Applying hair oil the morning after using Dermadew hair serum at night is generally safe.

• Hair serum and oil serve different purposes: Serums often target specific scalp or hair issues like dryness or damage, while oils provide nourishment and moisture.

• Allow time for absorption: Using the serum at night gives it time to absorb and work effectively. Applying oil the next morning won't interfere with this process.

• Consider your hair type: If your hair tends to get oily quickly, you might want to use a light amount of oil or focus on the ends rather than the scalp.

• Patch test if unsure: If you notice any irritation or heaviness, adjust the amount or frequency accordingly.

In summary, you can apply hair oil the next morning after using Dermadew hair serum at night without concern, as long as you monitor how your hair responds and adjust usage to your comfort and hair needs. For personalized advice, consulting a dermatologist or trichologist (hair specialist) is recommended.
