The following is a paid review. So today I looked at Trustsource’s guide to hair loss. The site reviews 4 hair loss products: Provillus, Procerin, Thymusil, and Advecia. The site allows users to post reviews and shows you each products average ranking in a 5-star format. I always go by customer reviews whenever I buy a product so Trustsource seems like a very handy tool to see which products people love and hate. I just recently bought a digital camera, and with the help of customer reviews I got the most bang for my buck. In this case it seems that Provillus is the winner. With 4 customer reviews and a 5-star ranking, seems to be the best of the four in terms of hair loss remedies. Provillus also offers a 100% Money Back Guarantee. Always a good sign in my book, you don’t like the product? Just return it for a full refund. Provillus offers all natural ingredients including: Vitamin B6, Biotin, Magnesium, Zinc, Saw Palmetto, Nettle root, Gotu Kola, Pumpkin (Cucurbita Maxima), Eleuthero, Uva-Ursi, Muria Puama. Reading through the reviews, there are three 5-star reviews and one 4-star review. The only reason the 4-star wasn’t a 5-star was the customer wanted to see if the product worked a few months down the road, despite seeing results shortly after starting on Provillus. Overall Trustsource appears to be a very useful tool to compare products based on real customer reviews.
