      Fills in my bald spots

        Comments about Bosley Hair Thickening Fibers:

        After I had chemo, my hair came in curly, but didn't come back in some places, which is very embarrassing ti me. This product allows me to cover my bald spots. I just shake it over the spots, and abracadabra, the bald spots disappear. It is important, however, to pick the right shade.

                I have used seveybrands, this is my favorite. I just sprinkle a little in the spots where my hair is thinning. It's quick and colors my scalp to match my hair. My hair looks so much thicker, and it lasts all day at work until I wash it out at night.

                This product does a nice job of filling in thin spots. I was disappointed that the photo in the store showed an applicator that was not included in the box with the product but it seems to work fine just shaking it out without an applicator.

                          A:

                          Yes you can use with hair color, just pick the color closest to the color you are using. It is also helpful when you want to temporarily cover out growth in the crown area.
                          The color is embedded into the fiber so it does not run or stain even if it gets wet.

                      • Q:

                        is this product sticky? Does it tend to cause breakage (my hair is thin and fragile)? Also, does it come off on pillow cases, etc?
                        thank you

                          Hi Les,

                          The hair thickening fibers are not "sticky". They do not cause breakage in hair. They are normally shampooed or brushed out before sleeping. And yes, they may come off on your pillow if you leave on the scalp. The hair thickening fibers are for a temporary, cosmetic cover up of areas that are thinning.

                          I would try the light brown as it would blend with the brown, gray and blond highlights.

                          We recommend choosing the shade that is most similar to your hair color for most natural looking results; for you, we suggest choosing Medium Brown.
