The first time you use Sevich 100g Hair Building Fibers, you will probably laugh at how easy it is. Shake. Pat. Done. In under a minute, the keratin fibers bond electrostatically to your existing hair — filling in thinning patches, adding density to sparse sections, and making the scalp look uniformly full. The 100g refill size means you will have enough to work with for weeks before you need to reorder.
The kind of result you would spend an hour at the salon trying to achieve. Takes about forty seconds at home.

Why Choose Sevich 100g Hair Building Fibers
Keratin fibers work because they are structurally similar to the protein your own hair is made of. When applied to the scalp and hair roots, they interlock with your existing hair using static electricity, creating a continuous-looking mass that is difficult to distinguish from what grows naturally. The 100g size is Sevich's refill format: significantly larger than a standard travel bottle, and designed to last 4–6 weeks of daily use. Ten shades means there is almost always a match — or blend two adjacent shades directly on the hair to create a natural gradient that matches highlighted or ombre styles.

How to Use
- Style and dry hair completely — fibers work on dry hair only
- Mist a light hairspray over the thinning area before applying for improved hold
- Shake fibers evenly over the target area from 2–4 inches away
- Pat gently with fingertips to settle fibers into the hair
- Style with fingers or a wide-tooth comb — avoid vigorous brushing
- Seal with another light hairspray mist for all-day wear
- Wash out completely with regular shampoo and water
Care & Storage
- Store in a cool, dry place with lid tightly closed — humidity causes clumping
- Do not apply to wet or damp hair; wait until completely dry
- Avoid inhaling the powder during application — apply in a well-ventilated area
- Safe for color-treated hair; patch test if you have a sensitive scalp
- Wash pillowcase regularly — fibers wash out easily in the laundry
