and I am really worried about the itching and odor!

There is a possibility that build up has accumulated on your scalp. Build up can cause your scalp and hair to get oily very quickly.

Regarding itching and odor…

The number of the sebaceous glands on the scalp are about double of T zone on the face. The sebaceous glands on the scalp are second most secreted oil after the palms and soles of the feet. When sebum becomes unsaturated fatty acid on the scalp, it can irritate the scalp causing itching and odor due to inflammation.

We recommend the use of NEKKO Pre Cleanser and Head spa Shampoo to remove the build up from the scalp and pores and to help with any recurring problems you may have.
