Red light therapy (RLT) is an emerging treatment for psoriasis in general, but research specifically on scalp psoriasis is still very limited. It uses red or near-infrared light from low-power LED sources and works by stimulating cell growth and healing deep within the skin.
One small early study showed 60–100% clearance of plaque psoriasis after 4–5 weeks of RLT — but the sample size was too small to draw broad conclusions. Many MyPsoriasisTeam members have shared positive experiences with RLT for psoriasis overall, including:
- Significant skin clearing within just two weeks
- Reduced inflammation
- Softer skin texture
That said, cost and commitment can be barriers, as some members have noted. For scalp psoriasis specifically, more established light therapy options include UVB phototherapy using a special UV comb, which parts the hair to deliver light directly to the scalp. This is a well-studied and dermatologist-recommended approach.
There are also some risks with RLT to be aware of:
- Misuse can cause burns or irritation
- Skin trauma from burns could trigger the Koebner phenomenon, where new psoriasis plaques develop in the affected area
- Home devices should be used with caution
It's always best to speak with a dermatologist before trying RLT, especially for scalp psoriasis, to find the safest and most effective approach for your situation.
