Apple Cider Vinegar
Apple cider vinegar is another solution where you’ll have to get past the smell. It’s not as stinky as onion juice, but it can be a little overpowering. Apple cider vinegar is great for your hair because it cleans away anything that might be keeping your scalp blocked. When you have a natural pH balance on your scalp, you will see that your hair grows much faster.
Before you get started with this treatment, wash your hair in the shower. Then work a mix of apple cider vinegar and water into your scalp, and later rinse away with water. To make this mix, you won’t need as much apple cider vinegar as you might think. Take a container and fill it up about 10 percent of the way with apple cider vinegar, then fill the rest with water. Your scalp (and hair growth) will greatly improve.
