I loved using the hair fuel. Its a very unique product, you can really feel it working on your scalp. It has helped with hair growth and thickness of my hair and its in much better condition than it was before I started using this product. My hair is somewhat longer, it had made a difference. I enjoyed using the product and would highly recommend it. You can feel the warmth of the product on your scalp and it didn’t cause any irritations. Its simple to use, easy to rinse out and is great. Recommended to all.
