5. Head Lice
Head lice are tiny insects that feed on blood from the scalp.
Although they are most common in school-aged children, adults can also become infected.
Common signs include:
- Severe itching
- Feeling of movement on the scalp
- Small white eggs (nits) attached to hair
- Tiny insects visible near the scalp
Special medicated treatments are usually effective.
6. Fungal Infections
Ringworm of the scalp (tinea capitis) is a fungal infection that can cause:
- Itching
- Round bald patches
- Scaling
- Broken hairs
- Redness
Unlike dandruff, fungal infections generally require prescription oral antifungal medication.
7. Product Build-Up
Using large amounts of dry shampoo, hair sprays, gels, or oils without washing regularly may lead to residue accumulation.
This buildup can clog hair follicles and irritate the scalp.
Clarifying shampoos used occasionally may help remove excess residue.
When Should You See a Doctor?
While many cases improve with proper scalp care, you should seek medical advice if:
- Itching lasts longer than two weeks
- Symptoms become severe
- You notice hair loss
- There is bleeding, swelling, or pus
- Home treatments do not help
- The rash spreads beyond the scalp
A dermatologist can identify the underlying cause and recommend the most appropriate treatment.
