BosleyMD BOSVolumize Keratin Hair Thickening Fibers — Medium Brown 0.42 oz, Instant Fuller Look, Wind & Sweat Resistant

BosleyMD BOSVolumize Hair Thickening Fibers are lightweight keratin fibers that cling to existing hair to instantly create the appearance of thicker, fuller-looking hair in thinning areas and bald spots.

If you want a quick, non-invasive way to reduce the look of thinning hair, these keratin-based fibers blend with your natural strands and build noticeable volume in seconds. Formulated to mimic human hair and engineered to electrostatically attach to hair shafts, BosleyMD fibers come in a conveniently sized 0.42 oz container and a medium brown shade designed to match common hair tones. The formula is vegan, free of sulfates, parabens and phthalates, and is designed to resist wind and sweat for everyday wear.

How do the fibers attach to my existing hair?

The fibers are made from keratin and carry a negative charge that bonds with the positive charge of natural hair, producing a static-cling effect. This electrostatic attraction enables the particles to wrap around individual strands, creating instant density without adhesives.

• Keratin-based particles mimic human hair texture for seamless blending.
• Negative charge ensures secure attachment to natural strands.
• Lightweight fibers avoid weighing hair down while adding volume.

Will the fibers hold up during a busy day or light activity?

BOSVolumize is formulated to be wind and sweat resistant for daily life, offering reliable coverage through routine activity. For best endurance, apply to dry hair and use a setting spray or the recommended fixer to lock fibers in place.

• Wind- and sweat-resistant finish for active days.
• Pairs well with styling products designed for hold.
• Best results when applied to dry, clean hair for maximum adhesion.

How quickly will I see results and how is it removed?

Results are immediate — fibers attach as soon as they contact hair, filling in sparse areas and camouflaging thinning spots. Removal is simple: wash hair with your regular shampoo; fibers rinse out because they are designed for temporary use.

• Instant visual thickening upon application.
• Temporary coverage that washes out with regular shampooing.
• Safe to use alongside other hair-care routines and post-procedure maintenance.

Can these fibers be used after hair restoration treatments?

BOSVolumize is commonly used as a temporary cover-up following procedures or to complement existing treatment results. Because the fibers sit on existing hair rather than penetrate the scalp, they are suitable for enhancing visible density while you recover or wait for longer-term results.

• Ideal for temporarily improving appearance after procedures.
• Non-invasive option to boost visible fullness between treatments.
• Works with a range of haircare and styling regimens recommended by professionals.

Who is this for: BosleyMD BOSVolumize Hair Thickening Fibers are aimed at men and women seeking an immediate cosmetic lift for fine, low-density or thinning hair without a prescription. It suits people who want an easy daily solution for concealing sparse areas, anyone preparing for public-facing moments, and those looking for a non-permanent way to enhance the look of density after hair-restoration procedures.
