Tinea Capitis
Oral treatment is indicated for tinea capitis. “Topicals just don’t really clear this,” Dr. Oboite said. Also, talk to patients and families about preventing reinfection with the dermatophyte that causes this condition. “Make sure we’re cleaning hats, combs, brushes, and pillowcases. That is really important.”
Some patients can develop a widespread rash while on treatment. But in most cases, it’s not an adverse reaction to the medication but rather an indication that the body’s response is revving up, she noted.
Griseofulvin 20 mg/kg/d is one treatment option. Another is terbinafine (using weight-based dosing). A tip with terbinafine is that because the tablet needs to be crushed for a young child, “you can put it in anything, besides applesauce or yogurt with fruit on the bottom, which can be acidic and reduce the effectiveness of the medication,” Dr. Oboite said.
For cases of severe, inflammatory tinea capitis such as a kerion, “I will say you have to hold the hands of these patients, the journey can be long,” she added.
Trichotillomania
Trichotillomania occurs when someone cannot stop pulling their own hair, and in the early phases, it can be confused with alopecia areata. A thorough history and examination of the patient can help distinguish the two conditions. Sometimes a child or teen has a history of anxiety-related behaviors like nail biting that points to trichotillomania. Another tip is to use a dermatoscope to help distinguish hair loss conditions because it avoids having to do as many biopsies in children.
Redirection therapy can work for younger children, and cognitive behavioral therapy (CBT) can help older children with trichotillomania. In response to a question during the Q&A period, Dr. Oboite said psychiatrists or psychologists can perform CBT. If it takes time to get an appointment, there are some CBT apps that can help in the meantime, she said.
“One thing really important is to not blame the child,” Dr. Oboite said. “Most children don’t even know that they’re doing this. This is often not a behavior that is being done on purpose.”
Androgenetic Alopecia
Rarely, children and teenagers can also present with androgenetic alopecia, which Dr. Oboite has successfully treated with topical minoxidil, applied once a day before increasing to twice a day if tolerated. “I will tell them that when they pick it up, it will say ‘you should not use in children.’ But it actually can be used in children safely.”
Low-dose oral minoxidil is another option. Both treatments require a commitment by patients and parents because they are “taking this for a long time.”
Loose Anagen and Uncombable Hair Syndromes
A rare genetic form of hair loss is called loose anagen syndrome. Children with this disorder will have thin hair that is easily pulled out without a lot of force. Their hair appears to typically only grow to a certain length (such as to the nape of the neck) and then stops.
Another genetic hair loss condition is uncombable hair syndrome. It can cause hair to grow out of the scalp in all directions, and as the name suggests, it is almost impossible to comb or brush down. Along with loose anagen syndrome, uncombable hair syndrome tends to improve as the child gets older. “The key point here is telling parents that it can get better with time,” Dr. Oboite said.
