Thank you for viewing. This is a 6-hour set of Aibou (scalp cooling cap). I purchased it from Ice Japan this April and used it a total of 16 times. The Velcro on the supporter cap shows signs of use. Also, there is some fraying overall due to the Velcro sticking to the fabric. Please see photos 2-4 for details. Since there are 3 supporter caps, please replace the supporter cap from the 4th hour onwards. The cooler box is unused and in a clean condition. (I carried it in a shoulder-style cooler bag) 【Set Contents】 - Cooler box…1 - Cooler box ice packs…6 - Scalp cooling 60-minute ice packs…6 sets - Supporter caps…3 - Outer hat (dial type)…1 - Instruction manual…1 set ⚫︎ All items, including the ice packs, will be stored in the cooler box and shipped in a cardboard box. ⚫︎ The ice packs have been disinfected with alcohol, and the supporter caps and outer hat have been washed. Please note that it takes 3 days for the ice packs to freeze. Regarding the effect of use, hair loss was reduced by about 50%, so I believe scalp cooling was beneficial. Although individual results may vary, I hope this will be helpful for those undergoing treatment that causes hair loss.
