I second the miconazole nitrate. Before I big chopped, my hair WOULD NOT grow due to dying my hair & constantly using heat on my poor baby. I used the cream (generic brand from Walmart which was $5) & I noticed a huge difference. My hair was magenta but my roots grew in fast & thick. I probably got an inch in about a month but then I big chopped it lol. I'm currently starting to use it again now & my hair is already growing after two weeks of using the cream twice a day everyday.
