The Havana Hair is seriously dry and drying to your natural hair. Even though it's admirable to have this 4c style, it's nowhere near the softness of anyone's 4c hair. My 4c hair is touchable--this 4c fiber absolutely is not.
I wrote to Fingercomber about this and they responded with "use some shea butter." Trust me, this fiber WILL NOT absorb shea butter--it does nothing to make it softer. Hair like this will CUT into your real hair where it meets it and abrade it with every movement.
I don't believe this is a black-owned business/website because a black-owned business would be more diligent and pro-active about providing a service that would help--not harm--black hair.
