Any treatment recommendations for red tender scalp?

Earlier this year I was examined for hair loss and erythema. Diagnosis was TE and telangiectasiasdue to solar damage. A biopsy was done and LPP ruled out. my GP raised her eyebrows at the derms diagnosis since i have lots of hair. No treatment was suggested, I was just told i shoud wear a hat. however, from time to time, (now) my scalp reddens and hurts in same spots. Anything i can do to relieve the discomfort based on this diagnosis?
