Surprising first time results

First application went great. Covered my thin spots better than expected. Wore a bright white T-shirt during application, sweated wearing a hat, and slept on a white pillowcase, none of which showed any noticeable residue. Showered the next day without shampooing and some came off but not as much as I expected. I have dark blonde to medium brown hair but chose ash brown which was a perfect match despite how dark the indication sticker showed. I’ll be buying again for sure.

Hiding a Misfortunate Circumstance

Thank you so much!! So my son just recently got out of the Air Force in Utah and and the barbershop on base was nasty!! They did not clean their equipment and cutting hair infecting a lot of Airmen. Shame on you!! So my son now has bumps and bald spots all over his head and the doctor said it may never heal correctly even after getting multiple painful shots in his scalp. Of course that made him self conscious and he would wear hats everywhere he went. I found this product and extensively read reviews and compared to other products on the market. The ratings and price solidified my decision to purchase this brand. I think I was more excited than he was when it arrived in the mail and I sprinkled it throughout his hair. As you can see, full coverage and you can’t even see his bumps and baldness!! Yes we hope this will eventually clear up but we are elated this is an option for him. He feels so much better about being in public and it lasted a couple of days without a touch up. Thank you so much for this product! It brings confidence back to those who need it!! You never know how important a head full of hair is until something drastic like this happens! I will keep purchasing this for him as long as he needs it. I’m just happy my son is happy again!!

It's not a spray, the instructions are simple to apply without!

At first I didn't know how this product would work when I noticed it was in powder form. The bottle allows for easy application by lightly shaking it above the area you want to apply and it immediately attaches to the hair fibers of your head and start to strengthen and support more body which also covers bald areas where needed. I love this stuff, it's much cheaper than the hair in the can my friends used in college.

Stop the Hair Thinning STRUGGLE!!

Seriously, don’t think about trying this product, just jump right in! I can’t believe how well it worked. I bought it on a whim after reading reviews- I’ve had hirsutism wreaking havoc on my hair since my late teens and I was almost ready to give up and simply shave my head.No need for that that! I haven’t had a head of hair that looks this full and gorgeous in a LONG time. If I could rate higher than 5 stars I absolutely would!! PLEASE STOP STRUGGLING WITH HAIRLOSS AND TRY THIS! It works, and it works insanely well!I will definitely be buying again when I need some more!

PLEASE give this a try if you want to conceal thinning hair

This product does absolutely everything it claims to do. I didn’t think it was possible, but I was willing to give the product a try, especially because 1) the product is able to be returned, 2) due to the large amount of reviews that rave about this company’s customer service, and 3) spending $20 in the name of self-confidence is an affordable risk for me. I’m happy to say that I’m extremely pleased after using this product several times. I was styling my hair in creative ways to hide thinning areas, but with this product, I no longer have to worry about trying to hide anything. It washes out easily and somehow applies where I want it (without spilling on face) despite the way the packaging makes it appear as if you won’t be able to precisely apply where intended. I will be buying this product again and again. My one dislike is that I don’t know if I am using the correct color for my hair, but it is good enough that I don’t want to spend the money and mess around with trying more colors and fussing with returns in attempt to get a perfect color match. This is just a personal issue and not reflective of product itself. I would recommend - if you have the money - to buy 2 or 3 colors in your first order, that you do so to find your perfect match and return which ones you’re not happy with. Thank you to Boldify for great product and great boost of self-confidence!
