When it comes to hair system bonding, nothing is more important than the cleaning in order to prepare for a new install. Bond Breaker Shampoo breaks down the adhesives, scrubs the skin, and cleans the hair in one step! Saving you lots of time and money. It is great before an install or after removal of a unit to do final cleaning. Keep in mind, most other shampoos will leave residues that will greatly reduce hold times.
