Generally, it is not recommended to wash your natural hair with most bar soaps.
Your hair has a specific natural balance that is important for its health and appearance. Understanding this balance helps explain why bar soap isn't the best choice.
Understanding Your Hair's Natural Balance
Your hair and scalp are naturally acidic.
- Natural pH Level: Your hair has a pH level of around 4.5.
- Importance of Acidity: This natural acidity is crucial because it helps keep your hair cuticle smooth and closed, protecting the hair shaft and preventing dryness. It also creates an environment that is less hospitable to bacteria.
Why Bar Soap Can Be Problematic
According to the reference, most bar soaps are alkaline. When an alkaline product is used on naturally acidic hair, it disrupts this delicate pH balance.
- pH Disruption: The high pH of bar soap can cause the hair cuticle to lift or open.
- Consequences: This disruption can lead to several issues, notably causing fizziness. It can also leave hair feeling dry, stripped of its natural oils, and prone to breakage.
| Feature | Natural Hair pH | Most Bar Soap pH | Effect on Hair |
|---|---|---|---|
| pH Level | Around 4.5 | Alkaline (High) | Significant disruption |
| Hair Cuticle | Stays smooth | Lifts/Opens | Damage, dryness |
| Appearance | Smooth, healthy | Prone to fizziness | Frizzy, dull |
Using products specifically formulated for hair, which are typically pH-balanced, is a better way to cleanse without causing damage or frizz.
