Whether oily hair is "good" depends on the degree of oiliness and its effects on your hair and scalp. Having some oil is actually necessary for healthy hair.
The Upside of Oily Hair
According to research, healthy hair needs oil. Oil helps to:
- Keep hair moisturized: Natural oils prevent dryness and breakage.
- Provide shine: Oil gives hair a healthy, glossy appearance.
- Protect the scalp: Oil acts as a barrier against irritants.
The Downside of Too Much Oily Hair
The reference states that too much oil can cause issues. These include:
- Greasy appearance: Excess oil makes hair look dirty and unkempt.
- Brittle hair: While seemingly contradictory, too much oil can trap dirt and prevent moisture absorption, leading to brittleness over time.
- Scalp issues: Excessive oil can contribute to conditions like seborrheic dermatitis.
Conclusion
Having oily hair does not necessarily mean your hair or scalp is unhealthy. It only becomes a problem when there's an excess of oil causing aesthetic or health-related issues. The key is balance.
