Q: How do I apply Sevich 100g Hair Building Fibers for the most natural result?
A: Start with clean, dehydrated hair. Lightly shake fibers over thinning areas, then pat to settle. For extra hold, mist a light hairspray before and after application. Style gently with a wide-tooth comb or fingers—avoid vigorous brushing.

Q: How do I choose the right shade—and can I blend colors?
A: Match the fibers to your root color. If you’re between shades, opt for a slightly darker tone for added depth. You can mix two shades (e.g., dark brown and black) directly on the hair to create a custom blend for highlights or lowlights.

Q: Will the fibers stay put in wind, sweat, or light rain?
A: Yes—electrostatic binding helps fibers cling to hair. A light hairspray significantly enhances durability through sweat, humidity, and light rain. For heavy rain or swimming, reapply afterward.

Q: Are the fibers safe for daily use and sensitive scalps?
A: The keratin-based formula is non-irritating for most users and washes out with regular shampoo. If you’re highly sensitive, do a patch test and avoid inhaling the powder during application.

Q: What's the difference between the 100g refill and a standard bottle with applicator?
A: The 100g pack is a long-lasting refill meant to top up your existing shaker or precision applicator (spray nozzle). Using an applicator helps target hairlines, part lines, and more minor spots more precisely while reducing waste.
