After years of high lift color at the salon, only to be in pain from stinging and redness of the scalp I came across an Italian salon product called sol_fine at Priceline, no stinging, brilliant color for blondes, I have a dark base, with Grey as well! I used a toner shampoo afterwards, turned out great! Do yourself a favor during these difficult times, only problem it's hard to get! And my sides went white due to my Grey, but overall a fantastic product!
