EFFICIENT Keratin Hair Building Fibers, Hair Loss Concealer, 12 gm/0.42 oz., Black

One of the best hair fibers there is and for a reasonable price i enjoy this better then topix and xfusion personally....u will have more fibers pouring out witch means more on ur sink.if u have thin or thinning hair and dark hair i highely reccomend this...ur hair will look as good as it did at 16...and nobody will ever notice jus a few shakes and ur good. This product is not meant for bald or nearly bald ppl...its meant to hide bald spots and scalp mainly thinning hair. .im 35 and have been using for 4 yrs now. ..down side it will get all over ur bathroom and on ur pillows if u do not wash out.

This product works as stated and will cover any bald or thinning spots you may have. The only reason I switched to a different brand is because this one consistently clogged my shower drain after washing my hair.

I’ve tried several brands. I always come back to Efficient.

Got this for my husband and it did not work. Did not stick and made a mess. I was def sad about this.

This product works great and very affordable.

Great product, I've been a loyal user for quite sometime now..

Best fibers I have used so far!

allergic reaction to ingredients.

It does was its supposed to, but it clumps up and washes away with rain (kind of like mascara)

On time, amazing!!

Great product...good price
