Let us begin by stating the obvious: we are not doctors, this is not medical advice, and it’s a supplement, not active ingredient.  However, when a BupGrade staffer’s edges got thin, she got creative. No, grease and nimble index fingers would not suffice- she craved something more scientific, cleaner, and, well, less greasy. BioSil by Natrol is a natural collagen supplement said to aid in hair loss. We bought the 60-day formula and mentally prepared to be scammed. Pushing our desire for results out of our mind in the spirit of patience, we were surprised to realize a few things: (1) the bottle was almost gone, (2) so were our thin edges, and unfortunately, (3) ditto for our previously hairless neck.  In its place was a fabulously smooth neck, with some less-than-attractive, and longer than we’d like to admit hairs. In fact, our neck wasn’t the only place we discovered covert hair. We’ll preserve our image and just say this: after 60 days, we were hooked. Our skin was glowing, our hair was thicker, stronger, and less prone to fall out, and our thinning edges were a thing of the past.  We even recommended BioSil to our male friend, in place of Rogaine (it may not work, but at least your skin will be luscious). So we must say, go ahead, buy it and try it. Just make sure to pick up some extra tweezers while you’re in the store.  Available at The Vitamin Shoppe.
