## Cons

- Feelings of oiliness shortly after application, which may be inconvenient
- Not designed for hair growth or thickening, focuses mainly on scalp comfort
- May require regular use to see long-term benefits; not a quick fix
- Can feel greasy if used immediately after washing hair, requiring a waiting period
- Some users note that increased oiliness might be due to hydration being confused with oiliness
- Might need to wash hair more often if roots become too oily

## Bottom Line

Based on the reviews, this scalp serum is a solid choice for soothing dryness, itchiness, and flakes, especially if you prefer a lightweight, non-greasy formula. However, if you’re concerned about roots feeling oily or greasy, you might want to consider a more oil-free or less frequent application routine. For those seeking both hydration and potential scalp calming, this product is worth trying, but keep in mind it’s not a miracle solution for hair growth or thickening. If you prioritize a less oily experience, you could explore alternatives like: <component-button-product identifierProduct="XYZ123456"></component-button-product>
