I want to grow my hair like 5-6 inches in just 5 month, but since I started growing out my hair like in 1 year and 2 months they have grown like 2-4 inches and I need
8-10 inches before my senior year.

Hair simply does NOT grow that fast.

It cannot be done, my dear :)

Hair can only grow as fast as it grows, and there's no way to speed up the process. If you're wanting longer hair for a special occasion, look into getting extensions. There are expensive semi permanent extensions, and ones that you can simply clip in when you feel like having a longer look.

I'm afraid that would be your only option for the amount of growth you're looking for in such a short time.

Your hair will probably only grow 1/4 to 1/2 inch every four to six weeks, so what you want is impossible. Maybe you could get extensions.

If you see anything promising faster growth it's a scam - it's impossiible to make hair grow faster.
