I am going to try Toppik. But am unsure of the color to purchase. My hair is naturally dark brown (with a GHOST WHITE scalp) but I like to highlight blonde or a lighter shade of brown like a caramel. Although I haven't done blonde in a while.....worried about the effects of that color on my hair as it needs to process longer.....but I really like my hair lighter. Anyway what do you guys think for a color? Is it true to color? Get a shade lighter or darker? Is there a safe can't go wrong color? Thanks so much!!
