Keratinocyte Growth Factor BT (KGF)



SKU 146

Quantity Price
10+ Items $11.25

This protein is a member of the fibroblast growth factor family and has been found to stimulate hair growth. Our cells respond to KGF because they have receptors on the cell membrane that recognize this growth factor, which is normally present in our body but which declines as we age. The binding of the growth factor to the receptor initiates a cascade of molecular events that leads to cell division.

ReVive uses KGF in a volumizing serum which they sell for $600 per ounce.

KGF is available in our ready-to-use Hair Care Serum and Brow and Lash Serum. These serums combine KGF with nourishing and stimulating active ingredients for a synergistic effect. We recommend the serums to home users who want the maximum benefit from KGF.

KGF can also help slow down skin thinning that occurs with age.

Additional information for KGF can be found here:

KGF is kept highly concentrated to preserve its activity, therefore 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 tube with the clear cap (saline solution) to the tube with the yellow cap (KGF solution) and put the lid back on. Mix by inverting and straightening the tube several times. Make sure the solution is mixed thoroughly, but gently. Vigorous mixing will decrease the activity of the KGF protein.

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.

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 our Sea Kelp Coral.

Keratinocyte Grwoth Factor (KGF) suspended in ammonium sulphate/water solution.

This growth factor has been proven to stimulate hair growth in laboratory studies. It also accelerates healing and increases skin volume. It may help prevent hair loss during radiation therapy during cancer treatment.

Keratinocyte Growth Factor (KGF) binds to the KGF receptor on the cell surface, acting as both a growth and survival factor by stimulating epithelial cell proliferation, differentiation, and migration, and promoting a number of cell protective mechanisms. KGF 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, normally 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. Keratinocyte growth factor has been shown to regulate proliferation and differentiation in epithelial tissues, and may regulate the stem cells of the hair follicle.

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.

    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

    I originally bought this to help my skimpy eyelashes, and to help thicken my hair by reducing shedding. I can honestly say that after about 3 or 4 weeks, I noticed that my eyelashes were hitting the lenses on my glasses - something that never happened before. I also noticed that my hair immediately shed less in the shower - down from a disturbing clump to 1, 2 or none per shower. I also noticed that using mascara now made more of a difference, whereas before using this product, mascara didn't help much (and I kept using the same mascara brand.) Lastly, when I started seeing my husband, I turned him onto this product, since he was concerned about a thinning patch on the crown of his head. (I also suggested he take biotin supplement, which he did, and still does.) He immediately noticed he shed less hair in the shower, and I noticed the patch slowly filling-in, and is barely noticeable now at all. In fact, his whole head of hair looks much thicker and healthier - he has baby fine hair to begin with. We are both 53. I'm a VERY skeptical person, but I have watched this product work as promised on both myself and my husband. I highly recommend it to anyone who wants to improve their lashes or hair. :)

    I love this! I have long had this one completely bald spot that refused to grow no matter what I did. Very distressing for a a woman in her early 30s. I had tried this before in some liquid based applications with very little success. I finally incorporated it into a cream with micro circulation stimulators (ginseng, ginger and gingko biloba) and not even a month later I have peach fuzz in that spot!
