Unfortunately, this happens to a few people and when it does, I generally tell the patient to wait out a full hair cycle which is usually 3 years or so. You can ask your hair stylist for way to reduce the curl and texture of your hair as there are many products sold that might help you while you wait out the 3 year cycle.
To keep the integrity and genetic structure of the hair, one must make sure that every precaution is taken in handling the grafts during the procedure. If the grafts are not handled properly in every step of the procedure, then the texture or the structure of the hair may be compromised. Sometimes, initially when the hair starts to grow in it looks a bit different. However overtime it returns to its original texture. If it doesn't then the grafts may have been handled improperly. You need to be patient a few more months and then follow up with your doctor.
