Shedding of hair was significantly reduced using this product.

### ⭐⭐⭐⭐ 







  
  
    Great knot sealer...
  

*by A***L on Reviewed in the United States on May 6, 2013*

I am pleased with the sealant, but I do not like the smell. In addition, it irritates my skin from time to time. Besides that, the product has done well so far.

### ⭐⭐⭐⭐
