thank you for your query.
There are many contributing factors to the development of a tender scalp..
1. dry skin
2.overly tight hairstyles.
3.infections like ringworm and acne
your symptoms point towards ring worm infection
or tinea capitis
In some cases, a fungal infection
may be at the root of tender scalp issues. it is marked by reddened sections of scalp; round, scaly patches; itching; and scalp soreness or tenderness.
Some people even develop black dots and sores that fill with pus when they have this condition.
* Treating this condition with antifungal drugs, which are typically taken orally, will often relieve the symptoms of tinea capitis, including tender scalp.
*you can use anti-fungal shampoos too
*application of anti fungal agents such as ketkonazole on the affected part will also help
wishing you good health
