What Mistakes Should You Avoid When Using Hair Oils for Growth?
When using hair oils for growth, there are several common mistakes to avoid to ensure optimal results.

- Neglecting to Patch Test: Skipping the patch test before using a new hair oil can lead to allergic reactions or irritation. It’s important to test a small amount on your skin to check for any adverse reactions before applying it more broadly.
- Inconsistent Application: Not using hair oil regularly can significantly reduce its effectiveness. Consistency is key; applying hair oil a few times a week can help maintain scalp health and promote hair growth.
