This protein (19,000 molecular weight) is also known as FGF-7 and heparin-binding growth factor-7 (HBGF-7). KGF is a member of the fibroblast growth factor family and has been found to stimulate hair growth. Cells that respond to KGF do so because they have receptors on the cell membrane that recognize the growth factor, normailly produced by cells near or far from the target cell. The binding of the growth factor to the receptor initiates a cascade of molecular events that will eventually lead, among other effects, to cell division. This powerful growth factor has been proven to stimulate hair growth in laboratory studies. ReVive has also used KGF in a volumizing serum which they sell for $600 per ounce.

This is one the specialty proteins (see also EGF and SOD made by Skin Actives Scientific using biotechnology. Biotechnology is a short name for an array of sophisticated methods that allow scientists to make large amounts of a single protein, nearly pure and fully active, at a fraction of the cost of extracting it from the original source material. Please note that our growth factors are sold for use in cosmetics only. Please ask us about wholesale pricing as well as custom protein development KGF is also available in ready-to-use serums: Hair Growth Serum and Eyebrow Serum .These serums combine the KGF with a nourishing and stimulating active ingredients for a synergistic effect. We recommend the serums to home users who want the maximum benefit from the KGF.

Each kit is enough for 4 fl oz of cream, lotion, or serum at approximately 0.00005% concentration (50 mcg in 120 mL cream). Use in your favorite cream or add to our Canvas Base Cream or a Sea Kelp Bioferment base. Mix thoroughly, but gently. Vigorous mixing will decrease the activity level of the KGF. KGF is kept highly concentrated to preserve its activity, therefor you will hardly see the KGF drop at the bottom of the small tube. Store the KGF in the refrigerator until you are ready to use it. When ready to use, add the contents of the second tube (saline solution) to the tube containing KGF and close. Mix by inverting and straightening the tube several times. The KGF is now ready for addition to your cream, lotion, or serum. Do not be tempted to use it more concentrated than recommended. A growth factor is similar to a hormone: very little (it is measured in micrograms, one millionth of a gram) will go a very long way.

  It has been over a month since I began using this for my eyelashes. I saw growth after 2 weeks. My lashes are not necessarily longer than they were before but I find it helps me from losing lashes. Since I hit 39-40 my lashes were falling out when I curled them. So this is an affordable solution! Erin
