Eat well. Shampoos and conditioners can only do so much.
The bouncing, beautiful hair you want only comes from a well-nourished body with a healthy scalp. Change your diet to include non-refined foods, plenty of fruits and vegetables and drink lots of water to maintain a healthy body which will produce healthy hair.
The other thing that helps is to keep the scalp well-nourished with a free-flowing blood supply. Everytime you shampoo your hair, give your scalp a long massage. At the end of the massage, you should be able to freely move your scalp slightly. This relieves the pressure on the pores and blood vessels allowing the vessels to adequately nourish pores to aid in healthy hair.
