OK, so not the sexiest subject in the world. But it's important. Let's chat about scalp health. Study after study shows that keeping your scalp healthy promotes healthy hair growth; some even claim that it will help hair regrowth.
If your life is busy like ours, scalp health is the last thing on our mind. It often goes untended until you're having a heart-to-heart with a friend and you spot the telltale white bits in the hair.
Dandruff—what is it?
Excerpt from our beloved NHS.co.uk. For full article, click here.
Your skin constantly produces new skin cells and sheds old cells to stay healthy. Dandruff can occur when this cycle of skin renewal speeds up.
This leads to patches of dead skin forming on the scalp that come away into the hair.
A flaky scalp can be the result of:
- seborrhoeic dermatitis – a common skin condition associated with an overgrowth of yeast on the skin, which can cause the scalp, face and other areas of the body to become scaly, itchy and red; in babies it's called cradle cap
- tinea capitis – a fungal infection of the scalp, also called scalp ringworm
- eczema – a common skin condition that causes the skin to become dry, red, flaky and very itchy
- allergic contact dermatitis – a reaction to products used on the scalp, such as hair dye, hairspray, hair gel or mousse
- psoriasis – a skin condition that causes red, flaky, crusty patches of skin covered with silvery scales
Dandruff isn't caused by poor hygiene, although it may be more obvious if you don't wash your hair regularly. Stress and cold weather may also make it worse.
