Cornetto is designed to blend in with naturally darker hair that is dyed blonde. Hair is always naturally darker at the roots, so the Ombre is designed to help blend that in. Cornetto is suitable for blondes with naturally dark-medium brown roots, or root shadowed hair colours. It’s the darkest level ombre blonde.
PONIME is made from high quality real human hair, so treatment won’t differ much from yours. There is no oil producing scalp, so it will need less washing. Most products are water soluble as well, so shampoo is not always necessary. Just a rinse and condition.
