Dear Adena- braun. It is certainly frustrating to have an itchy and flaky scalp. You are likely to have eczema/ seborrhoeic dermatitis of  the scalp. They usually present with irritated, inflammed, red, itchy scalp.

You might wish to consider a change of shampoo to something gentle such as head and shoulder wash. Alternatively you may wish to consult a doctor and prescription medications such as anti fungal shampoo eg Pristine shampoo is useful for scalp eczema. Application of topical steroids such as clobetasol/ dermasone scalp lotion will also be useful for your condition. Lastly anti histamines such as cetirizine helps to reduce the itch.

You might find staying in air conditioned environment useful as hot and humid environment tends to trigger eczema and take note of any hair gel/ wax/ dye/ wash you apply to your hair/ scalp that could have irritated your scalp.

Hope this helps!
