I love both..Deva has more protein and glycerin in it.so if u are either protein or glycerin sensitive u won't b able to get gr8 results with them.The Shea moisture products are more moisturising n has tonnes of oils in it.. U can either use them as sealers , moisturisers or curl enhancers..they don't have enough hold to be used alone as a styler.. Hope dis helps!
