Final answer:
The main difference between dry scalp and dandruff is the underlying cause. Dry scalp is caused by lack of moisture, while dandruff is caused by a yeast-like fungus. Treatment options also differ, with moisturizing for dry scalp and anti-dandruff shampoos for dandruff.
Step-by-step explanation:
The main difference between dry scalp and dandruff is the underlying cause of the condition. Dry scalp occurs when the skin on the scalp lacks moisture, leading to itchiness and flaking. On the other hand, dandruff is a common scalp condition caused by the overgrowth of a yeast-like fungus called Malassezia.
One way to differentiate between dry scalp and dandruff is by looking at the appearance of the flakes. Dry scalp flakes are often smaller and less oily, whereas dandruff flakes are larger, greasier, and may be yellowish in color.
To treat dry scalp, it is important to moisturize the scalp regularly using a gentle, hydrating shampoo and conditioner. In the case of dandruff, specialized anti-dandruff shampoos containing ingredients like zinc pyrithione, ketoconazole, or selenium sulfide can help reduce the fungus and alleviate symptoms.
