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

This product works wonders in covering gray roots in between hair appointments. Just don’t put it on too heavily - a few quick sprays will do it. Lasts a really long time.

I was a bit apprehensive purchasing this spray... but after a few "trial runs", I have it down and the spray gives me a completely natural looking hairline. Blends in with my hair beautifully and I no longer have a receding hairline. Try it! Its fantastic!

Sticky, incredibly messy

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.

My hairdresser recommended this product and it works great! The only problem is that if you don't wash your hair before bed, it will get on the pillow case.

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.

I have androgenic alopecia for the past five or more years. I have severe hair thinning at the very middle front of my hair, and it is a pain to hide due to location. So I have been using Toppik spray in light brown to fill it in, but I always felt you could still tell it was a spray in and not natural. Well my go to has been out for months, and I knew I needed to find a backup. Well this backup has turned into my new go to. It blends perfectly and I can touch my hair more than I could with the Toppik too! Definitely recommend!

Works great !But you need to wash your hair before you go to bed, otherwise it will get all over your pillowcase.
