How to Treat Scalp Psoriasis with Home Phototherapy
Scalp psoriasis is one of the most common—and most challenging—forms of psoriasis to manage. The thick scale, intense itching, and inflammation that occur along the hairline and scalp can significantly impact daily life, especially when over-the-counter shampoos and creams fall short.
The good news? Home phototherapy is a safe, clinically proven way to treat scalp psoriasis effectively—right from the comfort of your home.
What Is Scalp Psoriasis?
Scalp psoriasis is a chronic autoimmune condition that causes the skin cells on the scalp to grow too quickly, leading to:
- Flaking and silvery scales
- Red or inflamed patches
- Itching, burning, or soreness
- Hair shedding due to scratching or inflammation
It can appear in isolated patches or spread across the entire scalp and often extends to the forehead, neck, or ears.
Why Is Scalp Psoriasis Hard to Treat?
Treating the scalp is difficult for a few key reasons:
- Hair blocks topical treatments and light
- Many products are greasy or hard to apply
- Scratching or buildup can worsen inflammation
- Shampoos may only provide short-term relief
Because of this, many dermatologists recommend phototherapy—a form of controlled light therapy that penetrates the skin and reduces inflammation.
How Phototherapy Works for Scalp Psoriasis
Phototherapy, also known as light therapy, uses narrowband UVB light to:
- Slow the overproduction of skin cells
- Reduce redness and itchiness
- Clear plaques over time
- Support longer periods of remission
It’s the same type of light naturally found in sunlight—without the harmful UVA rays. And unlike steroids or biologics, it doesn’t thin the skin or suppress the immune system.
Home Phototherapy for the Scalp
While in-office phototherapy is effective, frequent clinic visits can be time-consuming and costly. That’s where home phototherapy comes in. Phothera’s at-home devices, available by prescription, bring dermatology-grade treatment to your fingertips.
The Phothera Advantage:
- Safe, targeted light therapy guided by your provider
- Customizable comb attachments designed to part the hair and deliver light directly to the scalp
- Portable, easy-to-use devices like the Phothera 100 or 100XL
- Cost-effective long-term solution for chronic conditions
Step-by-Step: How to Use Home Phototherapy for Scalp Psoriasis
- Consult Your Dermatologist
First, your provider will determine if home phototherapy is right for you and prescribe a device tailored to your needs. - Receive and Set Up Your Device
Your Phothera device will arrive with clear instructions and treatment guidance. Each unit comes with a scalp comb attachment to help deliver light to the scalp. - Part Hair for Direct Light Exposure
Use the included comb to part the hair during treatment. This ensures the UVB light reaches the skin—not just the hair. - Follow Your Treatment Schedule
Most treatments are 2–3 times per week, lasting only a few minutes. Your provider will adjust the dose and schedule based on your progress. - Track Your Progress
With regular use, you may begin seeing improvement within 4–6 weeks, with further clearing after.
