How can I get my hair to grow thicker?

What are some ways to get my hair to grow thicker? All my friends have really thick hair and can do all kinds of cool hairstyles, but my hair is usually too thin and I hate it and want to know how to make it thicker.

"Here's a protein hair mask that should strengthen, repair, and thicken your brittle hair and soften your strands. This can improve your hair's health without costing you a fortune.

Recipe:
Mash 1/2 cup of avocado, a tablespoon of mayo, and a tablespoon of honey together. Blend well. Let it sit on your hair for 20-30 minutes. Rinse your hair with an all-natural hair growth and thickening shampoo. Do this at least 2-3 times a week. Within one month, your hair should be brought back to life, without having to get an expensive salon treatment.

The best all-natural hair growth shampoo that most stylists are using in my region is A Double Portion Super Hair Growth Shampoo. Beauty 4 Ashes makes it and it is full of the best natural hair growth stimulating ingredients on the market, including: grapefruit oil, sage, rosemary, vitamin e, coconut oil, and aloe. It smells great and has transformed some of my clients' thinning hair. You can find it at www.discoverb4a.com... or it might be in tradesecrets.

Lastly, get plenty of EFAs by eating more fish."

Good advice I use that beauty 4 ahses super growth shampoo and my hair is growing faster.
