Ankylosing Spondylitis and Psoriasis

My daughter was diagnosed with AK about 5 years ago. She has been on Humira since her diagnosis and was doing great. Unfortunately, during the last few years the Humira triggered Psoriasis and it started out being manageable but has gotten progressively worse -mostly on her scalp. (Humira is often used to treat Psoriasis - but in rare cases can actually tigger it.) She was just changed from Humira to Cosentyx in January. Her back is still doing great but she has been losing a significant amount of hair in patches on the top of her head. We just started Otezla in addition to the Cosentyx. Her rheumatologist and dermatologist communicate and are on the same page. Has anyone else experienced this and has anything worked on the Psoriasis?? Shampoos? Nutrafol? diet? We are open to suggestions.
