  • AMAZING Product

    When I was younger my hair was really thick and full. But after having my daughter and having multiple surgeries, my hair got thinner overtime. Which took a toll on my confidence. I hated how thin and sparse my hair looked! I tried teasing my hair or using dry shampoo to create fullness, but it only did so much. After finding Perfect Locks hair fiber, this fixed it right away! My main problem area is the back of my scalp, but after using this product it looks like my old hair! Thank you Perfect Locks for creating this product! This is a really a confidence boosting product!

  • Yes hair building fibers really work

    Yes hair building fibers really work. They totally hide sparse areas

  • Amazing

    I purchased this product for my grandmother that has been thinning all around. I was able to show her how to use the kit and after one try she is a professional. She is glowing and loving this product from Perfect Locks. They have some many color options which made the processes nice and easy.

  • Fabulous! Better than expected!

    Newbie to this product and, I have to admit, skeptical. I really did not expect to love this, but the truth is, it is everything they say!I gave it a day off (from work) to play with. Started with the pump attachment because it seemed like a great idea. After 45 minutes of tiny little puffs I just wasn't impressed. So I changed out the puffer for the sifter. I was thinking it would be too much, and too uncontrolled. But it wasn't - it was just right. So next I wanted to REALLY give a good review so after a few hours I shook some more in to see how much was too much. I really never found that amount, but I DID discover that in getting careless with the application it ended up on my face. So my only advice is, put it on BEFORE your makeup. (And be sure your hair is dry.)Also, somewhere in the middle of the day I went for a bike ride - with a hair cover, visor and helmet. I was a sweaty mess and did not expect the product to hold up to this - but it DID! My scalp did sweat ALOT and most of my hair was soaked, but as it dried it just got fluffy!I tried the spray that comes with it. But I did not master this - it seems counter intuitive - make hair fluffy/increase volume then compact it down. I did not have the patience for this experiment. So I just don't use it.I left the product in over night and my hair still looked good in the morning. (Even after that sweat!) My pillow cases are not white, and I do wonder how much may end up there by morning. Not a big deal in theory, but you may want to experiment , if it could matter ;)It DEFINITELY made my hair look and feel thicker, fluffier and prettier. It washed out easily, did not irritate my scalp and was not noticeable (except in a good way!) I definitely recommend this product! It gave me back my confidence! Thank you!

  • Great product!

    This hair fiber set works well. I purchased the dark brown for my natural dark brown hair and it blends great. Unfortunately, the pump on mine came broken. If you're new to using hair fibers, be careful whenever you open the product. The hair spray/setting spray is a nice touch, but isn't needed to achieve a fuller look. Overall a good product, but not extraordinary compared to other (and less expensive) hair fibers on the market.
