Review: Nothing Comes Close to Keratherapy Keratin Spray - If you have thinning hair and can't afford a hair transplant, then this is the product you've been waiting for, and that can improve your self-confidence. Here are some tips for proper usage that I've developed by trial and error after using this Keratherapy spray: (1) Place your hand over your forehead close to your hairline so that when you spray the product, it doesn't end up on your forehead or face. (2) Spray evenly over the surface of your hair, front, top and back, holding the can about six inches from your head. (3) Once you're satisfied with the extra volume your hair now has, the key is to use some hair cream or, even better, spread a thin layer of coconut oil on the palm of your hands and then pass it over your hair. Then, gently brush your hair until it's easy for the brush to move through your hair. (4) The reason for step (3) is that the keratin fibres, when they bind to your hair, will leave it stiff and difficult to brush. (5) One last tip: I would use this spray in a room that no one in your house uses regularly, because over time the sprayed fibers can end up coating everything with whatever color spray you're using. I learned this the hard way so I now use the spray and a small attic room in my townhouse. Other than the above tips, this product is absolutely amazing, and trust me, I've tried many of the competitive products and nothing comes close to this one.
