(Sullivan Supply) Sullivan's Hair Shedding Comb has a large 4” wide head covers more area. Rounded, stainless steel teeth gently penetrate deep into the hair coat, removing the old dead hair and leaving the healthy hair unharmed. Simply pull the shedding comb through the hair coat in the direction you are training the hair before washing/rinsing. Repeat daily until shedding is complete. It’s simple, effective and saves hours. Always remember...the faster the dead hair is shed out, the quicker new healthy hair will arrive.
