Washing your hair with a harsh shampoo or using a lot of chemicals on your hair can sometimes irritate your scalp and cause it to flake. This inflammation leads to overproduction of skin cells, which leads to flaking. If this is the cause, the flakes are usually small, and you may also have dry skin on other parts of your body.
What do large scales of dandruff mean?
If you have stubborn flakes that aren’t easy to remove with an anti-dandruff shampoo, you may need to see a certified dermatologist or a trichologist. Scalp dandruff and psoriasis can look very similar as they both create skin flakes in and under the hair. However, psoriasis often has more severe symptoms such as plaques, bleeding, and itchy or burning skin. Psoriasis can affect any area of the scalp and typically appears as thick, inflamed, and reddish patches or silvery-white scales.
