Review: The best by far, outstanding product. - This is outstanding fibre touch up. I’ve tried a fair few different products over the years, and finally one that works so well. The added brush pen it comes with is genius idea and makes it much easier to get a perfect finish, it’s nice and soft and effortless to apply on. Really good quality fibre and thick. Will hide them dodgy spots and no one will know. My hair is black and I always go a shade lighter so the dark brown works perfect and blends in well so it doesn’t look too obvious.
Review: works great! - Great product! I find it better than other brands I have used. Its easy to use and it really is water proof. no running when It was raining. Its a real game changer for my confidents too as it fills in my hairline and makes it looks thicker.
