grow my hair really long

I chopped my hair chin length as a symbol of I don’t care what my boyfriend thinks, I’m going to live my life as I please. And then it turns out that he liked it. Oh well, I chemically straightened it and dyed it reddish and now plenty of my hair is falling out. I’m trying not to wash it often because so much is lost when I do. I bought this shampoo and conditioner over the internet that is supposed to help your hair grow faster. It’s coming in a few days, hope it works. I’m so over my short hair now.
