Review: A family favorite, especially for fine hair - I have fine hair, and had significant thinning around my temples due to styling and genetics. I've have tried a number of different products and this works the best. In 1 month, I've grown at least 1-2 inches of baby hairs. Although some of the new hair is gray, a win's a win! I have other family members that use the same solution and have seen similar changes. I also use this with Dr. Groot's Hair Thickening Shampoo, and Miracle In-shower treatment. When I was using only the Hair Thickening Shampoo, I didn't see much of a difference. However, when I added this serum plus the Miracle In-Shower treatment I saw an improvement with hair growth. Just fyi, it may take longer than 2 weeks to see a change. I'm not sure how folks are out of solution after a few uses. I wear this solution once a day and its lasted me a month already - and I still have plenty left. Perhaps to get the most of the product, when it's not in use, make sure that the pen stands upright and that you ensure the button to pump the is turned off to avoid spilling. Review: Not worth it - Used less than a week and already out. Only used in the front so not big area to cover. Not only have i seen no results (using the full system) but the product was either not new or definitely not worth the money. ## Features - CLINICALLY PROVEN: In 2 Weeks:Reduces hair loss due to breakage by 82.2%*, Reduces scalp redness, Reduces scalp moisture loss by 39.52%, Improves scalp hydration by 30%.
