Specifications, review intelligence and safety
- • MORE THAN TWICE THE FIBER OF LEADING BRANDS: While leading brands give you 12 grams per bottle, HAIR MAXER gives you a full 27 grams, more than double the coverage at the same price. That means fewer refills, a longer lasting supply, and more fiber per application, clearly printed on every bottle so you always know what you're getting.
- • INSTANT UNDETECTABLE FULLNESS IN UNDER 30 SECONDS: HAIR MAXER uses premium keratin protein fibers that bond to existing hair strands via natural static charge, instantly creating the appearance of thicker, denser, fuller hair. The fibers blend seamlessly into your natural hair, with no clumping, no patchiness, no shine, and no one will ever know you're using them.
- • STAYS PUT ALL DAY THROUGH WIND, SWEAT AND HUMIDITY: Once applied, HAIR MAXER locks in and holds through your entire day. It is wind resistant, sweat resistant, and light activity proof. Fibers won't transfer onto clothing, collars, or pillowcases, and wash out completely with normal shampoo, leaving no residue and no staining every time.
- • WORKS FOR MEN AND WOMEN ON ALL HAIR TYPES: Whether you're covering a receding hairline, thinning crown, visible part, or postpartum shedding, HAIR MAXER delivers natural looking coverage that works on straight, wavy, curly, and coily hair. It is compatible with all styling products and safe for color treated and chemically processed hair.
- • PRECISION APPLICATOR FOR A MESS FREE, TRAVEL READY EXPERIENCE: Our precision tip dispenser gives you controlled, targeted application with zero powder clouds and zero countertop mess. The secure snap lock cap prevents spills in your bag, gym kit, or luggage, and each 27 gram bottle provides weeks of daily use, one of the best values per gram in the entire hair fiber category.
