2. Psoriasis
Scalp psoriasis is an autoimmune condition that speeds up skin cell production.
Instead of shedding normally, skin cells build up into thick, silvery scales that may itch, crack, or become sore.
Symptoms may include:
- Thick red patches
- Silver-colored scales
- Dry or cracked skin
- Burning or itching
Treatment may involve prescription shampoos, topical corticosteroids, or other medications recommended by a healthcare provider.
3. Dry Scalp
Sometimes the simplest explanation is dry skin.
Cold weather, frequent shampooing, harsh hair products, or dehydration can strip the scalp of its natural oils.
Signs include:
- Small dry flakes
- Tightness
- Mild itching
- Rough scalp texture
Using gentle moisturizing shampoos and avoiding overly hot water may help restore moisture.
4. Allergic Reactions
Hair dyes, shampoos, conditioners, styling products, and fragrances may trigger contact dermatitis.
The scalp becomes irritated after exposure to an ingredient your immune system reacts to.
Symptoms often include:
- Intense itching
- Redness
- Swelling
- Rash
- Burning sensation
Stopping the product usually helps, although severe reactions may require medical treatment.
