Unfortunately, the rate at which your hair grows is determined by your DNA and nothing on the market will make it grow faster. I suggest trying clip-in, glue-in, or tape-in extensions if they will blend well enough, you can go to a local beauty supply for help finding the right ones. A really nice lace front wig will look natural while you’re growing it out, but they are expensive. The last option is finding cute hats to wear for awhile.
I agree with socialbutterknife: the rate at which hair grows IS determined by genetics and no product can increase the time. However, there are still wigs and hair extensions. Plus, you could have a clever haircut. But don’t be fooled by some adverts: you wouldn’t believe an ad if it said a pill could make an amputated leg grow back. I am not being patronizing but it is a good example.
