Follow the instructions below to get the most out of your therapy for scalp psoriasis: 

• Avoid scratching your scalp. We understand how itchy scalp psoriasis can be; however, scratching can aggravate psoriasis. Scratching the scalp may result in bleeding and hair loss.
• Treat the psoriasis to relieve the itching. The itch will go away after the psoriasis is gone. If you can't wait that long, notify your dermatologist about unbearable symptoms and follow their recommendations for relief.
• Shampoo with care. It may seem like rubbing while shampooing your hair and scalp is the best option, but it isn't. Scrubbing, rubbing, and scratching your scalp can aggravate psoriasis. 
• Carefully remove the scale. You must loosen and eliminate the scale on your scalp to treat scalp psoriasis. Proceed with caution. Psoriasis flare-ups and hair loss can be caused by picking. 
• A scale softener is recommended by dermatologists. The thick, obstinate patches of psoriasis can be softened with a salicylic acid-based scale softener. Softening these patches also improves the effectiveness of psoriasis medication. Always move your hair out of the way when applying medicine to your scalp. This ensures that the drug is applied to your scalp rather than your hair.
• Try not to get too worked up. A psoriasis flare-up is a stressful situation. However, being anxious can make things worse. Psoriasis can be aggravated by stress. Hair loss is a common side effect of stress. Finding ways to relax can be really beneficial.
