Keratherapy Keratin Infused Perfect Match Fiber Hair Thickener Spray, Medium Brown, 4 fl. oz., 140 ml - Volumizing, Thickening, & Concealing Hairspray for Scalp Coverage, Roots & Thinning Areas

Best product for thinning hair, hands down. My hair dresser has used this on me for years, and I finally ordered some to use at home. I'm sold!

Literally the best I’ve tried so far. I just do small spot sprays on top (crown) since that’s where I’m thinning the most. Then I do a dry-touch hairspray lightly over it and that’s it. Looks real, even in sunlight walking around Disney sweating in the summer. Nothing came off when sweating and you can’t clock it even up close. I’ll come back and post pics soon.

Heavy and dark.... makes your hair look bad!! Wish I could return it since it's so expensive but it's not allowed!! This is messy and horrible, highly DONT RECOMMEND!!

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.

This stuff works GREAT, especially if you have thinning hair or hair loss. Watch a few YouTube videos for guidance. That being said, it is Messy! There will be overspray on your countertop and floor. Not necessarily noticeable to the naked eye, but when you wipe things down, you will see it. When I use now, I go out to the garage and spray. If hair loss is not your issue, there are other sprays out there to cover gray, etc. This fiber spray helps my hair issues tremendously.

This is one of the best hair products I have used for hair enhancing. It gives a nice full look over thin hair and the smell is very nice. When using cover your eyes and just spray where thinning. You can also choose different colors. The downside is the high price.

My hair is thinning and I ordered several different products to try. This is by far my favorite. I’m blonde and it’s hard to find a match so this one is the closest. I use like you use a dry shampoo so I’m all about the extra lift and body it gives my hair.

I have very thin hair, you can see through to my scalp easily, which is embarrassing to me. My sister is the same way, and one day her hair looked great, almost thicker, and I was like OMG, whatever lotion or potion your using I need to use it too. She said it was this stuff, so I ordered it from my Amazon app right then and there. Even my co-workers are like "your hair looks good", they have no idea what I'm doing different. They think all I got was a haircut. Life changing.

I really had my hopes up for this but unfortunately this was a massive let down. The shaken in hair fibres is still the best way to go by far. This melded well with the hair but did not for the balding areas where as toppik or surethick works wonders. The aerosol makes it wet and too much pressure. Huge miss, wayyyyy too expensive. Truly disappointed I was excited for a quicker easier spray solution to the fibers but I will go back to those. Really wish I could return this.
