A scab on your scalp generally isn’t a big concern; when it appears in the same area more than once, it can be troubling. You might try using shampoo, creams or leaving it alone, but it can still come back and get worse.
No matter if you are curious, embarrassed or in discomfort, you’re not alone. People can develop recurring scalp scabs, which may indicate a mild or serious underlying cause.
A recurring scab on the scalp in the same spot can help you find an existing problem, whether it’s a skin disorder, an infection or a reaction to something you’re using. This guide will explore the reasons and solutions to help you stop worrying and start healing.
What Is a Recurring Scab?
A recurring scab is a wound or lesion that heals but reappears many times in the same place. If your rash is itchy and does not improve quickly, it could indicate serious inflammation, an infection or irritation.
Often, the back and forth healing and reopening of the scabs occur due to scratching, activities that apply pressure and certain skin problems. It has the following common signs:
| Symptom | Description |
|---|---|
| Itching | Persistent urge to scratch the area. |
| Oozing Or Bleeding | Especially if picked or irritated. |
| Flaky Or Crusty Skin | Can resemble dandruff but is more persistent. |
| Hair Loss | Hair may fall out in the affected area. |

Why Do I Have Crusty Scabs On My Scalp?
Usually, crusty scabs come from dried blood, lymph fluid or pus caused by scratching or picking at a wound. Crusting could also occur with conditions such as psoriasis, eczema or fungal infections. The repeated damage prevents full healing, causing scabs on the scalp in the same spot.
