I went to a salon around 20 days back to get two light brown chunks in my hair. My hair are jet black. They colored it blonde instead of light brown. So I asked them to color it back to black. Now the black color is slightly changing to dark brown. Nd I can even see a few strands of blonde color. Those two strands are at the lower back of my hair. Hair of that portion are dry with lot of splitends. What should I do now. Shall I get them cut? How long will I have to wait to get them cut? Like should I le the roots grow? And I can't now even differtiTe between my actual hair and dyed hair.. My hair are even falling and becoming thin.. p.s I use loccitaine repairing shampoo and conditioner.
