Hair turning blonde during chemo

Hi everyone! I'm about a week away from my final chemo. I've had 4 rounds of dose dense AC and three taxol so far. I still have about 10% of the hair on my head and a good amount of eyebrows. I noticed many of the hairs on my head have turned blonde. I have dark brown hair. No grey hair as I'm only 35. The hair is not turning grey...it really looks blonde. I even have a few eyebrows that have turned blonde. Just wondering if anyone else has experienced this? I'm wondering if the hair is almost dead and lost its color. No idea what is happening but it's weird. I appreciate your response :
