ULTRAfiller+ Hair Thickening Spray by Kao USA

Description

Product Overview

The ULTRAfiller+ Hair Thickening Spray is a professional‑grade volumizing solution designed to transform fine, limp strands into a fuller, more resilient mane. Housed in a compact 5.98 x 2.17 x 1.26‑inch bottle weighing just 6.38 ounces, the spray is engineered for precise application and travel‑friendly convenience. Formulated by Kao USA Inc., the product carries the model number 29141 and is identified by UPC 717226291418 and ASIN B0CK8H4MPN. Its core ingredients—biotin and hyaluronic acid—work synergistically to increase hair shaft diameter, improve moisture retention, and create a protective barrier against thermal styling tools. The result is a visible 200% increase in overall thickness, a lightweight feel, and a flexible hold that lasts throughout the day.

Usage

Designed for daily use, the spray is ideal for anyone seeking instant volume before blow‑drying, flat‑ironing, or curling. Apply to damp hair, focusing on the roots and mid‑lengths, then style as usual. The heat‑protective formula allows you to safely use high‑temperature tools up to 450°F without compromising hair integrity. Perfect for professional salons, at‑home styling routines, or on‑the‑go touch‑ups, the spray works equally well on straight, wavy, or lightly curly textures. For best results, pair with the ULTRAfiller+ shampoo and conditioner to maintain the volumizing effect and prolong moisture balance.
