Does Bright lights shampoo work to brighten white lambs???

Shows just around the corner and idk if brightlights will help my white lambsDoes Bright lights shampoo work to brighten white lambs???
There is a kind of shampoo available from veterinarians called ';Pearlyte'; and it is blue. It is made by ';DVM';





I use it on my horse who has long white mane and it really cleans it up.





I suppose any shampoo with a blueing agent will help.
