Question: how do you tell the difference between dandruff and dry scalp?
Answer: A dry scalp can cause dandruff, but the two conditions are distinct. Dandruff causes the scalp to flake and may cause visible flakes on clothing or in the hair. In some cases, it is due to a fungal or other scalp infection. Dry scalp, by contrast, occurs when the scalp does not produce or hold enough moisture.
