i have read multiple peoples opinion that using shampoo (or conditioner) to thoroughly clean brushes (once a week or so) isnt a bad idea. so that makes me wonder, as i know that not all shampoo is great on my hair. . . are there certain products that serve badger hair better? baby shampoo? dry hair shamoo? oily hair shampoo?. . . my inclination is in the direction of baby product, so if im wrong someone tell me before i go buy it.
