If I was to treat my scalp with an oil or butter I'd use something lower in oleic acid (irritant) and higher in stearic and/ or palmitic acids and/ or cholesterol (all strengthen the skin barrier). Unrefined west African shea and lanolin are lovely for skin health, thick tho so would dilute them down/ soften with a lighter oil, perhaps borage for the GLA or whip up some shea-aloe butter. Egg lecithin aids production of ceramides which strengthen skin and hair.
