Hair Types & Frequency of Shampooing

Frequent shampooing would be effective in preventing the build-up of dirt, sweat, and oils and it would help in stopping the follicles from getting clogged thus, preventing itching and flaking and helping your hair to attain optimum growth rate.

Heat Styling & Frequency of Shampooing
No matter what your hair type or texture is you need to follow a different hair regimen if you are addicted to heat styling like curling or straightening.
