                    My hair thinned on the top and has made me very self-conscience. This product has helped so much! It covers your scalp very well which make you look like you have more hair. It does take a couple times using it to get it right, but is so easy to use. Less is definitely more! I have learned over the last couple of years of using it, that you need to shake it further from your scalp so it won't clump.I definitely recommend this product!

                        Bosley hair fibers is the greatest. My hair is very thin a beauty consultant suggested I try using hair fibers to fill in the bald area. Oh my goodness what a difference and gives me confidence when I am in public. I have suggested Bosley to many others.
                        Have tried several different brands of hair fibers but also come back to the best..
                        Thank you Bosley for this wonderful.product.

                            Hi Annie so sorry to hear you were not satisfied with your transplant results.It is my understanding it sometimes it takes several surgeries to get the desired result and that depends on you hair density were hair is taken from. We are a sister company to Bosley INC and retail Bosley Professional Strength products. I would recommend trying our Bos Revive starter kit to help give your hair more thickness and volume. We do have an Auburn Fiber but Ulta carries 4 of the 7 colors. The fibers do give great coverage. Search on our website Bosleypro.com for where to buy

                            The fibers are electro-statically charged to cling to hair, but to increase the bond we recommend using the Non Aerosol Fiber Hold spray which will keep them from coming loose as long as you are not running your fingers through your hair. We do recommend you brush out the fibers in the evening before bed as movement at night can break the bond with the spray

                            Hi GG, The hair fibers are a temporary coverup and are designed to be reapplied daily. They are easily removed by brushing out or shampooing. So they will not last more than 1 shampoo. As to using we recommend you curl your hair first then highly lift the hair and shake on the fibers then lightly comb in place and spray using FiberHold spray to help bond them to the hair.

                            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.

                            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.
