"Not sure why people let their hair fallout anymore. Products like Spectral DNC-L are available that are based on sound science to help stop baldness, or even reverse it. A brief review of the ingredients over at the DS Labs website will show the data, and sources, of how the product works. The best thing to do is to purchase a few bottles and try it out yourself. It is generally agreed upon by the online forums that 1 year is best to really judge if you can have regrowth but you should be able to notice something within a few months. Spectral DNC-L will work the best on bald spots but if you're thinning it will work as well, you just have to keep rubbing the product into your scalp until it completely dries off of your hair. I was using Spectral DNC for a little over a year and made the jump to DNC-L for the extra ingredients. I am purchasing another bottle because I like the boost I'm getting from these ingredients. Also three pumps is sufficient enough to just about cover most of the scalp as well."
