BosleyMD Hair Thickening Fibers for Thinning Hair — Medium Brown 0.42 oz, Instant Natural Fullness

If you want immediate, natural-looking fullness without salon time, BosleyMD BOSVolumize delivers lightweight keratin fibers engineered to bond to your hair and camouflage low-density zones. The fibers mimic human hair and use electrostatic attraction to stick to your natural strands for an undetectable boost in volume. This 0.42 oz sachet in Medium Brown is formulated to be vegan, sulfate- and paraben-free, and designed for easy daily application and styling compatibility.

How do these fibers attach to my hair and stay put?

BOSVolumize fibers are negatively charged keratin particles that cling to the positively charged surface of your natural hair, creating a static-grip for instant coverage. The result is a quick increase in visible density that resists mild wind and perspiration when applied correctly. They do not chemically alter your hair and can be removed with regular shampooing.

• Electrostatic bonding to individual hair shafts for natural hold
• Lightweight fibers avoid weighing hair down
• Wind- and sweat-resistant under normal daily conditions
• Easily washed out with shampoo

Will BOSVolumize look natural in different lighting and during activity?

The keratin fibers are designed to match hair texture and reflect light similarly to natural strands, reducing shine differences that expose concealment. When blended into the root area and styled, the fibers diffuse thinning zones and maintain a realistic appearance in photos and daylight. For active days, pair with a light-hold spray for added longevity.

• Medium Brown shade optimized for natural color blending
• Fibers mimic hair texture to avoid unnatural shine
• Compatible with styling products and light hairsprays
• Suitable for photos and routine activities

How should I apply and remove the BosleyMD thickening fibers?

Application is simple: style hair, sprinkle or shake fibers over thinning areas, then lightly pat or comb to distribute. For precision, apply a small amount at a time and build coverage gradually until the desired thickness is reached. Removal is straightforward—wash hair with your regular shampoo to clear fibers completely.

• Apply to dry, styled hair for best adhesion
• Use small amounts and build coverage incrementally
• Secure with a light-hold spray if needed for extra resistance
• Removes fully with regular shampooing

Are these fibers safe for sensitive scalps and post-procedure use?

BOSVolumize is formulated without sulfates, parabens, phthalates, and is vegan; it was developed to be gentle on scalp and hair. BosleyMD notes these fibers are often used as a temporary cover-up following procedures to enhance perceived density, but you should follow any post-procedure care instructions from your provider. They are not a replacement for medical treatment or hair restoration procedures.

• Vegan and free from harsh chemicals
• No animal testing—BosleyMD Pro recommended
• Commonly used for temporary density improvement after procedures
• Follow clinician guidance for post-procedure application

Who is this for? BOSVolumize Hair Thickening Fibers are aimed at men and women seeking immediate cosmetic coverage of thinning patches, low-density areas, or post-procedure support. Ideal for users who want a non-permanent, easy-to-use solution that blends with natural hair and works with everyday styling routines. If you need long-term medical treatment for hair loss, consult a hair restoration specialist—BosleyMD is recognized for clinical hair care and can guide next steps.
