Condition of your own hair prior to braiding.
I would recommend the following before you start braiding your hair, wash it with a shampoo for oily hair and condition it with a conditioner for dry hair.
Use a good quality synthetic hair for braiding your hair and request that the braids are not too thick or too tight.
I would also purchase a good quality leave in spray conditioner like V05 miracle mist (non greasy). Do no use any oils or hairspray on your head. Twice a week gently wash your hair with the shampoo for oily hair, towel wrap and then leave to dry normally.
Braiding hair was used several hundred of years ago to keep hair neat, free from head lice and manageability in hot weather. It is usually uncommon to be experiencing odour and smells just after two days, this would normally follow several weeks later if hair had not been tended to.
