An occasional hair treatment will nourish and groom hair especially if the hair is frequently washed and exposed to sun, wind and salt or chlorinated water. Hot oil treatment is the best way to treat dry, thiin, straw like, brittle, dandruff and split end. Hot oil treatment using Natural ingredients like Essential oils diluted in Carrier Oils or even Pure Butters will work wonder for it. Even oily hair needs to be treated for balanced sebum production, better circulation, and deep cleaning of scalp.
