My niece hair has easy breakage. How can I strengthen her hair?

First, make sure to only comb her hair when it is wet with tons of conditioner in it. Use a wide tooth comb or your fingers to detangle her hair in sections. It may also be time for a trim! Hair is easier to care for when the ends aren't frayed or split. 
Hair that is dry and over manipulated can be susceptible to a lot of breakage. Make sure that hair is moisturized regularly and that it is detangled/combed gently using fingers or a wide tooth comb as atx_eve mentioned. Also, hairstyles that pull tightly on the scalp can cause breakage as well.
