Final answer:
It is recommended to gently wash bonded hair using sulfate-free shampoo. Hot water should be avoided as it can weaken the bond. Gentle washing helps prevent damage to the hair extensions.
Step-by-step explanation:
Gently washing bonded hair with sulfate-free shampoo is recommended. Sulfate-free shampoos are milder and less likely to damage the bond of the hair extensions. Hot water should be avoided as it can weaken the bond and cause the extensions to loosen. It is important to be gentle when washing to prevent tangling or pulling on the bonds.
