They wont run down with sweat. So carry on your daily routine with confidence. Just shampoo your hair to remove the hair fibres. It's not just the results, our ingredients are world class too! There are 2 main kinds of hair fibers, Cotton and Keratin. Cotton is much cheaper and be easily detectable but even worse, absorbs sweat and moisture and clumps!

The ingredients are specifically chosen to be non carcinogenic. No surprises then that our fibres are recommended by doctors and loved by our customers worldwide. It's not just quality and safety we focus upon, but also the right pricing.
