FAQ
Q1. Do hair building fibers really work?
Ans: Yes, hair building fibers work instantly by using static electricity to bond natural keratin particles to your existing hair strands. This creates immediate volume and density, effectively concealing thinning spots and visible scalp until your next shampoo.
Q2. Can both men and women use this hair filler?
Ans: Absolutely. This product is formulated as a gender-neutral cosmetic solution that works effectively on all hair types, lengths, and styles for anyone experiencing fine or thinning hair.
Q3. Is the formula safe to use daily?
Ans: Yes, the building fibers are made from natural keratin protein and are paraben-free, making them safe for daily use. They do not clog pores or interfere with normal hair growth treatments.
Q4. Is Top Secret Hair Thickening Fibers available as an authentic import in India?
Ans: Yes, you can purchase authentic Top Secret products in India through Rudra Retails. We source our inventory directly from the USA, ensuring Indian consumers receive genuine, high-quality international personal care items.
Q5. How do you remove the fibers from your hair?
Ans: The fibers stay securely in place against sweat and wind, but they are easily washed out. Simply use your regular shampoo and warm water to completely clean the product from your hair and scalp.
