Customer Questions & Answers

  • Question: What are Top Secret Hair Thickening Building Fibers made from?

    Answer: Top Secret Hair Thickening Building Fibers are made from natural keratin fibers, which mimic the appearance of real hair. These fibers bond seamlessly to your existing hair, creating the illusion of volume and density. Unlike synthetic fillers, keratin offers a soft and natural look, ensuring that your hairstyle is enhanced without drawing attention. They are also static-resistant, making the fibers cling effectively without clumping, perfect for any hair type.
  • Question: How do I apply Top Secret Hair Thickening Building Fibers?

    Answer: To apply Top Secret Hair Thickening Building Fibers, shake the container gently to loosen the fibers, then hold it over the areas of thinning hair. Gently tap or sprinkle the fibers onto your hair, allowing them to intertwine with your own strands. For a targeted application, use the included applicator to direct the fibers precisely where needed. This process can be completed in just a few minutes, making it practical for both daily use and special events.
  • Question: Will Top Secret Hair Thickening Building Fibers wash out easily?

    Answer: Yes, Top Secret Hair Thickening Building Fibers are designed to wash out easily with shampoo. This allows for convenience and flexibility, letting you change your hairstyle or look without any hassle. The fibers adhere to hair strands but are not permanent; just a single wash is all it takes to remove them. This property enables users to enjoy thicker hair one day and return to their natural look the next without any residue.
  • Question: Can Top Secret Hair Thickening Building Fibers be used on all hair types?

    Answer: Absolutely! Top Secret Hair Thickening Building Fibers are suitable for all hair types, including straight, wavy, and curly. Whether fine, thick, or textured, the fibers cling to your natural hair, creating volume and fullness without alteration or damage. This versatility makes it an ideal solution for anyone experiencing thinning hair, regardless of the hairstyle or texture they prefer.
  • Question: Are the fibers safe for colored or treated hair?

    Answer: Yes, Top Secret Hair Thickening Building Fibers are safe to use on colored or chemically treated hair. The natural keratin fibers won't alter your hair color or texture, allowing you to enhance thickness while maintaining your desired look. This is a significant benefit for individuals who wish to hide thinning areas without compromising their hair treatments, as the fibers blend seamlessly and are undetectable.
  • Question: How long do the fibers last once applied?

    Answer: Once applied, Top Secret Hair Thickening Building Fibers can last throughout the day until your next wash. They are resistant to wind, rain, and sweat, providing confidence without worrying about losing volume or coverage. This durability makes them perfect for all-day wear, whether you’re at work, an event, or enjoying time outdoors.
  • Question: Can I use styling products after applying the fibers?

    Answer: Yes, you can use styling products after applying Top Secret Hair Thickening Building Fibers. However, it’s best to style your hair before the fibers to ensure even distribution. If desired, light-hold hairsprays can be applied afterward to set your style without disturbing the fibers. This flexibility allows you to achieve your desired look while adding volume and thickness.
  • Question: Are Top Secret Hair Thickening Building Fibers suitable for both men and women?

    Answer: Yes, Top Secret Hair Thickening Building Fibers are designed for both men and women. Whether you are looking to conceal thinning hair or simply wish to enhance volume, this product caters to all users. Its neutral application makes it versatile for anyone seeking a fuller hairstyle, further promoting confidence and a natural appearance for all hair types.

This ensures that when applied correctly, your hair appears fuller and thicker without anyone noticing you've used a product.
