Scaly scalp: causes and treatments

Scaly scalp: the causes

Scales are thin strips of skin that detach from the epidermis. This is called desquamation, which can affect all parts of the body such as the face or scalp.

When you notice dander on the scalp, the causes may be:

• external factors such as pollution, bad hair products, hair colour, straightener or hot hair dryer…
• internal factors such as stress, fatigue, hormonal disorders, health problems, etc.;
• skin disease such as psoriasis or seborrheic dermatitis.

Dandruff has the appearance of dandruff that is also called «pityriasis» when it is on the scalp. They usually appear on dry or oily scalps.

Hormonal disturbances can promote their appearance. A scaly scalp is especially common in adolescence.

2 types of dandruff

There are 2 types of dandruff:

• dry dandruff, which are small white scales that come off easily when you shake your hair (they fall on your shoulders and clothes);
• oily dandruff that collects on the roots and lengths and causes itching of the scalp.

Dandruff can also be caused by the proliferation of a yeast Malassezia which is a common fungus. This micro-organism causes too fast a cell renewal that leads to dandruff.

If left untreated, these dandruff can promote hair loss, loss of hair density and skin irritation.

Zinc deficiency, the consequences on the skin

Zinc deficiency is manifested by several symptoms such as:

• skin problems such as acne, a dull complexion, dry, scaly skin and difficulty healing wounds;
• hair loss;
• brittle nails;
• Immune weakness and fatigue
• vision problems;
• impaired brain abilities (lack of concentration, memory, mood disorders, etc.).

Supplementing with zinc is sometimes useful to reduce acne pimples and regain beautiful skin. This becomes necessary when your health suffers.

Only a blood test can tell you if you have zinc deficiencies. If you suspect a deficiency, we advise you to talk to your doctor.

Apply beauty products rich in zinc

Effective against oily skin and oily hair, zinc regulates the overproduction of sebum. This liquid composed of water and lipids protects the skin barrier.

Produced by the sebaceous glands, it is necessary for the epidermis. But generated in excess, it clogs the pores and causes pimples.

To combat acne, you can incorporate zinc-enriched beauty products into your skincare routine.
