I have an itchy scalp from time to time and it was AWFUL. Everything I seemed to use made it worse. (I guess the problem stemmed from allergens and build-up.)
I clarified more often and that seemed to help. I would DC or use hot oil treatments and apply a pomade. I love Qhemet Biologics
Tea Tree & Grapeseed Therapeutic Pomade. Since then, no horrendous itch. AT ALL. It feels soooo good
on my scalp. This is definitely going to be a staple for me. It's gentle AND it works.
Slightly OT: My BFF has SEVERE eczema. She went to the doc and found that she had some pretty serious food allergies. (Shellfish/Milk/Nuts) So I suggest taking the time to create a journal of food and products as well as the mild to the most severe flare-ups occur. You may find that the culprit could be food or product induced.
I did this with my fibromyalgia to see what I was responding to.
