Toppik Colored Hair Thickener, Temporary Hair Color Spray for Root Touchup with Hair Thickening Fibers, 5.1 oz

Customers find the hair thickener effective, particularly in the crown area, and appreciate its coverage of thinning areas. The sprayability receives mixed feedback - while some say it's even, others find it hard to apply in certain areas. Moreover, the color quality is problematic, with customers noting it's lighter than expected and runs when it rains. Additionally, the product causes staining on clothes and pillows, and customers report it makes hair feel greasy and sticky, while also being messy to apply.
