Hey, I used to have quite thick hair until I started dying it black (for an ex who loved dark hair) and as time went by I kept dying it myself however instead of just doing my roots I would foolishly empty the whole bottle of dye onto my head and it just got thinner and thinner, along with letting a 'friend' mess with it (she basically just randomly cut it) - however this was around a year ago and I've been to a hairdresser, had it cut a lot shorter with short layers and its faded to a dark brown as opposed to black now however its no where near as thick as it used to be. Are there any products or natural remedies to thicken hair? I'm aware of Vitamin C and just the general diet of course. Thanks xxx
