I will not recommend) and silicon mix conditioner last Saturday. I don't know which of these is responsible, but my shedding has decreased to about 5-10 hairs PER DAY! It's kind of blowing my mind.
