Please seek a formal diagnosis, without that anything we say is amateur guesswork. Any self treatment based on a self diagnosis can do more harm than good - all the things you have tried are capable of further damaging the skin's barrier function.
Whilst you are organising an appointment with your family doctor or a dermatologist, DO NOT scratch use cold compresses instead, do not heat your scalp wash in cool water, no long plops or towel turbans. Both heat and scratching can trigger histamine release, cool should provide temporary relief but is in no way a 'cure'.
Also review your diet and make it as micronutrient dense and anti inflammatory as possible, particularly look at your intake of essential fatty acids from oily fish and your intake of sugar/ white refined carbs. This can alter the composition of your sebum, strengthen your skin barrier, calm any inappropriate immune responses and reduce systemic inflammation all of which are implicated in the most common scalp disorders.
All products contain ingredients which can irritate or cause allergic reactions given the right set of circumstances, Tresemme Naturals is nothing special in that regard. Irritations and allergies can arise at any time, they do not need to be to a new product or ingredient. Even chlorine in tap water can be a problem where there is an underlying dermatological disorder.
