The color-rich pigments blend in so naturally that nobody will ever guess. It works on all hair types for both men and women, giving you that instant thickness boost whenever you need it. What I love most is how seamless it is. It doesn't clump or weigh your hair down, it just creates the appearance of fuller, denser hair instantly. With 13 shades available, finding your match is a breeze. Highly recommend adding this to your routine!

If you have grey hair or sparse hair at the roots, this Instantroot Hair Fiber instantly covers them. The hair fiber looks natural and covers tiny areas which need coverage. It gives hair a fuller look and can be washed off easily with shampoo.
